ES45 Service Guide

This system is designed to fully exploit the potential of the Alpha EV68 CB chip
by using a switch-based (or point-to-point) interconnect system. With a
traditional bus design, the processors, memory, and I/O modules share the bus.
As the number of bus users increases, the transactions interfere with one
another, increasing latency and decreasing aggregate bandwidth. With a
switch-based system, speed is maintained and little degradation in performance
occurs as the number of CPUs, memory, and I/O users increases.
The switched system interconnect uses a set of complex microprocessor support
chips that route the traffic over multiple paths. This chipset consists of one Cchip, two P-chips, and eight D-chips.
•

C-chip. Provides the command interface from the CPUs and main memory.
The C-chip allows each CPU to do transactions simultaneously.

•

D-chips. Provide the data path for the CPUs, main memory, and I/O.

•

P-chips. Provide the interface to the I/O with two buses per chip.

The chipset supports up to four CPUs and up to 32 Gbytes of memory.
Interleaving occurs when at least two sibling or nonsibling memory arrays are
used.
Two 256-bit memory buses support four memory arrays, yielding a maximum
8 Gbytes/sec system bandwidth. Transactions are ECC protected. Upon the
receipt of data, the receiver checks for data integrity and corrects any errors.

If a failure occurs that causes the system to shut down, pressing the
power button off and then on clears the shutdown condition and attempts
to power the system back on. Conditions that prevent the system from
powering on can be determined by entering the env command from the
remote management console (RMC) command line. The RMC is powered
separately from the rest of the system and can operate as long as one
power supply is plugged in. (See Chapter 7.)

ES45 Service Guide

Power LED (green). Lights when the power button is depressed and
system power passes initial checks.
Reset button. A momentary contact switch that restarts the system and
reinitializes the console firmware. Power-up messages are displayed, and
then the console prompt is displayed or the operating system boot
messages are displayed, depending on how the startup sequence has been
defined.
Halt LED (amber). Lights when you press the Halt button.
Halt button. Halts the system.
•

If the operating system is running, pressing the Halt button halts the
operating system and returns to the SRM console.

•

If the Halt button is latched when the system is reset or powered up,
the system halts in the SRM console. Systems that are configured to
autoboot cannot boot until the Halt button is unlatched.

Commands issued from the remote management console (RMC) can be used to
reset, halt, and power the system on or off.

CPU Card

An ES45 can have up to four CPU cards. The CPU card has an 8-Mbyte
second-level cache and a DC-to-DC converter that provides the
required voltage to the Alpha chip. Power-up diagnostics are stored in
a flash SROM on the card.

Figure 1–9 CPU Card

PK0271A

The EV68 CB microprocessor is a superscalar CPU with out-of-order execution
and speculative execution to maximize speed and performance. It contains four
integer execution units and dedicated execution units for floating-point add,
multiply, and divide. It has an instruction cache and a data cache on the chip.
Each cache is a 64 KB, two-way, set associative, virtually addressed cache that
has 64-byte blocks. The data cache is a physically tagged, write-back cache.
Each CPU card has an 8 MB secondary B-cache (backup cache) consisting of
dual data rate (DDR) static RAMs (SRAMs) that provide low latency and high
bandwidth. Each CPU card also has a DC−to−DC converter that provides the
required voltage to the Alpha chip.
See Chapter 6 for CPU configuration.

System Overview

Memory Architecture
Memory throughput in this system is maximized by the following features:
•

Two independent, wide memory data buses

•

Very low memory latency (120 ns) and high bandwidth with 125 MHz clock

•

ECC memory

Each data bus is 256 bits wide (32 bytes). The memory bus speed is 125 MHz.
This yields 4 GB/sec bandwidth per bus (32 x 125 MHz = 4 GB/sec). The
maximum bandwidth is 8 GB/sec.
The switch interconnect design takes full advantage of the capabilities of the
two wide data buses. The 256 data bits are distributed equally over two
memory motherboards (MMBs). Simultaneously, in a read operation, 128 bits
come from one MMB and the other 128 bits come from another MMB, to make
one 256-bit read. Another 256-bit read operation can occur at the same time on
the other independent data bus.
In addition, two address buses per MMB (one for each array) allow overlapping/
pipelined accesses to maximize use of each data bus. When all arrays are
identical (same size), the memory is interleaved; that is, sequential blocks of
memory are distributed across all four arrays.
Memory Options
Each memory option consists of a set of four 125 MHz, 200-pin JEDEC-standard
DIMMs with PECL clocks. The DIMMs are synchronous DRAMs. Memory
options are available in the following sizes:
•

512 Mbytes (128 MB DIMMs)

•

1 Gbyte (256 MB DIMMs)

•

2 Gbytes (512 MB DIMMs)

•

4 Gbytes (1 GB DIMMs)

Memory options are installed into memory motherboards (MMBs) located on the
system motherboard (see Figure 1–8). There are four MMBs. The MMBs have
either four or eight slots for installing DIMMs. See Chapter 6 for memory
configuration.

CAUTION: PCI modules designed specifically for 5.0 volts or 3.3 volts are keyed
differently. Check the keying before you install the PCI module and
do not force it in. Plugging a module into a wrong slot can damage
it.
PCI Bus Implementation
•

Is fully compliant with the PCI Version 2.2 Specification.

•

Operates at delivering a peak bandwidth of 1.8 GB/sec; over 533 Mbytes/sec
for each 66 MHz bus and over 266 Mbytes/sec for the 33 MHz bus.

•

Has ten option slots (seven of which are hot swap).

•

Supports three address spaces: PCI I/O, PCI memory, and PCI configuration
space

•

Supports byte/word, tri-byte, quadword, and longword operations

•

Exists in noncached address space only

I/O Implementation
The system has 10 I/O slots, with six slots at 66 MHz and four slots at 33 MHz.
The Acer Labs 1543C chip provides the bridge from PCI 0 to ISA. The C-chip
controls accesses to memory on behalf of both P-chips.

1.12 Remote System Management Logic
The remote system management logic consists of two major elements:
the system power controller (SPC), used to monitor and control system
power supplies, regulators, and cooling apparatus; and the remote
management console (RMC), which facilitates remote interrogation
and control of the system. The components used within the remote
system management logic are powered by the AUX_5V supply, which is
always present whenever AC input power is available to the system.

Dual-Port RAM (DPR)
The ES45 system features a dual-port RAM—RAM that is shared between the
RMC and the system motherboard logic—to ease communication between the
system and the RMC. This book refers to the dual-port RAM as the DPR.
The RMC reads 256 bytes of data from each FRU EEPROM at power-up and
stores it in the DPR. This data contains configuration and possibly error log
information. The data is accessible via the TIG chip to the firmware for
configuration information during start-up. Remote or local applications can read
the error log and configuration information. The error log information is
written to the DPR by Compaq Analyze (see Chapter 5) and then written back
to the EEPROMs by the RMC. This ensures that the error log is available on a
FRU after power has been lost.
•

Section 1.12.1 describes the SPC logic.

•

Section 1.12.2 describes the RMC logic.

1-22

ES45 Service Guide

1.12.1 System Power Controller (SPC)
The system power controller (SPC) is responsible for sequencing the
turn-on/turn-off of all power supplies and regulators, monitoring all
system power supplies and regulators, generating hardware resets to
all logic elements, and generating power system status signals for use
by other functional units within the system. Additionally, it is
responsible for emergency shutdown if the internal system
temperature exceeds permissible limits.
An 8-bit CMOS microprocessor (PIC 17C44) with associated programming
controls the functions of the SPC. The PIC processor receives inputs from:
•

Operator control panel (power-on, reset)

•

Power supplies and DC/DC regulators (Power-OK)

•

Thermal sensors (temperature failure)

•

TIG chip (command bus from the firmware)

•

Remote management console logic (remote power up/down, reset)

It provides outputs to:
•

Power supplies and DC/DC regulators (power supply enables)

•

Processors (DC_OK, reset)

•

TIG bus chip (handshake)

•

Remote management console (power status)

System Overview

1-23

1.12.2 Remote Management Console (RMC)
The remote management console (RMC) provides a mechanism for
remotely monitoring a system and manipulating it on a very low level.
It also provides access to the repository for all error information in the
system. This provides the operator, either remotely or locally, with the
ability to monitor the system (voltages, temperature, fans, error status)
and manipulate it (reset, power on/off, halt) without any interaction on
the part of the operating system.
The RMC can also detect alert conditions such as overtemperature, fan failure,
and power supply failure and automatically dial a user-defined pager phone
number or another computer system to make the remote operator aware of the
alert condition.
The RMC logic is implemented using an 8-bit microprocessor (PIC 17C44) as the
primary control device. Support devices include:
•

Flash RAM (for code storage)

•

Address latch

•

Dual universal asynchronous receiver/transmitter (DUART)

•

8-bit I2C port expanders

•

I2C temperature sensors

•

I2C nonvolatile memories (NVRAM)

•

Programmable array logic (PAL)

•

Dual-port RAM (DPR)

•

RS232 drivers and receivers

2.1

Questions to Consider

Before troubleshooting any system problem, first check the site
maintenance log for the system's service history.
Be sure to ask the system manager the following questions:
• Has the system been used and did it work correctly?
•

Have changes to hardware or updates to firmware or software been made to
the system recently? If so, are the revision numbers compatible for the
system? (Refer to the system release notes.)

•

What is the current state of the system?

If the operating system is down, but you are able to access the SRM
console, use the console environment diagnostic tools, including the
OCP display, power-up display, and SRM commands.

If you are unable to access the SRM console, enter the RMC CLI and
issue commands to determine the hardware status. See Chapter 7.

If the operating system has crashed and rebooted, the CCAT (Compaq

Crash Analysis Tool), the Compaq Analyze service tools (to interpret
error logs), the SRM crash command, and operating system exercisers
can be used to diagnose system problems.

2-2 ES45 Service Guide

2.2

Diagnostic Tables

System problems can be classified into the following five categories.
Using these categories, you can quickly determine a starting point for
diagnosis and eliminate the unlikely sources of the problem.
1. Power problems—Table 2–1
2. No access to console mode—Table 2–2
3. Console-reported failures—Table 2–3
4. Boot problems—Table 2–4
5. Errors reported by the operating system—Table 2–5

WARNING: To prevent injury, access is limited to persons who
have appropriate technical training and experience. Such
persons are expected to understand the hazards of working
within this equipment and take measures to minimize danger to
themselves or others. These measures include:

2.3

Service Tools and Utilities

This section lists some of the tools and utilities available for
acceptance testing and diagnosis and gives recommendations for their
use.

2.3.1

Error Handling/Logging Tools (Compaq Analyze)

The operating systems provide fault management error detection, handling,
notification, and logging.
The primary tool for error handling is Compaq Analyze, a fault analysis utility
designed to analyze both single and multiple error/fault events. Compaq
Analyze uses error/fault data sources other than the traditional binary error
log. See Chapter 5.

2.3.2

Loopback Tests

Internal and external loopback tests are used to test the components on the I/O
connector assembly (“junk I/O”) and to test Ethernet cards. The loopback tests
are a subset of the SRM diagnostics.
Use loopback tests to isolate problems with the COM2 serial port, the parallel
port, and Ethernet controllers. See the test command in Chapter 4 for
instructions on performing loopback tests.

2.3.3

SRM Console Commands

SRM console commands are used to set and examine environment variables and
device parameters. For example, the show configuration and show device
commands are used to examine the configuration, and the set envar and show
envar commands are used to set and view environment variables.
SRM commands are also used to invoke ROM-based diagnostics and to run
native exercisers. For example, the test and sys_exer commands are used to
test the system.
See Chapter 6 for information on configuration-related console commands and
environment variables. See Chapter 4 for information on running console
exercisers. See Appendix A for a list of console commands used most often on
ES45 systems.

Troubleshooting 2-9

2.3.4

Remote Management Console (RMC)

The remote management console (RMC) is used for managing the server either
locally or remotely. It also plays a key role in error analysis by passing error log
information to the dual-port RAM (DPR), which is shared between the RMC and
the system motherboard logic, so that this information can be accessed by the
system. RMC also controls the control panel display. RMC has a command-line
interface from which you can enter a few diagnostic commands.
RMC can be accessed as long as the power cord for a working supply is plugged
into the AC wall outlet and a console terminal is attached to the system. This
feature ensures that you can gather information when the operating system is
down and the SRM console is not accessible. See Chapter 7.

2.3.5

Crash Dumps

For fatal errors, the operating systems save the contents of memory to a crash dump
file. This file can be used to determine why the system crashed.
CCAT, the Compaq Crash Analysis Tool, is the primary crash dump analysis tool for
analyzing crash dumps on Alpha systems. CCAT compares the results of a crash
dump with a set of rules. If the results match one or more rules, CCAT notifies the
system user of the cause of the crash and provides information to avoid similar
crashes in the future.

2.3.6

Revision and Configuration Management Tool (RCM)

RCM is a tool to assist with revision and configuration management for
hardware, firmware, operating system, and software products. It collects
configuration and revision data from a system and stores it. A report generator
produces configuration, change, and comparison reports that are useful in
finding revision incompatibilities. RCM also helps you verify service actions.
For example, if a new board was supposed to be installed, you can use RCM to
verify that the installation was done.
RCM is accessible from the following Web site:
http://smsat-www.ilo.dec.com/products/rcm/service/index.htm

2-10 ES45 Service Guide

2.4

Q-Vet Installation Verification

CAUTION: Customers are not authorized to access, download, or use QVet. Q-Vet is for use by Compaq engineers to verify the system
installation. Misuse of Q-Vet may result in loss of customer data.
Q-Vet is the Qualification Verifier Exerciser Tool that is used by Compaq
engineers to exercise systems under development. Compaq recommends
running the latest Q-Vet released version to verify that hardware is installed
correctly and is operational. Q-Vet does not verify specific operating system or
layered product configurations.
The latest Q-Vet release, information, Release Notes, and documentation are
located at http://chump2.mro.cpqcorp.net/qvet/.
If the system has been partitioned, Q-Vet must be installed and run separately
on each partition to verify the complete system. Compaq recommends that
Compaq Analyze be installed on the operating system prior to running Q-Vet.
CAUTION:
Do not install the Digital System Verification Software (DECVET) on the
system; use Q-Vet instead.
Non-IVP Q-Vet scripts verify disk operation for some drives with "write enabled"
techniques. These are intended for Engineering and Manufacturing Test.
Run ONLY IVP scripts on systems that contain customer data or any
other items that must not be written over. See the Q-Vet Disk Testing
Policy Notice on the Q-Vet Web site for details. All Q-Vet IVP scripts use
Read Only and/or File I/O to test hard drives. Floppy and tape drives
are always write tested and should have scratch media installed.
Q-Vet must be de-installed upon completion of system verification.

Troubleshooting 2-11

Swap or Pagefile Space
The system must have adequate swap space (on Tru64 UNIX) or pagefile space
(on OpenVMS) for proper Q-Vet operation. You can set this up either before or
after Q-Vet installation.
During initialization, Q-Vet will display a message indicating the minimum
amount of swap/pagefile needed, if it determines that the system does not have
enough. You can then reconfigure the system.
If you wish to address the swap/pagefile size before running Q-Vet, see the
Swap/Pagefile Estimates on the Q-Vet Web site.

2-12 ES45 Service Guide

2.4.1

Installing Q-Vet

The procedures for installation of Q-Vet differ between operating
systems. You must install Q-Vet on each partition in the system.
Install and run Q-Vet from the SYSTEM account on VMS and the root account
on UNIX. Remember to install Q-Vet in each partition.
Tru64 UNIX
1. Make sure that there are no old Q-Vet or DECVET kits on the system by
using the following command:
setld -i | grep VET
Note the names of any listed kits, such as OTKBASExxx etc., and remove
the kits using qvet_uninstall if possible. Otherwise use the command
setld -d
kit1_name kit2_name
kit3_name
2. Copy the kit tar file (QVET_Vxxx.tar) to your system.
3. Be sure that there is no directory named output. If so move to another
directory or remove the output directory.
rm -r output
4. Untar the kit with the command
tar xvf
QVET_Vxxx.tar
Note: The case of the file name may be different depending upon how it was
stored on the system. Also, you may need to enclose the file name in
quotation marks if a semi-colon is used.
5. Install the kit with the command
setld -l output
6. During the install, if you intend to use the GUI you must select the optional
GUI subset (QVETXOSFxxx).
7. The Q-Vet installation will size your system for devices and memory. It also
runs qvet_tune. You should answer 'y' to the questions that are asked
about setting parameters. If you do not, you may have trouble running
Q-Vet. After the installation completes, you should delete the output
directory with rm -r output. You can also delete the kit tar file.
8. You must reboot the system before starting Q-Vet.
9. On reboot you can start Q-Vet GUI via vet& or you can run non GUI
(command line) via vet –nw.

Troubleshooting 2-13

OpenVMS
1. Delete any QVETAXPxxx.A or QVETAXPxxx.EXE file from the current
directory.
2. Copy the self-extracting kit image file (QVETAXPxxx.EXE) to the current
directory.
3. It is highly recommended, but not required, that you purge the system disk
before installing Q-Vet. This will free up space that may be needed for
pagefile expansion during the AUTOGEN phase.
$purge sys$sysdevice:[*…]*.*
4. Extract the kit saveset with the command $run QVETAXPxxx.EXE and
verify that the kit saveset was extracted by checking for the "Successful
decompression" message.
5. Use @sys$update:vmsinstal for the Q-Vet installation. The installation
will size your system for devices and memory. You should choose all the
default answers during the Q-Vet installation. This will verify the Q-Vet
installation, tune the system, and reboot. During the install, if you do not
intend to use the GUI, you can answer no to the question "Do you want to
install Q-Vet with the DECwindows Motif interface?"
6. After the installation completes you should delete the QVETAXP0xx.A file
and the QVETAXPxxx.EXE file.
7. On reboot you can start Q-Vet GUI via $vet or the command interface via
$vet/int=char.

prior to the long IVP script if desired, but not in place of the long IVP
script, which is the full IVP test.

The long IVP will run until the slowest device has completed one pass (typically
2 to 12 hours). This is called a Cycle of Testing.

2-16 ES45 Service Guide

2.4.3

Reviewing Results of the Q-Vet Run

After running Q-Vet, check the results of the run by reviewing the
summary log.
If you follow the above steps, Q-Vet will run all exercisers until the slowest
device has completed one full pass. Depending on the size of the system
(number of CPUs and disks), this will typically take 2 to 12 hours. Q-Vet will
then terminate testing and produce a summary log. The termination message
will tell you the name and location of this file.
All exerciser processes can also be manually terminated with the Suspend and
Terminate buttons (stop and terminate commands).
After all exercisers report “Idle,” the summary log is produced containing Q-Vet
specific results and statuses.
A. If there are no Q-Vet errors, no system event appendages, and testing
ran to the specified completion time, the following message will be
displayed:
”Q-Vet Tests Complete: Passed”
B. Otherwise, a message will indicate:
”Additional information may be available from Compaq
Analyze”
It is recommended that you run Compaq Analyze to review test results. The
testing times (for use with Compaq Analyze) are printed to the Q-Vet run
window and are available in the summary log.

Troubleshooting 2-17

2.4.4

De-Installing Q-Vet

The procedures for de-installation of Q-Vet differ between operating
systems. You must de-install Q-Vet from each partition in the system.
Failure to do so may result in the loss of customer data at a later date if
Q-Vet is misused.
Follow the instructions listed under your operating system to de-install Q-Vet
from a partition. The qvet_uninstall programs will remove the Q-Vet supplied
tools and restore the original system tuning/configuration settings.

Tru64 UNIX
1. Stop, Terminate, and Exit from Q-Vet testing.

3.1

Overview of Power-Up Diagnostics

The power-up process begins with the power-on of the power supplies.
After the AC and DC power-up sequences are completed, the remote
management console (RMC) reads EEROM information and deposits it
into the DPR. The SROM minimally tests the CPUs, initializes and
tests backup cache, and minimally tests memory. Finally, the SROM
loads the SRM console program into memory and jumps to the first
instruction in the console program.
There are three distinct sets of power-up diagnostics:
1.

System power controller and remote management console diagnostics—
These diagnostics check the power regulators, temperature, and fans.
Failures are reported in the dual-port RAM (DPR) and on the OCP display.
Certain failures may prevent the system from powering on.

Serial ROM (SROM) diagnostics—SROM tests check the basic functionality
of the system and load the console code from the FEPROM on the system
motherboard into system memory. Failures during SROM tests are
indicated by error beep codes and messages on the serial console terminal
and the OCP.

Console firmware diagnostics—These tests are executed by the SRM console
code. They test the core system, including boot path devices. Failures
during these tests are reported to the console terminal through the powerup screen or console event log.

3-2

ES45 Service Guide

3.2

System Power-Up Sequence

The power-up sequence is described below and illustrated in
Figure 3–1.
1. When the power cord is plugged into the wall outlet, 5V auxiliary AC
voltage is enabled. The 5 V AUX LEDs on the power supplies are lit, and
the system power controller and RMC are initialized.
2. Pressing the Power button on the control panel or subsequently issuing the
power-on command from the RMC turns on power to the power supplies,
CPU converters, and VTERM regulators. The POK LEDs on the power
supplies are lit and the power supplies are tested. If all power supplies are
bad, power-up stops. All DC/DC converters and regulators are then tested.
If any converter or regulator is bad, power-up stops.
3. CPU_DCOK and SYS_DC_OK are set to “true,” which means that DC power
on the CPUs and system is okay. All CPUs load the initial Y divisor (clock
multiplier). The OCP power LED is lit.
4. SYS_RESET is set to “false.” This setting releases the system motherboard
logic and PCI backplane logic from the Reset state.
5. The primary CPU is selected and CPU_(P)_RESET is set to “false.” This
allows the primary CPU to attempt to load flash SROM code.
6. If the primary CPU is good, it loads flash SROM. If bad, the system tries
the next available CPU and if that CPU is good, it becomes the primary.
The remaining CPUs load flash SROM. The SROM power-up then
continues, as described in Section 3.3.

SROM Power-Up Sequence

When the system powers up, the SROM code is loaded into the I-cache

(instruction cache) on the first available CPU, which becomes the primary
CPU. The order of precedence is CPU0, CPU1, and so on. The primary
CPU attempts to access the PCI bus. If it cannot, either a hang or a failure
occurs, and this is the only message displayed.

The primary CPU interrogates the I C EEROM on the system board and
2

CPU modules through shared RAM. The primary CPU determines the
CPU and system configuration to jump to.
The primary CPU next checks the SROM checksum to determine the
validity of the flash SROM sectors.

If flash SROM is invalid, the primary CPU reports the error and continues
the execution of the SROM code. Invalid flash SROM must be
reprogrammed.
If flash SROM is good, the primary CPU programs appropriate registers
with the values from the flash data and selects itself as the target CPU to
be loaded.

The primary CPU (usually CPU0) initializes and tests the B-cache and

memory, then loads the flash SROM code to the next CPU. That CPU then
initializes the EV68 chip) and marks itself as the secondary CPU. Once
the primary CPU sees the secondary, it loads the flash SROM code to the
next CPU until all remaining CPUs are loaded.

The flash SROM performs B-cache tests. For example, the ECC data test
verifies the detection logic for single- and double-bit errors.

ES45 Service Guide

SROM Power-Up Sequence

The primary CPU initiates all memory tests. The memory is tested for

address and data errors for the first 32 MB of memory in each array. It
also initializes all the “sized” memory in the system.
If a memory failure occurs, an error is reported. An untested memory
array is assigned to address 0 and the failed memory array is de-assigned.
The memory tests are rerun on the first 32 MB of memory in the
remaining arrays. If all memory fails, the “No Memory Available” message
is reported and the system halts.

If all memory passes, the primary CPU loads the console and transfers
control to it.

SRM Console Power-Up Display

When SROM power-up is complete, the primary CPU transfers control
to the SRM console program. The console program continues the
system initialization. Failures are reported to the console terminal
through the power-up screen and a console event log.
The following section shows the messages that are displayed once the SROM
has transferred control to the SRM console.

The primary CPU prints a message indicating that it is running the console.
Starting with this message, the power-up display is sent to any console
terminal, regardless of the state of the console environment variable.

If console is set to graphics, the display from this point on is saved in a
memory buffer and displayed on the VGA monitor after the PCI buses are
sized and the VGA device is initialized.

The memory size is determined and memory is tested.
 The I/O subsystem is probed and I/O devices are reported. I/O adapters are
configured.

3.4.2

Checksum Error

If no messages are displayed on the operator control panel after the
Jump to Console message, the console firmware is corrupted. When
the system detects the error, it attempts to load a utility called the failsafe loader (FSL) so that you can load new console firmware images. A
sequence similar to the one in Example 3–4 occurs.

SRM Console Diagnostics

This chapter describes troubleshooting with the SRM console.
The SRM console firmware contains ROM-based diagnostics that allow you to
run system-specific or device-specific exercisers. The exercisers run concurrently to provide maximum bus interaction between the console drivers and the
target devices.
Run the diagnostics by using commands from the SRM console. To run the
diagnostics in the background, use the background operator “&” at the end of
the command. Errors are reported to the console terminal, the console event
log, or both.
If you are not familiar with the SRM console, see the ES45 Owner’s Guide.

buildfru
2

The buildfru command initializes I C bus EEPROM descriptive data
structures for the named FRU and initializes its SDD and TDD error
logs. This command uses data supplied on the command line to build
the FRU descriptor. Buildfru is used by Manufacturing, FRU repair
operations, or Field Service.

Example 4–1 buildfru
P00>>> buildfru smb0.mmb0.J3 54-24941-EA NI90200100
P00>>> buildfru smb0.cpu0 30-30158-05.AX05 NI94060554 Compaq

P00>>> buildfru -s smb0.mmb0.J3 80 47 46 45 44 43 42 41

Building of the FRU descriptor on a DIMM, passing a part number and a
serial number
 Building of the FRU descriptor on a CPU, passing a part number, serial

 Building of the FRU descriptor on a DIMM with the -s qualifier, pass offset
80, and value of 45
 Building of the FRU descriptor on a DIMM with the -s qualifier, pass offset

The buildfru command is used for several purposes:
•

By Manufacturing to build a FRU table containing a description of each
FRU in the system

•

By FRU repair operations for initializing good stocking spares

•

By Field Service to make any FRU descriptor adjustments required by the
customer.

ES45 Service Guide

The information supplied on the buildfru command line includes the console
name for the FRU, part number, serial number, model number, and optional
information. The buildfru command facilitates writing the FRU information to
the EEPROM on the device.
Use the show fru command to display the FRU table created with buildfru.
Use the show error command to display FRUs that have errors logged to them.
Typically, you only need to use buildfru in Field Service if you replace a device
for which the information displayed with the show fru command is inaccurate
or missing. After replacing the device, use buildfru to build the new FRU
descriptor.
NOTE: Be sure to enter the FRU information carefully. If you enter incorrect
information, the callout used by Compaq Analyze will not be accurate.
Three areas of the EEPROM can be initialized: the FRU generic data, the FRU
specific data, and the system specific data. Each area has its own checksum,
which is recalculated any time that segment of the EEPROM is written.
When the buildfru command is executed, the FRU EEPROM is first flooded
with zeros and then the generic data, the system specific data, and EEPROM
format version information are written and checksums are updated. For certain
FRUs, such as CPU modules, additional FRU “specific” data can be entered
using the -s option. This data is written to the appropriate region, and its
corresponding checksum is updated.
FRU Assembly Hierarchy
Alpha-based systems can be decomposed into a collection of FRUs. Some FRUs
carry various levels of nested FRUs. For instance, the system motherboard is a
FRU that carries a number of “child” FRUs. A child, such as a memory
motherboard (MMB), may carry a number of its own children, DIMMs. The
naming convention for FRUs represents the assembly hierarchy.
The following is the general form of a FRU name:
<frun>[.<frun>[.<frun>]]
The fru is a placeholder for the appropriate FRU type at that level and n is the
number of that FRU instance on that branch of the system hierarchy.

SRM Console Diagnostics 4-7

The ES45 FRU assembly hierarchy has three levels. The FRU types from the
top to the bottom of the hierarchy are as follows:
Level

FRU Type

Meaning

First Level

SMB
JIO
OCP
PWR (0–2)
FAN

System motherboard
I/O connector module (junk I/O)
Operator control panel
Power supplies
Fans

Second Level

CPU (0–3)
MMB (0–3)
CPB

CPUs
Memory motherboards
PCI backplane

Third Level

J (2–9)
PCI (0–9)
SBM (0–1)

Memory DIMMs
PCI slots
SCSI backplane

To build a FRU descriptor for a lower level FRU, point back to the higher level
FRUs to which it is associated. For example, to build a descriptor for a DIMM,
point back to the MMB on which it resides and then to the system motherboard.
All fields are automatically set to uppercase before writing to EEPROM. See
Example 4–1.
If you enter the buildfru data correctly for a device that has an EEPROM to
program, nothing is displayed after you enter the command. If you enter
incorrect data or the device does not have an EEPROM to program, an error
message similar to the following is displayed:
P00>>>
P00>>> buildf fan4 54-12345-01.a001 ay84412345

Deposit
The deposit command stores data in the location specified. If no options are
given, the system uses the options from the preceding deposit command.
If the specified value is too large to fit in the data size listed, the console ignores
the command and issues an error. If the data is smaller than the data size, the
higher order bits are filled with zeros.
In Example 4–4:

Clear first 512 bytes of physical memory
 Deposit 5 into four longwords starting at virtual memory address 1234.
 Load GPRs R0 through R8 with -1.

exer

The exer command exercises one or more devices by performing
specified read, write, and compare operations. Typically exer is run
from the built-in console script. Advanced users may want to use the
specific options described here. Note that running exer on disks can be
destructive.
Optionally, exer reports performance statistics:
•

A read operation reads from a device that you specify into a buffer.

•

A write operation writes from a buffer to a device that you specify.

•

A compare operation compares the contents of the two buffers.

The exer command uses two buffers, buffer1 and buffer2, to carry out the
operations. A read or write operation can be performed using either buffer. A
compare operation uses both buffers.

Example 4–5 exer
P00>>> exer dk*.* -p 0 -secs 36000

Read SCSI disks for the entire length of each disk. Repeat this until 36000
seconds, 10 hours, have elapsed. All disks will be read concurrently. Each block
read will occur at a random block number on each disk.
P00>>> exer -l 2 dka0

Read block numbers 0 and 1 from device dka0.
P00>>> exer -sb 1 -eb 3 -bc 4 -a 'w' -d1 '0x5a' dka0

Write hex 5a's to every byte of blocks 1, 2, and 3. The packet size is bc * bs, 4 *

P00>>> exer -eb 64 -bc 4 -a '?w-Rc' dka0

A destructive write test over block numbers 0 through 100 on disk dka0. The
packet size is 2048 bytes. The action string specifies the following sequence of
operations:
1. Set the current block address to a random block number on the disk
between 0 and 97. A four block packet starting at block numbers 98, 99, or
100 would access blocks beyond the end of the length to be processed so 97 is
the largest possible starting block address of a packet.
2. Write a packet of hex 5a's from buffer1 to the current block address.
3. Set the current block address to what it was just prior to the previous write
operation.
4. From the current block address read a packet into buffer2.
5. Compare buffer1 with buffer2 and report any discrepancies.
6. Repeat steps 1 through 5 until enough packets have been written to satisfy
the length requirement of 101 blocks.

P00>>> exer -a '?r-w-Rc' dka0
A nondestructive write test with packet sizes of 512 bytes. Use this test only if
the customer has a current backup of any disks being tested. The action string
specifies the following sequence of operations:
1. Set the current block address to a random block number on the disk.
2. From the current block address on the disk, read a packet into buffer1.
3. Set the current block address to the device address where it was just before
the previous read operation occurred.
4. Write the contents of buffer1 back to the current block address.
5. Set the current block address to what it was just prior to the previous write
operation.

4-18

ES45 Service Guide

6. From the current block address on the disk, read a packet into buffer2.
7. Compare buffer1 with buffer2 and report any discrepancies.
8. Repeat the above steps until each block on the disk has been written once
and read twice.
You can tailor the behavior of exer by using options to specify the following:
•

An address range to test within the test device(s)

•

The packet size, also known as the I/O size, which is the number of bytes
read or written in one I/O operation

•

The number of passes to run

•

How many seconds to run

•

A sequence of individual operations performed on the test devices. The
qualifier is called the action string qualifier.

Options
-sb <start_block>

Specifies the starting block number (hex) within
filestream. The default is 0.

-eb <end_block>

Specifies the ending block number (hex) within
filestream. The default is 0.

-p <pass_count>

Specifies the number of passes to run the exerciser. If 0,
then run forever or until Ctrl/C. The default is 1.

-l <blocks>

Specifies the number of blocks (hex) to exercise. -l has
precedence over -eb. If only reading, then specifying
neither -l nor -eb defaults to read till eof. If writing, and
neither -l nor -eb are specified then exer will write for

SRM Console Diagnostics 4-19

the size of device. The default is 1.
-bs <block_size>

Specifies the block size (hex) in bytes. The default is 200
(hex).

-bc <block_per_io>

Specifies the number of blocks (hex) per I/O. On devices
without length (tape), use the specified packet size or
default to 2048. The maximum block size allowed with
variable length block reads is 2048 bytes. The default
is 1.

-d1 <buf1_string>

String argument for eval to generate buffer1 data
pattern from. Buffer1 is initialized only once before any
I/O occurs. Default = all bytes set to hex 5A's.

-d2 <buf2_string>

String argument for eval to generate buffer2 data
pattern from. Buffer2 is initialized only once before any
I/O occurs. Default = all bytes set to hex 5A's.

-a <action_string>

Specifies an exerciser action string, which determines
the sequence of reads, writes, and compares to various
buffers. The default action string is ?r. The action string
characters are:

4-20

•

W Write from buffer1.

•

Read into buffer2.

•

Write from buffer2.

•

N Write without lock from buffer1.

•

Write without lock from buffer2.

•

Compare buffer1 with buffer2.

•

Seek to file offset prior to last read or write.

ES45 Service Guide

Read into buffer1.

-a <action_string>
(continued)

•

?
Seek to a random block offset within the
specified range of blocks. exer calls the program,
random, to “deal” each of a set of numbers once. exer
chooses a set that is a power of two and is greater
than or equal to the block range. Each call to random
results in a number that is then mapped to the set of
numbers that are in the block range and exer seeks
to that location in the filestream. Since exer starts
with the same random number seed, the set of
random numbers generated will always be over the
same set of block range numbers.

•

s Sleep for a number of milliseconds specified by
the delay qualifier. If no delay qualifier is present,
sleep for 1 millisecond. Times as reported in verbose
mode will not necessarily be accurate when this
action character is used.

•

Zero buffer 1

•

Zero buffer 2

•

Add constant to buffer 1

•

Add constant to buffer 2

-sec <seconds>

Specifies to terminate the exercise after the number of
seconds have elapsed. By default the exerciser continues
until the specified number of blocks or passcount are
processed.

-m

Specifies metrics mode. At the end of the exerciser a
total throughput line is displayed.

-v

Specifies verbose mode. Data read is also written to
stdout. This is not applicable on writes or compares. The
default is verbose mode off.

-delay <millisecs>

Specifies the number of milliseconds to delay when s
appears as a character in the action string.

grep

The grep command is very similar to the UNIX grep command. It
allows you to search for “regular expressions”—specific strings of
characters—and prints any lines containing occurrences of the strings.
Using grep is similar to using wildcards.

Example 4–7 grep
P00>>> show fru | grep PCI
SMB0.CPB0.PCI1 0 DE500-BA Network Cont
SMB0.CPB0.PCI4 0 DEC PowerStorm
SMB0.CPB0.PCI5 0 NCR 53C895
P00>>>

In Example 4–7 the output of the show fru command is piped into grep (the
vertical bar is the piping symbol), which filters out only lines with “PCI.”
Grep supports the following metacharacters:
^

Matches beginning of line

Matches end of line

Matches any single character

[]

Set of characters; [ABC] matches either 'A' or 'B' or 'C'; a dash (other than first or
last of the set) denotes a range of characters: [A-Z] matches any uppercase letter;
if the first character of the set is '^' then the sense of match is reversed: [^0-9]
matches any non-digit; several characters need to be quoted with backslash (\) if
they occur in a set: '\', ']', '-', and '^'

Repeated matching; when placed after a pattern, indicates that the pattern
should match any number of times. For example, '[a-z][0-9]*' matches a lowercase
letter followed by zero or more digits.

Repeated matching; when placed after a pattern, indicates that the pattern
should match one or more times '[0-9]+' matches any non-empty sequence of
digits.

Optional matching; indicates that the pattern can match zero or one times.
'[a-z][0-9]?' matches lowercase letter alone or followed by a single digit.

Quote character; prevent the character that follows from having special meaning.

SRM Console Diagnostics 4-23

Syntax
grep ( [-{c|i|n|v}] [-f <file>] [<expression>] [<file>...] )
Arguments
<expression>

Specifies the target regular expression. If any regular
expression metacharacters are present, the expression
should be enclosed with quotes to avoid interpretation by the
shell.

<file>...

Specifies the files to be searched. If none are present, then
standard input is searched.

Options
-c

Print only the number of lines matched.

-i

Ignore case. By default grep is case sensitive.

-n

Print the line numbers of the matching lines.

-v

Print all lines that do not contain the expression.

-f <file>

Take regular expressions from a file, instead of command.

If the memory configuration is very large, the console might not test all of the
memory. The upper limit is 1 GB.
Use the show_status command to display the progress of the tests. Use the
kill or kill_diags command to terminate the test.
Syntax
memexer [number]
Arguments
[number]

Number of memory exercisers to start. The default is 1.
The number of exercisers, as well as the length of time for testing,
depends on the context of the testing.

Use the show memory command or an info 0 command to see where
memory is located.
 Starting address
 Length of the section to test in bytes
 Passcount. In this example, the test will run for 10 passes.
 The test detected a failure on DIMM 3, which is located on MMB 2.
Use the show_status command to display the progress of the test. Use the kill
or kill_diags command to terminate the test.
Memtest provides a graycode memory test. The test writes to memory and
then reads the previously written value for comparison. The section of memory
that is tested has its data destroyed. The -z option allows testing outside of the
main memory pool. Use caution because this option can overwrite the console.
Memtest may be run on any specified address. If the -z option is not included
(default), the address is verified and allocated from the firmware's memory
zone. If the -z qualifier is included, the test is started without verification of the
starting address.
When a starting address is specified, the memory is allocated beginning at the
starting address -32 bytes for the length specified. The extra 32 bytes that are
allocated are reserved for the allocation header information. Therefore, if a
starting address of 0xa00000 and a length of 0x100000 is requested, the area
from 0x9fffe0 through 0xb00000 is reserved. This may be confusing if you try to
begin two memtest processes simultaneously with one beginning at 0xa00000
for a length of 0x100000 and the other at 0xb00000 for a length of 0x100000.
The second memtest process will send a message that it is “Unable to allocate
memory of length 100000 at starting address b00000.” Instead, the second
process should use the starting address of 0xb00020.

SRM Console Diagnostics 4-45

NOTE: If memtest is used to test large sections of memory, testing may take a
while to complete. If you issue a Ctrl/C or kill PID in the middle of
testing, memtest may not abort right away. For speed reasons, a check
for a Ctrl/C or kill is done outside of any test loops. If this is not
satisfactory, you can run concurrent memtest processes in the
background with shorter lengths within the target range.
Memtest Test 1 — Graycode Test
Memtest Test 1 uses a graycode algorithm to test a specified section of memory.
The graycode algorithm used is: data = (x>>1)^x, where x is an incrementing
value.
Three passes are made of the memory under test.
•

The first pass writes alternating graycode inverse graycode to each four
longwords. This causes many data bits to toggle between each 16-byte write.
For example graycode patterns for a 32 byte block would be:
Graycode(0) 00000000 Graycode(1) 00000001 Graycode(2) 00000003
Graycode(3) 00000002 Inverse Graycode(4) FFFFFFF9 Inverse Graycode(5)
FFFFFFF8 Inverse Graycode(6) FFFFFFFA Inverse Graycode(7)
FFFFFFFB

•

The second pass reads each location, verifies the data, and writes the
inverse of the data, one longword at a time. This causes all data bits to be
written as a one and zero.

•

The third pass reads and verifies each location.

You can specify the -f (fast) option so that the explicit data verify sections of the
second and third loops are not performed. This does not catch address shorts
but stresses memory with a higher throughput. The ECC/EDC logic can be used
to detect failures.

[-t <test_mask>] [-se <soft_error_threshold>]
[-g <group_name>] [-rb] [-f] [-m] [-z] [-h] [-mb] )
Options
-sa

Start address. Default is first free space in memzone.

-ea

End address. Default is start address plus length size.

-l

Length of section to test in bytes, default is the zone size with the
-rb option and the block_size for all other tests. -l has precedence
over -ea.

-bs

Block (packet) size in bytes in hex, default 8192 bytes. This is used
only for the random block test. For all other tests the block size
equals the length.

-i

Specifies the address increment value in longwords. This value is
used to increment the address through the memory to be tested.
The default is 1 (longword). This is only implemented for the
graycode test. An address increment of 2 tests every other
longword. This option is useful for multiple CPUs testing the same
physical memory.

-p

Passcount If 0 then run indefinitely or until Ctrl/C is issued.
Default = 1

-t

Test mask. Default = run all tests in selected group.

-g

Group name

-se

Soft error threshold

-f

Fast. If -f is included in the command line, the data compare is
omitted. Detects only ECC/EDC errors.

SRM Console Diagnostics 4-47

Options
-m

Timer. Prints out the run time of the pass. Default = off .

-z

Tests the specified memory address without allocation. Bypasses
all checking but allows testing in addresses outside of the main
memory heap. Also allows unaligned input.
CAUTION: This flag can overwrite the console. If the system
hangs, press the Reset button.

-d

Used only for march test (2). Uses this pattern as test pattern.
Default = 5's

-h

Allocates test memory from the firmware heap.

-rs

Used only for random test (3). Uses this data as the random seed
to vary random data patterns generated. Default = 0.

-rb

Randomly allocates and tests all of the specified memory address
range. Allocations are done of block_size.

-mb

Memory barrier flag. Used only in the -f graycode test. When set
an mb is done after every memory access. This guarantees serial
access to memory.

-ba

Used only for block test (4). Uses the data stored at this address to
write to each block.

4.16 nettest
The nettest command tests the network ports using MOP loopback.
Typically nettest is run from the built-in console script. Advanced
users may want to use the specific options and environment variables
described here.

Example 4–22 nettest
P00>>> nettest ei*
P00>>> nettest -mode in

P00>>> nettest -mode ex -w 10 e*

Internal loopback test on port ei*0
 Internal loopback test on ports ewa0/ewb0
 External loopback test on port eia0 or ewa0; wait 10 seconds between tests

SRM Console Diagnostics 4-51

Nettest performs a network test. It can test the ei* or ew* ports in internal
loopback, external loopback, or live network loopback mode.
Nettest contains the basic options to run MOP loopback tests. Many
environment variables can be set from the console to customize nettest before
nettest is started. The environment variables, a brief description, and their
default values are listed in the syntax table in this section. Each variable name
is preceded by e*a0_ or e*b0_ to specify the desired port.
You can change other network driver characteristics by modifying the port
mode. See the -mode option.
Use the show_status display to determine the process ID when terminating an
individual diagnostic test. Use the kill or kill_diags command to terminate
tests.

4.17 set sys_serial_num
The set sys_serial_num command sets the system serial number. This
command is used by Manufacturing for establishing the system serial
number, which is then propagated to all FRU devices that have
EEPROMs. The sys_serial_num environment variable can be read by
the operating system.

IMPORTANT: The system serial number must be set correctly. Compaq
Analyze will not work with an incorrect serial number.

Example 4–23 set sys_serial_num
P00>>> set sys_serial_num NI900100022

When the system motherboard (SMB) is replaced, you must use the set
sys_serial_num command to restore the master setting.

SYS_SERIAL_NUM Mismatch

ES45 Service Guide

The output of the show error command is based on information logged to the
serial control bus EEPROMs on the system FRUs. Both the operating system
and the ROM-based diagnostics log errors to the EEPROMs. This functionality
allows you to generate an error log from the console environment. No errors are
displayed for fans or the OCP because these components do not have an
EEPROM.
Syntax
show error
All FRUs with errors are displayed. If no errors are logged, nothing is displayed
and you are returned to the SRM console prompt.
Example 4–24 shows TDD, SDD, checksum, and sys_serial_num mismatch
errors logged to the EEPROM on the system motherboard (SMB0). Table 4–2
shows a reference to these errors. The bit masks correspond to the bit masks
that would be displayed in the E field of the show fru command.

FRU to which errors are logged; in this example the system motherboard,
SMB0.
 A TDD error has been logged. TDDs (test-directed diagnostics) test specific
functions sequentially. Typically, nothing else is running during the test.
TDDs are performed in SROM or XSROM or early in the console power-up
flow.

An SDD error has been logged. SDDs (symptom-directed diagnostics) are
generic diagnostic exercisers that try to cause random behavior and look
for failures or “symptoms.” All SDDs are logged by Compaq Analyze.

Three checksum errors have been logged.
 There was a mismatch between the serial number on the system

motherboard and the system serial number. This could occur if a
motherboard from a system with a different serial number was swapped
into this system.

Table 4–3 lists bit assignments for failures that could potentially be listed in the
E (error) field of the show fru command. Because the E field is only two
characters wide, bits are “or’ed” together if the device has multiple errors. For
example, the E field for a FRU with both TDD (02) and SDD (04) errors would
be 06:
010 | 100 = 110 (6)

ES45 Service Guide

Use the show_status command to display the progress of diagnostic tests.
The diagnostics started by the sys_exer command automatically reallocate
memory resources, because these tests require additional resources. Use the
init command to reconfigure memory before booting an operating system.
Because the sys_exer tests are run concurrently and indefinitely (until you stop
them with the init command), they are useful in flushing out intermittent
hardware problems.
When using the sys_exer command after shutting down an operating system,
you must initialize the system to a quiescent state. Enter the following
command at the SRM console:
P00>>> init
.
.
.
P00>>> sys_exer

By default, no write tests are performed on disk and tape drives. Media must be
installed to test the floppy drive and tape drives. When the -lb argument is
used, a loopback connector is required for the COM2 port (9-pin loopback
connector, 12-27351-01) and parallel port (25-pin loopback connector).
Syntax
sys_exer [-lb] [-t]
Arguments
[-lb]
The loopback option runs console loopback tests for the COM2 serial
port and the parallel port during the test sequence.
[-t]

Number of seconds to run. The default is run until terminated by a
kill or kill_diags command.

SRM Console Diagnostics 4-65

4.22 test
The test command verifies all the devices in the system. This command
can be used on all supported operating systems.

The test command also does a quick test on the system speaker. A beep is
emitted as the command starts to run.
The tests are run sequentially, and the status of each subsystem test is
displayed to the console terminal as the tests progress. If a particular device is
not available to test, a message is displayed. The test script does no destructive
testing; that is, it does not write to disk drives.
Syntax
test [argument]
Use the -lb (loopback) argument for console loopback tests.

4-66

ES45 Service Guide

To run a complete diagnostic test using the test command, the system
configuration must include:
•

A serial loopback connected to the COM2 port (not included)

•

A parallel loopback connected to the parallel port (not included)

•

A trial diskette with files installed

•

A trial CD-ROM with files installed

The test script tests devices in the following order:
1. Memory tests (one pass)
2.

Read-only tests: DK* disks, DR* disks, DQ* disks, MK* tapes, DV* floppy.

NOTE: You must install media to test disks, tapes, and the floppy drive. Since
no write tests are performed, it is safe to test disks and tapes that
contain data.
3.

Console loopback tests if -lb argument is specified: COM2 serial port and
parallel port.

VGA console tests: These tests are run only if the console environment
variable is set to serial. The VGA console test displays rows of the word
compaq.

Network internal loopback tests for EW* networks.

Error Log Analysis with Compaq Analyze

Compaq Analyze (CA) is a fault management diagnostic tool that is
used to determine the cause of hardware failures. Compaq Analyze
performs system diagnostic processing of both single and multiple
error/fault events.
Compaq Analyze may or may not be installed on the customer's system with the
operating system, depending on the release cycle. If CA is installed, the Compaq
Analyze Director starts automatically as part of the system start-up. CA
provides automatic background analysis. When an error event occurs, it
triggers the firing of an analysis rule. The analysis engine collects and
processes the information and typically generates a “problem found” report, if
appropriate. The report can be automatically sent to users on a notification
mailing list and, if DSNlink is installed, a call can be logged with the customer
support center.
Compaq Analyze has the capability to support the Tru64 UNIX and OpenVMS
operating systems on Alpha platforms.

NOTE: Compaq Analyze is a successor tool to DECevent and typically does not
support the same systems as DECevent.

ES45 Service Guide

UNIX Indictment
For each CPU indictment that is sent to the operating system a callout report is
generated. After the bad component is replaced the following commands must
be executed to bring the new components on-line for use. The following is an
example of using the Indictment command.
#hwmgr –status comp -ngood

NOTE: The indicted problem state attached to the previous component is still in
effect even though a new component may have been inserted. Use the
command “ hwmgr –unindict –id <hwid> ” to clear the problem
state when the component is operating properly.
The following is an example of a CPU unindict command.
#hwmgr –unindict –id 2
hwmgr:Unindict operation was successful

WEB Enterprise Service (WEBES) Director

Compaq Analyze uses the functionality contained in the WEBES
Director, a process that manages all other WEBES processes and
executes continuously on the machine when configured to do so. The
Director manages the decomposition processing of system error events,
provides required information to the analysis engine, and performs
notification message routing for the system. Compaq Analyze provides
the functionality for system event analysis and Bit-To-Text (BTT)
translation.
Compaq Analyze, includes common WEBES code. Subsequent releases of
Compaq Analyze will continue to ship with the common WEBES code.
The Director is started when the system is booted. Normally you do not need to
start the Director. If the Director has stopped running, restart it by following
the instructions in the WEBES Compaq Analyze User Guide documentation.
Compaq Analyze includes a graphical user interface (WUI) that allows the user
to interact with the Director. While only one Director process executes on the
machine at any time, many WUI processes can run at the same time, connected
to the single Director. Refer to the Compaq Analyze installation and user
manuals for the respective operating system to launch the Compaq Analyze
WUI. The Compaq service tools Web site available to customers is:
http://www.support.compaq.com/svctools
The applicable Compaq Analyze documentation includes the following:

Managed Entity
The Managed Entity designator includes the system host name (typically a
computer name for networking purposes), the type of computer system
(“Compaq AlphaServer ES45”), and the error event identification. The error
event identification uses new common event header Event_ID_Prefix and
Event_ID_Count components. The Event_ID_Prefix refers to an OS specific
identification for this event type. The Event_ID_Count indicates the number of
this event and the event type.
Service Obligation Data
Provides Obligation number and validity, system serial number, and company
name of service provider.
Brief Description
The Brief Description designator indicates whether the error event is related to
the CPU, system (PCI, storage, and so on), or environmental subsystem.

ES45 Service Guide

Callout ID
The last 12 characters of the Callout ID designator can be used to determine the
revision level of the analysis rule-set that is being used.
Full Description
The Full Description designator provides detailed error information, which can
include a description of the detected fault or error condition, the specific address
or data bit where this fault or error occurred, the probable FRU list, and service
related information.
FRU List
The FRU List designator lists the most probable defective FRUs. This list
indicates that one or more of these FRUs needs to be serviced. The information
typically includes the FRU probability, manufacturer, system device type,
system physical location, part number, serial number, and firmware revision
level (if applicable).

Fault Detection and Reporting

Table 5–2 provides a summary of the fault detection and correction
components of ES45 systems.
Generally, PALcode handles exceptions/interrupts as follows:
1. The PALcode determines the cause of the exception/interrupt.
2. If possible, it corrects the problem and passes control to the operating
system for error notification, reporting, and logging before returning the
system to normal operation.
If PALcode is unable to correct the problem, it
•

Logs double error halt error frames into the flash ROM

•

Logs uncorrectable error logout frames to the DPR

•

For single error halts, logs the uncorrectable logout frame into the DPR.

3. If error/event logging is required, control is passed through the OS
Privileged Architecture Library (PAL) handler. The operating system error
handler logs the error condition into the binary error log. Compaq Analyze
should then diagnose the error to the defective FRU.

Machine Checks/Interrupts

The exceptions that result from hardware system errors are called
machine checks/interrupts. They occur when a system error is detected
during the processing of a data request.
During the error-handling process, errors are first handled by the appropriate
PALcode error routine and then by the associated operating system error
handler. PALcode transfers control to the operating system through the PAL
handler.
Table 5–3 lists the machine checks/interrupts that are related to error events.
The designations — 630, 670, 620, 660, and 680 — indicate a system control
block (SCB) offset to the fatal system error handler for Tru64 UNIX and
OpenVMS.

Error Logging and Event Log Entry Format

The operating system error handlers generate several entry types.
Entries can be of variable length based on the number of registers
within the entry.
Each entry consists of an operating system header, several device frames, and
an end frame. Most entries have a PAL-generated logout frame, and may
contain frames for CPU, memory, and I/O.
Table 5–4 shows an event structure map for a system uncorrectable PCI target
abort error.

following topics are covered:
•

System Consoles

•

Displaying the Hardware Configuration

•

Setting Environment Variables

•

Setting Automatic Booting

•

Changing the Default Boot Device

System Configuration and Setup 6-1

6.1

System Consoles

The SRM console program is located in a flash ROM on the system
motherboard. From the console interface, you can set up and boot the
operating system, display the system configuration, and run
diagnostics. For complete information, see the ES45 Owner’s Guide.

SRM Console
Systems running the Tru64 UNIX or OpenVMS operating systems are
configured from the SRM console, a command-line interface (CLI). From the
CLI you can enter commands to configure the system, view the system
configuration, boot the system, and run ROM-based diagnostics.
NOTE: The operating systems use different algorithms for system time. If you
switch between operating systems (for example, between UNIX and
OpenVMS), be sure to reset the time at the operating system level.
Linux
The procedure for installing Linux on an Alpha system is described in the Alpha
Linux installation document for your Linux distribution. The installation
document can be downloaded from the following Web site:
http://www.compaq.com/alphaserver/linux
RMC CLI
The remote management console (RMC) provides a command-line interface
(CLI) for controlling the system. You can use the CLI either locally or remotely
(modem connection) to power the system on and off, halt or reset the system,
and monitor the system environment. You can also use the dump, env, and
status commands to help diagnose errors. See Chapter 7 for details.

6-2 ES45 Service Guide

6.1.1

Selecting the Display Device

The SRM console environment variable determines to which display
device (VT-type terminal or VGA monitor) the console display is sent.
The console terminal that displays the SRM user interface can be either a serial
terminal (VT320 or higher, or equivalent) or a VGA monitor.
The SRM console environment variable determines the display device.
•

If console is set to serial, and a VT-type device is connected, the SRM
console powers on in serial mode and sends power-up information to the VT
device. The VT device can be connected to the MMJ port or to COM2.

•

If console is set to graphics, the SRM console expects to find a VGA card
and, if so, displays power-up information on the VGA monitor after VGA
initialization has been completed.

You can verify the display device with the SRM show console command and
change the display device with the SRM set console command. If you change
the display device setting, you must reset the system (with the Reset button or
the init command) to put the new setting into effect.
In the following example, the user displays the current console device (a
graphics device) and then resets it to a serial device. After the system
initializes, output will be displayed on the serial terminal.
P00>>> show console
console
graphics
P00>>> set console serial
P00>>> init
.
.
.

System Configuration and Setup 6-3

6.1.2

Setting the Control Panel Message

You can create a customized message to be displayed on the operator
control panel after startup self-tests and diagnostics have been
completed.
When the operating system is running, the control panel displays the console
revision. It is useful to create a customized message if you have a number of
systems and you want to identify each system by a node name.
You can use the SRM set ocp_text command to change this message (see
Example 6–1). The message can be up to 16 characters and must be entered in
quotation marks.

Example 6–1 set ocp_text
P00>>> set ocp_text “Node Alpha1”

6-4 ES45 Service Guide

6.2

Displaying the Hardware Configuration

View the system hardware configuration by entering commands from
the SRM console. It is useful to view the hardware configuration to
ensure that the system recognizes all devices, memory configuration,
and network connections.
Use the following SRM console commands to view the system configuration.
See the Owner’s Guide for details.
show boot*

Displays the boot environment variables.

show config

Displays the logical configuration of interconnects and buses
on the system and the devices found on them.

show device

Displays the bootable devices and controllers in the system.

show fru

Displays the physical configuration of FRUs (field-replaceable
units).

show memory

Displays configuration of main memory.

System Configuration and Setup 6-5

6.3

Setting Environment Variables

Environment variables pass configuration information between the
console and the operating system. Their settings determine how the
system powers up, boots the operating system, and operates.
•

To check the setting for a specific environment variable, enter the show
envar command, where the name of the environment variable is
substituted for envar.

•

To reset an environment variable, use the set envar command, where the
name of the environment variable is substituted for envar.

6-6 ES45 Service Guide

set envar
The set command sets or modifies the value of an environment variable. It can
also be used to create a new environment variable if the name used is unique.
Environment variables pass configuration information between the console and
the operating system. Their settings determine how the system powers up,
boots the operating system, and operates. The syntax is:
set envar value
envar

The name of the environment variable to be modified.

value

The new value of the environment variable.

New values for the following environment variables take effect only after you
reset the system by pressing the Reset button or issuing the init command.
auto_action
console
cpu_enabled
os_type
pk*0_fast
pk*0_host_id
pk*0_soft_term
console_memory_allocation
show envar
The show envar command displays the current value (or setting) of an
environment variable. The syntax is:
show envar
envar

The name of the environment variable to be displayed. The
wildcard * displays all environment variables.

SRM into secure mode.

pci_parity

Disable or enable parity checking on the PCI bus.
On—PCI parity enabled (default value)
Off—PCI parity disabled
Some PCI devices do not implement PCI parity
checking, and some have a parity-generating
scheme in which the parity is sometimes incorrect
or is not fully compliant with the PCI specification. In such cases, the device functions properly
so long as parity is not checked.

pk*0_fast

Enables fast SCSI devices on a SCSI controller to
perform in standard or fast mode.
0—Sets the default speed for devices on the
controller to standard SCSI. If a controller is set
to standard SCSI mode, both standard and fast
SCSI devices will perform in standard mode.
1—Sets the default speed for devices on the
controller to fast SCSI mode.
Devices on a controller that connects to both
standard and Fast SCSI devices will
automatically perform at the appropriate rate for
the device, either fast or standard mode.

Variable

Attribute

Description

pk*0_host_id

Sets the controller host bus node ID to a value
between 0 and 7.
0 to 7—Assigns bus node ID for specified host
adapter.

pk*0_soft_term

Enables or disables SCSI terminators for optional
SCSI controllers. This environment variable
applies to systems using the Qlogic SCSI
controller, though it does not affect the onboard
controller.
The Qlogic SCSI controller implements the 16-bit
wide SCSI bus. The Qlogic module has two
terminators, one for the 8 low bits and one for the
high 8 bits. There are five possible values:
off—Turns off both low 8 bits and high 8 bits.
Low—Turns on low 8 bits and turns off high 8
bits.
High—Turns on high 8 bits and turns off low 8
bits.
On—Turns on both low 8 bits and high 8 bits.

sys_serial_num

Sets the system serial number, which is then
propagated to all FRUs that have EEPROMs.
The serial number can be read by the operating
system.

tt_allow_login

Enables or disables login to the SRM console
firmware on alternative console ports.
0—Disables login on alternative console ports.
1—Enables login on alternative console ports
(default setting).
If the console output device is set to serial, set
tt_allow_login 1 allows you to log in on the
primary COM1(MMJ) port, or alternate COM2
port, or the VGA monitor.
If the console output device is set to graphics,
set tt_allow_login 1 allows you to log in through
either the COM1(MMJ) or COM2 console port.

System Configuration and Setup 6-15

6.4

Setting Automatic Booting

Tru64 UNIX and OpenVMS systems are factory set to halt in the SRM
console. You can change these defaults, if desired.
Systems can boot automatically (if set to autoboot) from the default boot device
under the following conditions:
•

When you first turn on system power

•

When you power cycle or reset the system

•

When system power comes on after a power failure

•

After a bugcheck (OpenVMS) or panic (Linux or Tru64 UNIX)

6.4.1

Setting the Operating System to Auto Start

The SRM auto_action environment variable determines the default
action the system takes when the system is power cycled, reset, or
experiences a failure.
The factory setting for auto_action is halt. The halt setting causes the system
to stop in the SRM console. You must then boot the operating system manually.
For maximum system availability, auto_action can be set to boot or restart.
•

With the boot setting, the operating system boots automatically after the
SRM init command is issued or the Reset button is pressed.

•

With the restart setting, the operating system boots automatically after the
SRM init command is issued or the Reset button is pressed, and it also
reboots after an operating system crash.

To set the default action to boot, enter the following SRM commands:
P00>>> set auto_action boot
P00>>> init
See the Owner’s Guide for more information.

6-16 ES45 Service Guide

6.5

Changing the Default Boot Device

You can change the default boot device with the set bootdef_dev
command.
You can designate a default boot device. You change the default boot device by
using the set bootdef_dev SRM console command. For example, to set the
boot device to the IDE CD-ROM, enter commands similar to the following:
P00>>> show bootdef_dev
bootdef_dev
dka400.4.0.1.1
P00>>> set bootdef_dev dqa500.5.0.1.1
P00>>> show bootdef_dev
bootdef_dev dqa500.5.0.1.1

See the Owner’s Guide for more information.

System Configuration and Setup 6-17

6.6

Setting SRM Security

The set password and set secure commands set SRM security. The
login command turns off security for the current session. The clear
password command returns the system to user mode.
The SRM console has two modes, user mode and secure mode.
•

User mode allows you to use all SRM console commands. User mode is the
default mode.

•

Secure mode allows you to use only the boot and continue commands. The
boot command cannot take command-line parameters when the console is
in secure mode. The console boots the operating system using the environment variables stored in NVRAM (boot_file, bootdef_dev, boot_flags).

Example 6–2 Set Password
P00>>> set password
Please enter the password:
Please enter the password again:
P00>>>
P00>>> set password
Please enter the password:
Please enter the password again:
Now enter the old password:
P00>>>
P00>>> set password
Please enter the password:
Password length must be between 15 and 30 characters
P00>>>

Setting a password. If a password has not been set and the set password
command is issued, the console prompts for a password and verification.
The password and verification are not echoed.

Changing a password. If a password has been set and the set password

command is issued, the console prompts for the new password and verification, then prompts for the old password. The password is not changed if the
validation password entered does not match the existing password stored in
NVRAM.

6-18 ES45 Service Guide

The password length must be between 15 and 30 alphanumeric characters.
Any characters entered after the 30th character are not stored.

Example 6–3 set secure
P00>>> set secure
Console is secure. Please login.
P00>>> login
Please enter the password:
P00>>> b dkb0

The set secure command console puts the console into secure mode. A

password must be set before you can issue set secure. Once the console is
secure, only the boot and continue commands can be used. The boot
command cannot take command-line parameters.

Entering the login command turns off security features for the current

console session. This allows the operator to enter any SRM command—in
this case, a boot command with command-line parameters.

Example 6–4 clear password
P00>>> clear password
Please enter the password:
Password successfully cleared.
P00>>>

Clearing the password returns the system to user mode.
If You Forget the Password
If you forget the current password, use the login command in conjunction with
the control panel Halt button to clear the password, as follows:
1. Enter the login command:
P00>>> login

2. When prompted for the password, press the Halt button to the latched
position and then press the Return (or Enter) key.
3. Press the Halt button to release the halt. The password is now cleared and
the console cannot be put into secure mode unless you set a new password.

Memory Configuration

Become familiar with the rules for memory configuration before
adding DIMMs to the system.
Refer to Figure 6–4 or Figure 6–5 and observe the following rules for installing
DIMMs.
•

You can install up to 16 DIMMs or up to 32 DIMMs.

•

An option consists of a set of 4 DIMMs. You must install all 4 DIMMs to
populate a set.

•

Fill sets in numerical order. Populate all 4 slots in Set 0, then populate Set
1, and so on.

•

An “array” is one set for systems that support 16 DIMMs and two sets for
systems that support 32 DIMMs.

•

DIMMs in an array must be the same capacity and type. For example,
suppose you have populated Sets 0, 1, 2, and 3. When you populate Set 4,
the DIMMs must be the same capacity and type as those installed in Set 0.
Similarly, Set 5 must be populated with DIMMs of the same capacity and
type as are in Set 1, and so on, as indicated in the following table.

System Configuration and Setup 6-23

DIMM Information for Two System Types
DIMMs are manufactured with two types of SRAMs, stacked and unstacked
(see Figure 6–3). Stacked DIMMs provide twice the capacity of unstacked
DIMMs, and, at the time of shipment, are the highest capacity DIMMs offered
by Compaq. The system may have either stacked or unstacked DIMMs.
A memory option consists of a “set” of four DIMMs. The system supports two
sets per “array” and four arrays per system. You can mix stacked and
unstacked DIMMs within the system, but not within an array. The DIMMs
within an array must be of the same capacity and type (stacked or unstacked)
because of different memory addressing.
When installing sets 0, 1, 2, and 3, an incorrect mix will not occur. When
installing sets 4, 5, 6, or 7, however, you must ensure that the four DIMMs
being installed match the capacity and type of DIMMs in the existing array. If
necessary, rearrange DIMMs for proper configuration.

Memory Performance Considerations
Interleaved operations reduce the average latency and increase the memory
throughput over non-interleaved operations. With one memory option
(4 DIMMs) installed, memory interleaving will not occur. For 2-way
interleaving, array 0 & 2 and 1 & 3 must have the same size memory. For 4-way
interleaving, array 0 through 3 must have the same size memory.
The output of the show memory command provides the memory interleaving
status of the system.

The show memory display does not indicate the number of DIMMs or their
size. Array 3 could consist of two sets of 128 MB DIMMs (eight DIMMs) or one
set of 256 MB DIMMs (four DIMMs). Either combination provides 1024 MB of
memory.
For optimum memory utilization and performance, load memory arrays in the
following order: 0, 1, 2, 3, 4, 6, 5, and 7. See Figure 6–4 for array locations.

System Configuration and Setup 6-29

The PCI slots are split across four independent 64-bit PCI buses, three buses at
66 MHz and one bus at 33 MHz. These buses correspond to Hose 0 through
Hose 3 in the system logical configuration. The slots on each bus are listed
below.
Some PCI options require drivers to be installed and configured. These options
come with a floppy or a CD-ROM. Refer to the installation document that came
with the option and follow the manufacturer's instructions.
There is no direct correspondence between the physical numbers of the slots
on the I/O backplane and the logical slot identification reported with the SRM

The procedure for installing Linux on an Alpha system is described in the Alpha
Linux installation document for your Linux distribution. The installation
document can be downloaded from the following Web site:
http://www.compaq.com/alphaserver/linux
You need V5.6-3 or higher of the SRM console to install Linux. If you have a
lower version of the firmware, you will need to upgrade. For instructions and
the latest firmware images, see the following URL.

Using the Remote
Management Console

You can manage the system through the remote management console (RMC).
The RMC is implemented through an independent microprocessor that resides
on the system motherboard. The RMC also provides access to the repository for
all error information in the system.
This chapter explains the operation and use of the RMC. Sections are:
•

RMC Overview

•

Operating Modes

•

Terminal Setup

•

Connecting to the RMC CLI

•

Using the Remote Management Console

7-1

7.1

RMC Overview

The remote management console provides a mechanism for monitoring
the system (voltages, temperatures, and fans) and manipulating it on a
low level (reset, power on/off, halt). It also provides functionality to
read and write configuration and error log information to FRU error
log devices.
The RMC performs monitoring and control functions to ensure the successful
operation of the system.
•

Monitors thermal sensors on the CPUs, the PCI backplane, and the power
supplies

•

Monitors voltages, power supplies, and fans

•

Handles hot swap of power supplies and fans

•

Controls the operator control panel (OCP) display and writes status
messages on the display

•

Detects alert conditions such as excessive temperature, fan failure, and
power supply failure. On detection, RMC displays messages on the OCP,
pages an operator, and sends an interrupt to SRM, which then passes the
interrupt to the operating system or an application.

•

Shuts down the system if any fatal conditions exist. For example:

The temperature reaches the failure limit.
 The cover to the system card cage is removed.
 The main fan (Fan 6) and the redundant fan (Fan 5) fail.
•

Retrieves and passes information about a system shutdown to SRM at the
next power-up. SRM displays a message regarding the last shutdown.

•

Provides a command-line interface (CLI) for the user to control the system.
From the CLI you can power the system on and off, halt or reset the system,
and monitor the system environment.

•

Passes error log information to the DPR so that this information can be
accessed by the system.

Retrieves information from the DPR and stores it in FRU EEROMs.

ES45 Service Guide

The RMC logic is implemented using an 8-bit microprocessor, PIC17C44, as the
primary control device. The firmware code is resident within the microprocessor and in flash memory. If the RMC firmware should ever become corrupted or
obsolete, you can update it manually using the Loadable Firmware Update
Utility. See Chapter 3 for details. The microprocessor can also communicate
with the system power control logic to turn on or turn off power to the rest of
the system.
The RMC is powered by an auxiliary 5V supply. You can gain access to the
RMC as long as AC power is available to the system (through an AC outlet).
Thus, if the system fails, you can still access the RMC and gather error/fault
information about the failure.

DPR Error Repository
The RMC manages an extensive network of FRU I2C EEPROMs. Information
from these EEPROMs is stored in dual-port RAM (DPR)—a shared RAM that
facilitates interaction between the RMC and the system—and can be accessed to
diagnose hardware failures.
At system power-up, the RMC reads 256 bytes of data from each FRU EEPROM
and stores it in the DPR. The EEPROM data contains information on
configuration and errors. The data is accessible through the TIG chip on the
system motherboard.
As one of its functions, the TIG provides interfaces for the firmware and the
operating system to communicate with the server management logic. The data
accessed from DPR provides configuration information to the firmware during
start-up. Remote or local applications can read the DPR system error and
configuration repository. The error log information is written to the DPR by an
error handling agent and then written back to the EEPROMs by the RMC. This
arrangement ensures that the error log is available on a FRU after power has
been lost.
The RMC console provides several commands for accessing error information in
the DPR. See Section 7.6. Compaq Analyze, described in Chapter 5, can access
the FRU EEPROM error logs to provide diagnostic information for system
FRUs.

Operating Modes

The RMC can be configured to manage different data flow paths
defined by the com1_mode environment variable. In Through mode
(the default), all data and control signals flow from the system COM1
port through the RMC to the active external port. You can also set
bypass modes so that the signals partially or completely bypass the
RMC. The com1_mode environment variable can be set from either
SRM or the RMC. See Section 7.6.1.

ES45 Service Guide

Through Mode
Through mode is the default operating mode. The RMC routes every character
of data between the internal system COM1 port and the active external port,
either the local COM1 serial port (MMJ) or the 9-pin modem port. If a modem
is connected, the data goes to the modem. The RMC filters the data for a
specific escape sequence. If it detects the escape sequence, it connects to the
RMC CLI.
Figure 7–1 illustrates the data flow in Through mode. The internal system
COM1 port is connected to one port of the DUART chip, and the other port is
connected to a 9-pin external modem port, providing full modem controls. The
DUART is controlled by the RMC microprocessor, which moves characters
between the two UART ports. The local MMJ port is always connected to the
internal UART of the microprocessor. The escape sequence signals the RMC to
connect to the CLI. Data issued from the CLI is transmitted between the RMC
microprocessor and the active port that connects to the RMC CLI.

NOTE: The internal system COM1 port should not be confused with the
external COM1 serial port on the back of the system. The internal
COM1 port is used by the system software to send data either to the
COM1 port on the system or to the RMC modem port if a modem is
connected.

Local Mode
You can set a Local mode in which only the local channel can communicate with
the system COM1 port. In Local mode the modem is prevented from sending
characters to the system COM1 port, but you can still connect to the RMC CLI
from the modem.

Using the Remote Management Console

Bypass Modes

For modem connection, you can set the operating mode so that data
and control signals partially or completely bypass the RMC. The
bypass modes are Snoop, Soft Bypass, and Firm Bypass.

Figure 7–2 shows the data flow in the bypass modes. Note that the internal
system COM1 port is connected directly to the modem port.
NOTE: You can connect a serial terminal to the modem port in any of the
bypass modes.
The local terminal is still connected to the RMC and can still connect to the
RMC CLI to switch the COM1 mode if necessary.
Snoop Mode
In Snoop mode data partially bypasses the RMC. The data and control signals
are routed directly between the system COM1 port and the external modem
port, but the RMC taps into the data lines and listens passively for the RMC
escape sequence. If it detects the escape sequence, it connects to the RMC CLI.
The escape sequence is also passed to the system on the bypassed data lines. If
you decide to change the default escape sequence, be sure to choose a unique
sequence so that the system software does not interpret characters intended for
the RMC.
In Snoop mode the RMC is responsible for configuring the modem for dial-in as
well as dial-out alerts and for monitoring the modem connectivity.
Because data passes directly between the two UART ports, Snoop mode is
useful when you want to monitor the system but also ensure optimum COM1
performance.
Soft Bypass Mode
In Soft Bypass mode all data and control signals are routed directly between the
system COM1 port and the external modem port, and the RMC does not listen
to the traffic on the COM1 data lines. The RMC is responsible for configuring
the modem and monitoring the modem connectivity. If the RMC detects loss of
carrier or the system loses power, it switches automatically into Snoop mode. If
you have set up the dial-out alert feature, the RMC pages the operator if an
alert is detected and the modem line is not in use.
Soft Bypass mode is useful if management applications need the COM1 channel
to perform a binary download, because it ensures that RMC does not
accidentally interpret some binary data as the escape sequence.

Using the Remote Management Console

7-7

After downloading binary files, you can set the com1_mode environment
variable from the SRM console to switch back to Snoop mode or other modes for
accessing the RMC, or you can hang up the current modem session and
reconnect it.
Firm Bypass Mode
In Firm Bypass mode all data and control signals are routed directly between
the system COM1 port and the external modem port. The RMC does not
configure or monitor the modem. Firm Bypass mode is useful if you want the
system, not the RMC, to fully control the modem port and you want to disable
RMC remote management features such as remote dial-in and dial-out alert.
You can switch to other modes by resetting the com1_mode environment
variable from the SRM console, but you must then set up the RMC again from
the local terminal.

Connecting to the RMC CLI

You type an escape sequence to connect to the RMC CLI. You can
connect to the CLI from any of the following: a modem, the local serial
console terminal, the local VGA monitor, or the system. The “system”
includes the operating system, SRM, or an application.
•

You can connect to the RMC CLI from the local terminal regardless of the
current operating mode.

•

You can connect to the RMC CLI from the modem if the RMC is in Through
mode, Snoop mode, or Local mode. In Snoop mode the escape sequence is
passed to the system and displayed.

NOTE: Only one RMC CLI session can be active at a time.
Connecting from a Serial Terminal
Invoke the RMC CLI from a serial terminal by typing the following default
escape sequence:
^[^[ rmc
This sequence is equivalent to typing Ctrl/left bracket, Ctrl/left bracket, rmc.
On some keyboards, the Esc key functions like the Ctrl/left bracket combination.
To exit, enter the quit command. This action returns you to whatever you
were doing before you invoked the RMC CLI. In the following example, the
quit command returns you to the system COM1 port.
RMC> quit
Returning to COM port

Power On and Off, Reset, and Halt

The RMC power {on, off}, halt {in, out}, and reset commands perform
the same functions as the buttons on the operator control panel.

Power On and Power Off
The RMC power on command powers the system on, and the power off
command powers the system off. The Power button on the OCP, however, has
precedence.
•

If the system has been powered off with the Power button, the RMC cannot
power the system on. If you enter the power on command, the message
“Power button is OFF” is displayed, indicating that the command will have
no effect.

•

If the system has been powered on with the Power button, and the power
off command is used to turn the system off, you can toggle the Power
button to power the system back on.

When you issue the power on command, the terminal exits RMC and
reconnects to the server’s COM1 port.

Example 7–5 power on/off
RMC> power on
Returning to COM port
RMC> power off

ES45 Service Guide

Halt In and Halt Out
The halt in command halts the system. The halt out command releases the
halt. When you issue either the halt in or halt out command, the terminal
exits RMC and reconnects to the server's COM1 port.

Example 7–6 halt in/out
RMC> halt in
Returning to COM port
RMC> halt out

The halt out command cannot release the halt if the Halt button is latched in.
If you enter the halt out command, the message “Halt button is IN” is
displayed, indicating that the command will have no effect. Toggling the Power
button on the operator control panel overrides the halt in condition.

Configuring Dial-Out Alert

When you are not monitoring the system from a modem connection,
you can use the RMC dial-out alert feature to remain informed of
system status. If dial-out alert is enabled, and the RMC detects alarm
conditions within the managed system, it can call a preset pager
number.
You must configure remote dial-in for the dial-out feature to be enabled. See
Section 7.6.6.
To set up the dial-out alert feature, connect to the RMC CLI from the local
serial terminal or local VGA monitor.

Example 7–9 Dial-Out Alert Configuration
RMC> set dial
Dial String: ATXDT9,15085553333
RMC> set alert
Alert String: ,,,,,,5085553332#;
RMC> enable alert
RMC> clear alert
RMC> send alert
Alert detected!
RMC> clear alert
RMC> status
.
.
Alert Enable: Enabled
.

.
A typical alert situation might be as follows:
•

The RMC detects an alarm condition, such as over temperature warning.

•

The RMC dials your pager and sends a message identifying the system.

•

You dial the system from a remote serial terminal.

•

You connect to the RMC CLI, check system status with the env command,
and, if the situation requires, power down the managed system.

•

When the problem is resolved, you power up and reboot the system.

 Clears any alert that may be pending. This ensures that the send alert
command will generate an alert condition.
 Forces an alert condition. This command is used to test the setup of the

dial-out alert function. It should be issued from the local serial terminal or
local VGA monitor. As long as no one connects to the modem and there is
no alert pending, the alert will be sent to the pager immediately. If the
pager does not receive the alert, re-check your setup.

Clears the current alert so that the RMC can capture a new alert. The last
alert is stored until a new event overwrites it. The Alert Pending field of
the status command becomes NO after the alert is cleared.

Verifies the settings. Check that the Alert Enable field is set to Enabled.
NOTE: If you do not want dial-out paging enabled at this time, enter the
disable alert command after you have tested the dial-out alert
function. Alerts continue to be logged, but no paging occurs.

Resetting the Escape Sequence

The RMC set escape command sets a new escape sequence.
The new escape sequence can be any character string, not to exceed 14
characters. A typical sequence consists of two or more control characters. It is
recommended that control characters be used in preference to ASCII characters.
Use the status command to verify the new escape sequence before exiting the
RMC.
The following example consists of two instances of the Esc key and the letters
“FUN.” The “F” is not displayed when you set the sequence because it is
preceded by the escape character. Enter the status command to see the new
escape sequence.

Example 7–10 set escape
RMC> set escape
Escape Sequence: un
RMC> status
.
.
.
Escape Sequence: ^[^[FUN

CAUTION: Be sure to record the new escape sequence. Restoring the default
sequence requires moving a jumper on the system motherboard.

RMC will not answer
when modem is called.
(continued from
previous page)

On AC power-up,
RMC defers
initializing the modem
for 30 seconds to allow
the modem to
complete its internal
diagnostics and
initializations.

Wait 30 seconds after
powering up the system and
RMC before attempting to
dial in.

After the system is
powered up, the COM1
port seems to hang or
you seem to be unable
to execute RMC
commands.

There is a normal
delay while the RMC
completes the system
power-on sequence.

Wait about 40 seconds.

New escape sequence

RMC console must be reset to
factory defaults.

During a remote
connection, you see a
“+++” string on the
screen.

The modem is
confirming whether
the modem has really
lost carrier. This is
normal behavior.

The message
“unknown command”
is displayed when you
enter a carriage return

FRU Removal
and Replacement

This chapter describes the procedures for removing and replacing FRUs on
ES45 systems.
Unless otherwise specified, install a FRU by reversing the steps shown in the
removal procedures.

WARNING: To prevent injury, access is limited to persons who
have appropriate technical training and experience. Such persons are expected to understand the hazards of working within
this equipment and take measures to minimize danger to themselves or others. These measures include:
1. Remove any jewelry that may conduct electricity.
2. If accessing the system card cage, power down the system and
wait 2 minutes to allow components to cool.
3. Wear an anti-static wrist strap when handling internal components.

NOTE: If you are installing or replacing CPU cards, memory DIMMs, or PCI
cards, become familiar with the location of the card slots and configuration rules. See Chapter 6.

CAUTION: Static electricity can damage integrated circuits. Always use a
grounded wrist strap (29-26246) and grounded work surface when
working with internal parts of a computer system.
Remove jewelry before working on internal parts of the system.

IMPORTANT!

8-2

After you have replaced FRUs and determined that the
system has been restored to its normal operating condition, you must clear the system error information repository (error information logged to the DPR). Use the
clear_error all command to clear all errors logged in
the FRU EEPROMs and to initialize the central error
repository. See Section 4.4 for details on clear_error.

8.10 Memory DIMMs
DIMMs are manufactured with two types of SRAMs, stacked and unstacked.
Stacked DIMMs provide twice the capacity of unstacked DIMMs and, at the
time of shipment, are the highest capacity DIMMs offered by Compaq. Your
system may have either stacked or unstacked DIMMs.
A memory option consists of a “set” of four DIMMs. The system supports two
sets per “array” and four arrays per system. You can mix stacked and unstacked DIMMs within the system, but not within an array. The DIMMs within
an array must be of the same capacity and type (stacked or unstacked) because
of different memory addressing.
When installing sets 0, 1, 2, and 3, an incorrect mix will not occur. When installing sets 4, 5, 6, or 7, however, you must ensure that the four DIMMs being installed match the type of DIMMs in the existing array. If necessary, rearrange
DIMMs for proper configuration.
Only the following DIMMs and DIMM options can be used in the ES45 system.

Setting Jumpers

Review the material in the previous sections of this appendix before
setting any system jumpers. First, shut down the system and remove
the power cord from each power supply.

Setting Jumpers
1. Shut down the operating system.
2. Shut down power on all external options connected to the system.
3. Turn off power to the system.
4. Unplug the power cord from each power supply and wait for all LEDs to
turn off.
5. Remove enclosure panels and chassis covers to gain access to the system
motherboard or PCI board.
•

If you are setting RMC jumpers, remove CPU 1 to gain access to the
jumpers.

•

If you are setting TIG/SROM jumpers, remove MMB 1 to gain access to
the jumpers.

•

If you are setting PCI jumpers, you typically do not need to remove any
PCI cards. However, if you have a full-length card in slot 10, remove it.

6. Locate the jumper you need to set. Refer to the illustrations in this
appendix. Set the jumpers as needed.
7. Reinstall any modules you removed.
8. Reinstall the chassis covers and enclosure panels.
9. Plug the power cords into the supplies.

DPR Address Layout

This appendix shows the address layout of the dual-port RAM (DPR). Use the
SRM examine dpr:address command (where address is the offset from the
base of the DPR) or use the RMC dump command to view locations in the DPR.
See Appendix D for definitions of locations written when environmental error
events occur.

Instead, these traps cause pipeline redirection and can
be distinguished by examining the PMPC value for the
presence of the corresponding PAL-code entry offset

Interrupt Summary Register (ISUM)

The Interrupt Summary Register (ISUM) is a read-only register that
records all pending hardware, software, and AST interrupt requests
that have their corresponding enable bit set.
If a new interrupt (hardware, serial line, crd, or performance counters) occurs
simultaneously with an ISUM read, the ISUM read returns zeros. That
condition is normally assumed to be a passive release condition. The interrupt is
signaled again when the PALcode returns to native mode. The effects of this
condition can be minimized by reading ISUM twice and ORing the results.

VA_48 is clear, 43-bit virtual address format
is used, and when VA_48 is set, 48-bit
virtual address format is used. The effect of
this bit on the IVA_FORM register is
identical to the effect of VA_CTL<VA_48>
on the VA_FORM register.
When VA_48 is set, the sign extension
checkers generate an ACV if va<63:0> ≠
SEXT(va<47:0>). When VA_48 is clear, the
sign extension checkers generate an ACV if
va<63:0> ≠ SEXT(va<42:0>).
This bit also affects DTB_DOUBLE Traps. If

D.11 21274 Cchip Miscellaneous Register (MISC)
This register is designed so that there are no read side effects, and that
writing a 0 to any bit has no effect. Therefore, when software wants to
write a 1 to any bit in the register, it need not be concerned with readmodify-write or the status of any other bits in the register. Once NXM
is set, the NXS field is locked so that initial NXM error information is
not overwritten by subsequent errors. It is unlocked when the software
clears the NXM CPU; however, writing it locks out the other CPU.
Writing a 1 to ACL (arbitration clear) clears both ABW bits and both
ABT (arbitration try) bits and unlocks the ABW field.

D.15 Pchip A/G PCI Error Register (GPERROR, APERROR)
This register is used for logging PCI errors on the GPCI or APCI buses
respectively.
The GPCI and APCI registers are identical. If any of bits <11:2> are set, then
this entire register is frozen and the Pchip output signal h_err is asserted. Only
bits <1:0> can be set after that. All other values will be held until bits <11:2, 0>
are clear. When an error is detected and one of bits <10:2> is set, the associated
cache block address, PCI command, and syndrome is captured in bits <55:52,
48:14> of this register. A monster window address has PCI address bit <40> set,
and this is reflected in A/G PERROR bit <48>. Likewise, a non-MWIN dual
address cycle (DAC) has PCI address bit <39> set, which shows up in A/G
PERROR bit <47>. Bits <46:14> of A/G PERROR contain the longword PCI
address bits <34:02> (a DAC could have bits set in PCI address bits <34:32>).
Bits <11:1> of this register are only set if the corresponding enable bits are set
in the PERREN register.

NOTE: Software must not perform back-to-back writes to this register. A write
to this register must be followed by a read from any PA-chip CSR, or a
write to any other CSR (except for the corresponding A/G PERRSET
register). Back-to-back writes will yield unpredictable results.

D.17 DPR Registers for 680 Correctable Machine
Check Logout Frames
DPR Locations A0:A9 represent the information that the console will
read when a 680 machine check logout frame is loaded. They provide
the interrupt information obtained by the RMC through the LM78
sensors. When an error occurs, the RMC writes the bits and delivers an
IRQ to the SRM console. The SRM reads the bits and clears them. On
the next 680 error, the RMC writes the error into the A0:A9 locations.

Appendix E
Isolating Failing DIMMs

This appendix explains how to manually isolate a failing DIMM from the failing
address and failing data bits. It also covers how to isolate single-bit errors. The
following topics are covered:
•

Information for Isolating Failures

•

DIMM Isolation Procedure

•

EV68 Single-Bit Errors

Isolating Failing DIMMs

E-1

E.1

Information for Isolating Failures

Table E–1 lists the information needed to isolate the failure. See
Appendix D for the register table for the Array Address Registers
(AARs). The failing address and failing data can come from a variety of
different locations such as the SROM serial line, SRM screen displays,
the SRM event log, and errors detected by the 21264 (EV68) chip.
Convert the address to data bits if the address is not on a 256-bit alignment
(address ends in a value less than 20 or address xxxxx20 or address xxxxxnn,
where nn is 1 through 1F). For example, using failing address 0x1004 and
failing data bit 8(dec), first multiply the failing address 4 by 8 = 32. Then add
32 to the failing data bit to yield the actual failing data bit 40. This conversion
yields the new failing information to be failing address 0x1000 and failing data
bit = 40(dec).

E.2

DIMM Isolation Procedure

Use the procedure in this section to isolate the failing DIMM.
1.

Find the failing array by using the failing address and the Array Address
Registers (AARs—see Appendix D). Use the AAR base address and size to
create an Address range for comparing the failing address.
For example, if AAR1 base address was 40000000 (1 GB) and its size was
10000000 (256 MB), the address range would be 40000000–4FFFFFFF
(4–4.25 GB). This range would be used to compare against the failing
address.

Determine if the Address XORing is enabled.
•

If Address XORING is enabled, use Table E–2 to find the real array on
which the failure occurred for 4-way interleaving, or Error! Reference
source not found. for 2-way interleaving.

•

If Bit 51 of the CSC register is set to 1, XORing is disabled.

D&F

Now that you have the real array, the failing Data/Check bits, and the
correct set, use Table E–5 to find the failing DIMM or DIMMs.

The table shows data bits 0–255 and check bits 0–31. These data bits indicate a
single-bit error. An SROM compare error would yield address and data bits
from 0–63. When you convert the address to be in the correct range, the failing
data would be somewhere between 0 and 255.

EV68 Single-Bit Errors

The procedure for detection down to the set of DIMMs for a single-bit
error is very similar to the procedure described in the previous
sections. However, you cannot isolate down to a specific data or check
bit.
The 21264 (EV68) chip detects and reports a C_ADDR<42:6> failing address
that is accurate to the cache block (64 bytes). The syndrome registers (Table E–
6) detect data syndrome information, providing isolation down to the low or high
quadword of the target octaword that the fault has been detected within. Each
of the syndrome registers is able to report 64 data bits (the quadword) and 8
check bits (memory data bus ECC bits).
Table E–6 shows the syndrome hexadecimal to physical data or check bit
decoding. For example, if you have an EV68 single-bit C_Syndrome_0 hexadecimal error value equal to 23, the second column indicates the decoded physical
data or check bit for this encoding. Use these physical data bits in conjunction
with the previously described isolation procedure to isolate the failing DIMMs.
