1.2 System Overview
Fault tolerance is the ability of a system to continue to provide computing
service despite the occurrence of single-point hardware failures.
The VAXft Model 810 system is the third generation in the VAXft family of
processors. The system achieves fault tolerance through its high levels of
availability. Table 1–1 describes these features.
Figure 1–1 shows the front view of the entry system. Figure 1–2 shows the front
view of the expanded system.

Introduction 1–1

Table 1–1 Availability Features
Feature

Description

Data Integrity
Dual rail internal bus

The module interconnect (MI) is a dual rail bus that allows
comparison of results at the end of each transmission.

Cyclic redundancy
check (CRC) and parity
checking

Device codes are appended to incoming data packets. This
ensures integrity when data is transferred within the system.

Self-checking checkers

On-line tests examine the checking mechanism logic for faults.

Computational Integrity
Duplicate CPUs

Two processor chips and associated logic are present on each
CPU module. The results of all computations are compared for
discrepancies.

Duplicate zones

Two CPUs are present in each zone. They compare results
with each other through the cross-link cable.

Fault Isolation and
Containment
Firewalls

Firewall chips are used on the I/O expansion module (EXM).
They interface with the MI bus. These chips perform error
checking, receive and send all data to the bus, and allow the
dual rail bus to act as a single rail bus.

System Availability

1–2 Introduction

Duplicate components

All components (zones, cables, peripherals, and enclosures) are
fully duplicated.

Automatic failover

Failover happens automatically, within microseconds of fault
detection.

Independent zones

Risk of service and operational errors is reduced because zones
are accessed independently. Each zone has a separate door.

1–4 Introduction

1.3 System Architecture
The system platform is based on a dual zone architecture. Each zone is
independent and is housed within a cabinet. The two zones communicate through
a cross-link cable.
The CPU pairs run in lockstep, executing the same commands at the same
time. A phase-lock loop ensures clock synchronization between zones. The
I/O attachment module (ATM) provides the console terminal interface and an
interface between the CPU and the ATM. The I/O interface modules connect to
the I/O bus in each zone to provide console terminal, network, and mass storage
interfaces.
Figure 1–3 shows the system architecture. Table 1–2 describes the components
shown in Figure 1–3.
Each zone contains the following components:
•

Logic card cage

•

Four memory motherboards (MMBs)

•

ATM with embedded I/O expansion module (EXM)

•

I/O interface module cage containing up to eight DSSI and Ethernet interface
modules

•

Power subsystem

•

Up to six 3.5-inch disks

•

CPU pair

•

Centerplane

1.4 Hardware
This section describes the hardware used with the system.

1.4.1 CPU and Memory Subsystem
The CPU module houses the CPU, cache memory, and main memory. The CPU
module contains two microprocessor chips operating at a 12-nanosecond cycle
time. Each of the microprocessor chips contains:
•

Error correction code (ECC)

•

An 8-Kbyte two-way set-associative data cache (P-cache)

•

A 2-Kbyte direct-mapped virtual instruction cache (I-cache)

•

An external secondary cache that contains a 512-Kbyte direct-mapped
write-back cache (B-cache)

Four MMBs plug into the CPU module. The 4-MB DRAM single inline memory
modules (SIMMs) plug into the MMBs. The system supports 32 MB to 256 MB of
memory.
The CPU module can read eight longwords (312 bits including ECC) at a time,
and can refresh the caches rapidly because memory access time is less than 200
nanoseconds.

1.4.2 I/O Subsystem
Each zone contains its own I/O, which is located in three types of modules:
•

DIM

•

EIM

•

ATM with embedded EXM

The DIMs connect to the system’s mass storage devices through the DSSI bus.
One DSSI bus is provided per DIM. One DIM takes up one node on the DSSI bus.
The EIM connects to the network devices in one of two ways: through a coaxial
cable connection that provides ThinWire Ethernet access, or through a 15-pin
connector that provides thickwire Ethernet access.
CPU and I/O components within a zone are connected through the system MI
bus, which is a 16-bit, dual rail, synchronous bus. The second rail is used for
error checking. The I/O subsystem is single rail bus with ECC embedded to
detect faults.

Introduction 1–13

1.4.5 Storage Devices
The system supports DSSI storage devices. To prevent a single point of failure,
the system is configured for dual access with shadowing to each storage device.
The DSSI cables are routed from one zone, to the storage devices, then to the
other zone. Each disk connects to both zones. Each zone connects to all disks.
The disks are available even when power to the logic modules is turned off. The
disks are not available when power to the zone is turned off or fails. Each disk
can be powered down individually.
A CPU module can access disks in the other zone through the DSSI connections
in its own zone or through the cross-link cable to the DSSI interface in the other
zone.
The system cabinet provides limited storage space — up to six optional RF35-HA
disks in each zone. The expander cabinet provides more storage space. Table 1–7
describes the storage devices supported by the expander cabinet.

1.5 Software
The system software consists of:
•

OpenVMS software

•

Fault Tolerant System Services (FTSS)

•

Volume shadowing

The VAXft Model 810 system runs with the OpenVMS VAX operating system,
Version 5.5-2HF.
FTSS provides the error handling required by fault tolerance. FTSS operation is
transparent to system users, layered OpenVMS software, and applications. FTSS
functions include:
•

Zone and device failover

•

Zone management

•

Event reporting and analysis

•

Zone synchronization

•

System service support routines

Volume shadowing is a layered software product that ensures uninterrupted
operation upon disk failures. It is essential to fault tolerant operation.

2.8 TF85C-BA Cartridge Tape Drive
The TF85C-BA cartridge tape drive serves as a system software load device.
It is housed in an enclosure, and comes with a DSSI controller module and an
interface module. The drive is a TK85 streaming tape drive that can store up
to 2.6 GB of data on a CompacTape III cartridge. The drive can read data from
a tape written by a TK70 or TK50 drive, but cannot overwrite a tape originally
written by a TK50.
The TF85C-BA cartridge tape drive accepts a TK cartridge that has a single-feed
reel. When a cartridge is inserted, the drive hooks the end of the tape and
threads it onto a takeup reel inside the drive. The tape must be completely
rewound and unloaded before the cartridge can be removed from the drive.
Rewinding and unloading may take up to 90 seconds.

Controls and Indicators 2–15

Figure 2–10 shows the front of the TF85C-BA cartridge tape drive. Table 2–7
summarizes the TF85C-BA cartridge tape drive controls and Table 2–8 describes

•

Do not drop or bang the cartridge. If the tape leader is displaced, the
cartridge is unusable and may cause damage to the drive.

•

Keep cartridges out of direct sunlight and away from heaters and other
sources of heat.

•

Store cartridges in a dust-free environment where the temperature is between
10°C and 38°C (50°F and 100°F) and the relative humidity is between 20%
and 80%.

•

If a cartridge has been exposed to extreme heat or cold, allow it to stabilize
at room temperature for the same amount of time it was exposed (up to 24
hours).

•

Do not place cartridges near sources of electromagnetic interference
(terminals, motors, video or X-ray equipment). Data on the tape may be
erased.

•

Place a label on a cartridge only in the label slot shown in Figure 2–11.

2.9.4 Inspecting the Tape Leader
If you have trouble loading a cartridge, inspect the tape leader and the drive
takeup leader.
Caution
Do not touch exposed portions of the magnetic tape. If the tape leader
is not in the correct position, do not try to use the cartridge. Use a new
cartridge instead.

You can use any one of the four console terminals (local or remote) for input
commands, but use only one terminal at a time. All of the console terminals echo
the response of the system to a console command.
If the system is operating with a single zone running, you must use a console
terminal (local or remote) that is connected to that zone for input commands.

3.3 Console Operating Modes
Operators communicate with the system in one of the following input/output
modes:
•

Program I/O (PIO) mode

•

Console I/O (CIO) mode

Normal operation takes place in the PIO mode. From PIO mode, the operator
uses the console to:
•

•

Use the mail facility

•

Create and edit files

From CIO mode, the operator executes the console commands. These commands
are described in Chapter 4.

3.4 Console Control Characters
The ASCII control characters and function keys listed in Table 3–3 have special
meanings when typed on a console terminal.
Table 3–3 Console Control Characters and Function Keys
Character/Key

Function

Break

In CIO mode, acts like Ctrl/C . In PIO mode, causes the processor to
halt and begin running the console program.
If the system is in a secure mode when you press the Break key,
the halt is suppressed. If you press the Zone Halt Enable or System
Halt Enable switch, the halt (initiated by pressing the Break key
earlier) is enabled.

Ctrl/C

Echoes ^C and causes the console to abort processing of a command,
if possible.

Ctrl/O

Alternately enables and disables output.

Ctrl/Q

Resumes output previously suspended by Ctrl/S .

Ctrl/R

Echoes ^R and retypes the command line.

Ctrl/S

Stops transmission until Ctrl/Q is typed.

Ctrl/U

Echoes ^U and ignores the current command line. The console
prompt is displayed on the next line. This affects only the entry of
the current line. Pressing Ctrl/U does not abort a command that is
executing.

<x (delete)

Deletes the character to the left of the cursor. On video terminals,
the deleted characters disappear. On hard-copy terminals, the
deleted characters are typed within a pair of backslash delimiters
as they are deleted.

Esc or Ctrl/[

Suppresses any special meaning associated with a given character.

Return

Terminates a command line and executes the command.

Console Operations 3–5

3.5 Console Command Language Syntax
The console commands accept qualifiers. Qualifiers specify a numerical value or
select an option from a list of options. Command elements may be abbreviated
and any extra tabs or spaces are ignored. Unless otherwise noted, numerical
values must be given in hexadecimal notation. The command length may not
exceed 80 characters.
Table 3–4 lists the console command language syntax rules. The console
commands available for the system are listed in Chapter 4.
Table 3–4 Console Command Language Syntax

Rule

Abbreviations

A command verb or argument may be abbreviated to the
extent that it remains unique.

Multiple adjacent spaces and
tabs

Are treated as a single space.

Qualifiers

May appear after a command verb, option, or symbol.
They must be preceded by a slash (/).

Numbers

Must be hexadecimal.

No characters

Are treated as a null command. No action is taken.

3–6 Console Operations

3.6 Bootstrap Procedures
The BOOT command initializes the system and then loads and starts the virtual
memory bootstrap (VMB) program from read-only memory (ROM). The VMB
program, in turn, loads and starts the operating system from the specified boot
device. Figure 3–3 shows the steps in the boot procedure.

MR−0490−92RAGS

The VMB program is the primary bootstrap program. VMB:
•

Resides in ROM on the ATM module.

•

Is loaded into memory and initiated by the system console firmware.

•

Provides the necessary parameters for successful operation of the VMS
secondary bootstraps.

•

Allows you to boot from DSSI compatible disk and tape devices over the
Ethernet.

CIO Mode Console Commands 4–1

4.2 Entering CIO Mode
To recognize and process CIO commands:
•

The System Halt Enable switch on both zone control panels must be pressed

•

The operating software must be halted

•

The processor must be running the console firmware

The example below shows how to use the Break key to enter CIO mode from PIO
mode and then return to PIO mode by using the CONTINUE command. (The
System Halt Enable switch on both zone control panels must be pressed.)
Caution
Use CONTINUE to continue from a system halt. Use START/ZONE to
continue from a zone halt.

A remote operator can use CIO mode only when full access privileges for the
remote console have been set at the local console.
Example
$
Press the System Halt Enable switch on both zone control panels.
$
$
! From PIO mode, press the Break key once.
$ Break
! This puts the processor in HALT mode.
>>>
!
?002 External halt
!
PC = 01E01473
!
>>> CONTINUE
$

! This command resumes execution of the
! operating system software.
! The console returns to PIO mode.

Notice that comments (characters following an exclamation point (!)) are allowed
on a command line. Comments are ignored by the console when the Return key is
pressed. This may be useful when you document a console session on a hardcopy
terminal.
Notice also that lowercase characters are accepted, but the console converts all
characters to uppercase.

4–2 CIO Mode Console Commands

4.3 CIO Mode Console Commands
This section describes the CIO mode console commands.

4.3.1 BOOT
BOOT initializes the system, loads a program image from a specified boot device,
and transfers control to that program image.
When you do not supply a boot-spec, the default boot device is used. When you do
not supply flag(s), a value of 0 is assumed.
The console program accepts a terminating colon on the boot-spec, but ignores the
colon when the name is processed.
The BOOT syntax is:
BOOT[/OVER][[/R5:]<flag(s)> boot-spec]
The boot-spec format may be dduuu/PATH=path-list . . . dduuu/PATH=path-list,
where:
dd is a device mnemonic.
uuu is a unit number (0 to 999).
/PATH=path-list is a qualifier. See Table 4–1.
Or, the boot-spec format may be a variable that specifies the boot devices and
paths. See Section 4.3.13.1.
Table 4–1 describes the qualifiers. Table 4–2 lists the VMB program /R5:<flag>
values.
Table 4–1 Qualifiers for BOOT
Qualifier

Function

/R5:<flag>

Passes parameters to the virtual memory bootstrap (VMB)
program. See Table 4–2.

/PATH=path-list

Specifies a path to a boot device. The path-list specifies zones
and slot numbers in the path. When the path-list has more
than one slot, you separate the slots by commas. The path-list
format is zss, where:
z is a zone ID (A or B).1
ss is a slot number (10 to 17, 20 to 27) of an adapter
connecting to a boot device.

/OVER

Overrides the results of the bootability test to allow a Simplex
mode boot.

1 The console validates this field before invoking VMB.

x0000000

Top-level system
boot

Specifies the top-level directory number for
a system disk with multiple system roots,
where x = a hex value from 0 to F.

4.3.2 CLEAR
CLEAR BOOT deletes a boot-spec. CLEAR ERRORS clears the error frame of the
previously detected error. If you do not clear the error frame, the next error is not
recorded in the error frame. CLEAR BROKE clears the broke bit in EEPROM.
The following CLEAR syntax deletes a boot-spec:
CLEAR BOOT <name>
The following CLEAR syntax clears the error frame:
CLEAR ERRORS
The following CLEAR syntax clears the broke bit ID in EEPROM:
CLEAR BROKE[/PATH=path-number]
Table 4–3 describes the /PATH=path-number qualifier.
Table 4–3 Qualifier for CLEAR
Qualifier

Function

/PATH=path-number

Specifies the zone and slot number of the module to clear. The
path-number format is zss, where:
z is the zone ID (A or B).
ss is the slot number (0 to 2, 10 to 17, 20 to 27) of an
adapter connecting to a DSSI device.

CLEAR BROKE clears the module ID EEPROM in the zone that is running.

4–4 CIO Mode Console Commands

4.3.3 CONTINUE
CONTINUE exits the CIO mode and returns operation to the PIO mode.
Caution
Use CONTINUE to continue from a system halt. Use START/ZONE to
continue from a zone halt.

The CONTINUE syntax is:
CONTINUE

4.3.4 DEPOSIT
DEPOSIT stores the specified data in the specified address.
When the system is initialized or when any transition from a running to a halted
state occurs, the defaults are physical address space 0 and data size longword.
The DEPOSIT syntax is:
DEPOSIT[/{B,W,L,Q}][/{G,I,M,P,V,U}][/N:count]address-spec data-spec
The address-spec identifies a physical or virtual hexadecimal memory address. A
qualifier may be placed before or after an address-spec or data-spec.
The data-spec identifies a hexadecimal number to be stored, unless the default
radix has been changed with a %D introducer. When you do not supply a
data-spec, a value of 0 is assumed.
Table 4–4 describes the qualifiers. Table 4–5 lists the address-spec symbolic
addresses.
Table 4–4 Qualifiers for DEPOSIT
Qualifier

Function
