Preface
Troubleshooting is the process of isolating and diagnosing problems with
your system. When your system does not operate as described in Operation,
use the information in this guide to diagnose the problem.
This book contains troubleshooting information for all MicroVAXlVAXserver
systems: MicroVAX II and MicroVAX 3000-series systems. Appendix A
contains diagrams of each MicroVAX system. Using the diagram of your
system, follow the troubleshooting procedures recommended in this guide.
This manual contains three chapters:
•

Chapter 1 describes problems you may experience at power-on and
corrective actions.

•

Chapter 2 describes problems you may have during normal operation
of your system and corrective actions.

•

Chapter 3 describes the MicroVAX Diagnostic Monitor (MDM), a
diagnostic tool you can use to test your system periodically or to isolate
a particular problem.

•

Appendix A contains diagrams of each system showing the location of
the controls and indicators.

The troubleshooting techniques described in this manual do not identify all
possible problems with your system, nor do the actions suggested remedy
all problems. If the actions suggested do not solve the problem, call your
DIGITAL service representative.

Chapter 1

Troubleshooting During Power-On
When you power on your system, the MicroVAX processor performs a series
of self-tests and start-up routines. After successful completion of the selftests, if the Break EnabieIDisable1 switch is set to disable, the system
attempts to autoboot system software.

1.1 Autobooting the MicroVAX System
The MicroVAX autoboot function is different for each MicroVAX system.

1.1.1 Autobooting MicroVAX 3300/3400/3800/3900 Systems,
and MicroVAX 3500/3600 Systems with Version 4.1
ROM Code (or greater)
The MicroVAX 3300,3400,3800,3900 systems, as well as those MicroVAX
3500 and 3600 systems using version 4.1 ROM code or greater, attempt to
automatically boot (autoboot) from a specified drive when you have used
the Set Boot command (SET BOOT device name) from console mode. The
system continues to boot from the specified device each time it is powered
on until you specify differently by using the Set Boot command again.
If you have not used the Set Boot command, the system boots automatically
from the Ethernet port, ESAO.

1.1.2 Autobooting MicroVAX 3500 and 3600 Systems
The MicroVAX 3500 and 3600 systems using version 1.2 or 1.4 ROM code,
attempt to autoboot a specific drive when you use the Set Boot command
(SET BOOT device name) from console mode. The system continues to
boot from the specified device each time it is powered on until you specify
differently by using the Set Boot command again.
If you have not used the Set Boot command, the system attempts to
autoboot by looking for bootable software the same way a MicroVAX II
system looks for bootable software. See Section 1.1.3 for more information.
1 MicroVAX II systems have a Halt EnablelDisable switch.

Troubleshooting During Power-On 1-1

1.1.3 Autobooting MicroVAX II Systems
When a MicroVAX II system attempts to autoboot, it looks for bootable
software on the following devices in the order shown below:
1. Removable disks and diskettes (RX33, RX50, and RA60 in ascending
unit number)
2. Fixed-disk drives (RD-serieslRA-seriesIRF-series in ascending unit
number)
3. Tape cartridges (TK50trK70, TS05, TU81-Plus)
4. EPROM
5. Ethernet adapter
Normally, the system automatically boots system software which has been
installed on a fixed-disk drive. When booting a fixed-disk drive, you must
remove all removable disks and place all disks ahead of the disk containing
the system software off-line. For example, if you want to boot system
software from an RA81 or RA82 fixed disk, place all removable media, as
well as all RD-series and RF-series disks, and RA60 disks (if any) off-line.
(See operating instructions for each drive in your system-specific Operation
manual.)

To boot software from a TK50 or TK70 tape cartridge, or the Ethernet, you
must place all removable and fixed-disk drives off-line.
An alternative to placing disks off-line is to boot your system manually
from the console terminal using the BOOT device name command in console
mode. (See Operation for more information.)

1.2 Troubleshooting Power-On Problems
If you do not observe the correct power-on and boot sequence responses,
refer to the possible problems and corrective actions described in Table 1-I.
If the actions listed do not solve the problem, call your DIGITAL service
representative.

NOTE: Table 1-1 occasionally recommends that you run MDM as a service
tool to help diagnose problems. Refer to Chapter 3 of this manual for
instructions on using MDM.

Chapter 3

Running the MicroVAX Diagnostic
Monitor (MOM)
The MicroVAX Diagnostic Monitor (MDM) is a software package containing
diagnostic tests designed to isolate and identifY faults in your MicroVAX
system. MDM also permits you to display your system configuration,
reformat disks, and, if your system has two or more megabytes of memory,
test how devices work together. The diagnostic tests are packaged with your
system on either RX50 diskettes (labeled MV DIAG CUST RX50) or a tape
cartridge (labeled MV DIAG CUST TK50). MDM operating instructions
begin in Section 3.2.
CAUTION: If your system is connected to a cluster, notify your cluster
manager before halting the system to load MDM.

You generally run MDM in three situations:
•

Before you install system software on a new system

•

When you receive an error message or experience a problem with your
system

•

When you want to test your system periodically to ensure that all
components are operating correctly

How the MOM Tests Work

MDM tests individual devices in your system. However, MDM performs
limited diagnostics:
•

It performs reads from each drive and checks each controller. The
customer tests do not write to the drives as writing to the drives could
destroy data.
NOTE: MDM will test a tape drive or diskette drive only when the media
(tape or diskette) is inserted in the drive.

•

It checks only devices themselves and not the connections or lines
between peripheral devices and the system.

Running the MicroVAX Diagnostic Monitor (MOM)

3-1

•

It does not check each device as thoroughly as the service diagnostic
tests, which are described below.

If devices pass the customer tests but you still experience problems, contact
a DIGITAL service representative for further testing.
Customers requiring more complete diagnostic testing should purchase the
MicroVAX Maintenance Kit. The maintenance kit includes the system
maintenance guide and the service diagnostic tests. The MDM version
that you receive with your system is a subset of the service version.
NOTE: Only qualified service personnel should use the service diagnostic

tests.

3.1 Running MOM Under Special Circumstances
Running MDM for certain systems requires additional or special
procedures. Read the appropriate section if you plan to run MDM on a
diskless and tapeless system, a VAXserver 3602 system, a dual-host system,
or if you plan to install MDM on a hard disk or RF-series Integrated Storage
Element (lSE).

3.1.1 Running MDM on Diskless and Tapeless Systems
If you have a diskless and tapeless system that is part of a local area

network (LAN), you must obtain the MicroVAX Ethernet Server Customer
Diagnostics Kit. Run MDM using the diagnostics in the kit that is labeled
MV DIAG ENET CUST.
Refer to the MicroVAX Diagnostic Monitor Ethernet Server User's Guide at
this time. Once you have installed and down-line loaded MDM software,
refer again to this manual for specific instructions on running MDM.
NOTE:

1. If you have a diskless and tapeless system that is not part of a local
area network (LAN), you cannot run MDM. To diagnose problems, call
a DIGITAL service representative.

2. If your system is part of a local area network (LAN), you may want to
reduce the time required to load MDM on each system by obtaining the
Micro VAX Ethernet Server Customer Diagnostics Kit. The kit enables
you to install MDM software on a host VMS operating system and downline load MDM to other systems that are part of the LAN, using the
DECnet / Ethernet network facilities. When MDM is down-line loaded

3-2 MicroVAX Troubleshooting and Diagnostics

to target systems from a host system, the time required to load MDM is
reduced significantly.

3.1.2 Running MDM on a VAXserver 3602 System
If you have a VAXserver 3602 system, the CPU in the secondary cabinet
cannot boot diagnostic software from a tape cartridge. You must down-line
load the diagnostic software from the primary cabinet.

The MicroVAX Ethernet Server Customer Diagnostics Kit contains the
MDM diagnostic software and a MicroVAX Diagnostic Monitor Ethernet
Server User's Guide. The user's guide describes how to install MDM
software on a host VMS or MicroVMS operating system and how to downline load MDM to a diskless target system, using the DECnet/Ethernet
network facilities.

3.1.3 Installing MDM on RF-series ISE or Hard Disk
MDM software can be installed on an RF-series ISE or an RA-, RDseries hard-disk drive using the MDM Hard Disk Kit. Installation of
the MDM Hard Disk Kit requires the completion of the "Diagnostic
Software Installation Acknowledgment" by the customer. See the Micro VAX
Diagnostic Monitor Hard Disk User's Guide for the licensing requirements
and installation instructions.
NOTE: The MDM Hard Disk Kit is required for dual-host systems where
one host is a tapeless system.

3.1.4 Running MDM on a Dual-Host System
In a dual-host configuration, two MicroVAX systems in the same VAXcluster
share their ISEs through a Digital Storage System Interconnect (DSSI) bus.
Each system can directly access any of the ISEs in either system; this can
include a shared common system disk.
Before running MDM diagnostics on a dual-host system, your system must
be properly configured (systems ordered as dual-host systems are properly
configured at the factory) and the DSSI cable connecting the two hosts must
be in place.
Diagnostics must be performed separately for each host. The procedure for
running diagnostics differs depending on whether one host is a tapeless
system (no tape drive) or each host has its own tape drive. Use the
instructions in Section 3.1.4.1 to run diagnostics in a dual-host system with
one tape drive. Use the instructions in Section 3.1.4.2 to run diagnostics in
dual-host systems with a tape drive in each host.

Running the MicroVAX Diagnostic Monitor (MDM)

3-3

3.1.4.1 Running MDM on a Dual-Host System with One Tape Drive

Dual-host systems with one tape drive (one tapeless host) require the
MDM Hard Disk Kit. Complete the "Diagnostic Software Installation
Acknowledgment" and install the kit on an RF-series ISE according to the
procedure in the Micro VAX Diagnostic Monitor Hard Disk User's Guide.
NOTE: Micro VAX II systems have a Restart button on the front panel, rather
than a Reset button; and a Halt Enable / Disable switch, rather than a Break
Enable / Disable switch. The text refers to the switches as the Reset switch
and the Break Enable / Disable switch.

When the installation is complete, use the following procedure to run the
diagnostics:
1. Set the Break EnablelDisable switch on both hosts' CPU panels to
enable (up, dot inside the circle). Turn on both hosts. If the hosts
are already powered-up, press IBREAKI.

Result: You should see the »> prompt indicating console mode on your
terminal.
2. Use the command BOOT/100 DIAn (for KA640 CPU based DSSI) or
BOOT/100DUAn (for KFQSA based DSSI), where n is the unit number
of the disk containing the MDM Hard Disk Kit.

Result: The system prompts for the boot:file:
Bootfile:

Enter the name of the :file image: [SYSO.SYSEXE]MDMDIA.SYS for
systems with on-board DSSI, or [SYSO.SYSEXE]MDM.SYS for systems
using the KFQSA storage adapter. Press IRETURN I to continue booting.
3. Run the diagnostics as described in this chapter.
4. When you have completed the tests on the first host, make sure the
Break EnablelDisable switch is set to enable (up, dot inside the circle)
and press the Reset button on that same host. When the countdown
completes and the »> prompt appears, boot the diagnostics from the
second host using the commands described in steps 2 and 3, and run
the diagnostics as you did for the first host.

3-4 MicroVAX Troubleshooting and Diagnostics

3.1.4.2 Running MDM on a Dual-Host System with Two Tape Drives

Run diagnostics on dual-host systems with two tape drives according to the
following procedure:
NOTE: You can also use the MDM Hard Disk Kit as described in the
previous section.

1. If software is installed on the system, warn all users to log off
and perform system shutdown, as described in your system software
manuals. Turn off both hosts.

2. Make sure the Write-Protect switch on the tape cartridge containing
the MDM diagnostics is in the write-protect position.
3. Set the Break EnablelDisable switch on both hosts' CPU panels to
enable (up, dot inside the circle).
4. Turn on both hosts.
Result: The normal power-on countdown should appear on the console
terminal. After the countdown, you should see the »> prompt
indicating console mode.
5. Insert the tape cartridge containing the MDM software into the tape
drive in one host system and lock it into place. For the same host,
use the command BOOT MUAO to tell your system to load the MDM
software from the tape cartridge.
6. Run the diagnostics as described in this chapter.
7. When you have completed the tests on the first host, remove the tape
cartridge by following the procedure described in your system-specific
Operation manual. Press the Reset button on that same host. When
the countdown completes and the »> prompt appears, insert the tape
cartridge into the tape drive in the second host and lock it into place.
Use the command BOOT MUAO to boot the tape and run the diagnostics
as you did for the first host.

3.2 Starting MOM
CAUTION:
Before you run the MDM software:

•

Be sure you understand the instructions in your system-specific
Operation manual (contained in this documentation kit) for using the
device appropriate for your diagnostic media - either the RX50 diskette
drive or the TK50/ TK70 tape drive.
Running the MicroVAX Diagnostic Monitor (MDM)

3-5

•

Make sure the media (tape cartridge or RX50 diskette) is write-protected.

You must start the diagnostic tests differently for different media. If you
are booting MDM from an RX50 diskette, read Section 3.2.1. If you are
booting MDM from a tape cartridge, read Section 3.2.2. If you are booting
MDM from an RF-series ISE or an RA-, RD-series fixed-disk drive, refer to
the MicroVAX Diagnostic Monitor Hard Disk User's Guide.
NOTE: Unless instructed to do so, do not change any settings or manipulate
devices while the tests are running. The diagnostic software interprets any
change of state as an error.
NOTE: If you are using an RX33 diskette drive, follow the instructions for
running MDM from RX50 diskettes.

3.2.1 RX50 Diskette Instructions
Because the system automatically boots first from an RX50 diskette, you
can run MDM software whether or not the system software has been
installed on the system.
CAUTION: Before booting MDM on a system with software installed, warn
all users to log off and perform system shutdown, as described in your system
software manuals.

To run diagnostic software from RX50 diskettes, do the following:
1. Make sure the Halt EnablelDisable switch is set to disable (down).
2. Set the fixed-disk 0 Ready button on the system control panel to the
out position.
3. Insert diskette RX50A into one of the drives (be careful to align the
orange arrow on the diskette with the orange stripe on the drive) and
close the door.
4. Press the Restart button if the system is running, or tum on the system
if the system is off.

Result: A countdown from 7 to 3 should appear on the console terminal
as the system performs self-tests. The countdown continues from 2 to
o as the system loads the diagnostic software.
5. At this point, you may be prompted to remove diskette RX50A and
insert the next boot diskette. Remove diskette RX50A and insert
diskette RX50B.

(

Result: Within a few moments you should see the MDM introductory
display.

6. Make sure the current date and time in the introductory display are
correct. If the date and time are correct, press IReturn I to continue. If
incorrect, type the correct date and time, using the format shown in
the MDM introductory display screen. For example, enter 25-DEC198802:30 and press IReturn I to continue.
Result: Within moments the Main Menu appears. Section 3.3 describes
options on the Main Menu.

7. When you select a menu option, you may be asked to insert additional
diskettes. Insert the specified diskettes when prompted by the system.
If your system does not request all the diskettes containing diagnostic
software, your configuration does not need the additional diskettes for
testing.
Result: After a few minutes, you receive a message that the various
diagnostics are configuring and that the system is ready for testing.

When you press IReturn I, the selected option will continue.

3.2.2 TK50ITK70 Instructions
The diagnostics run the same way whether or not system software, such as
VMS, ULTRIX-32, or VAXELN, has been loaded. You can manually boot
the diagnostic software or use the autoboot feature to automatically boot
the software. The following sections explain how to boot MDM manually
and automatically, as well as how to boot MDM on VAXserver 3602 systems.
Carefully follow the directions for setting switches.
NOTE: Before running MDM on your TK50 or TK70 tape drive, you may
want to reread the tape drive operating instructions found in your systemspecific Operation manual.
3.2.2.1 Booting MOM Manually
NOTE: Before booting MDM on a system with software installed, warn all
users to log off and perform system shutdown, as described in your system
software manuals.

service diagnostics and the system maintenance guide. Only qualified
service personnel should use the MicroVAX Maintenance Kit.
The next five sections describe the remaining options on the Main Menu.

3.3.1 Test the System
The "Test the System" option runs a quick, general test of the devices in
the system and how they work together. You can run the test at any time
without jeopardizing data.
When you select "Test the System," the diagnostics are prepared for testing.
If this is the first MDM option you have selected, the diagnostics are
automatically loaded. The loading process takes several minutes. When
the preparations and loading are complete, you are prompted to press IReturn L
A screen explaining the testing procedures then appears.
When you are ready to begin the test, press 1Return I. The "Begin Device Tests"
screen appears.

3-10 MicroVAX Troubleshooting and Diagnostics

As each device passes the test, it is listed on the screen.
NOTE: Because of the internal similarity of some communications options,
the diagnostic test sees these options as the same device. A DHVll and
DHQll appear the same to the diagnostic test. A generic device name,
DH-CXO, is listed for similar communications options. The last letter in
each device name differentiates among multiple devices of the same type.
For example, DH-CXOA indicates one communications option, DH-CXOB a
second, and so forth.

If a device fails the test, you receive a failure message.
Each failure message identifies the device being tested, when the failure
occurred, and the field replaceable unit (FRU). Copy the failure message
and report it to your DIGITAL service representative. Figure 3-2 shows
an example of an unsuccessful test.

In addition to showing information about testable device options, MDM
displays messages indicating the presence of nontestable system devices.
If a device is physically present in the system but is not described under
the "System Configuration and Devices" display, one of the following two
messages can indicate the reason.
Message 1:
No Dg KAA ... Diagnostic not loaded

The "No Dg" (no diagnostic) "KAA" (KA630 CPUA) message appears in place
gfthe device name because a diagnostic was not loaded for the CPUA This
can happen when the media is not installed properly or the diagnostic is
not present on the media.
MDM displays a "No Dg" message for each DIGITAL device present in
the system under these circumstances. For example, if MDM cannot find
the TK70 tape drive diagnostic, the message "No Dg TKA" appears. TKA
indicates that the device is a TK tape drive.
