Preface
Troubleshooting is the process of isolating and diagnosing problems. When
your system does not operate as described in your Operation manual, use
the information in this manual to isolate and diagnose the problem.
This manual contains three chapters and one appendix:
•

Chapter 1 lists problems you may experience at power-up and provides
corrective actions.

•

Chapter 2 lists problems you may experience during normal operation
and provides corrective actions.

•

Chapter 3 tells you how to run 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 illustrations showing the location of your system
controls and indicators.

If the corrective actions suggested in Chapters 1 and 2 do not solve the
problem, call your Digital service representative.
A glossary in your Operation manual will help you with word definitions
and abbreviations.

Conventions
The following conventions are used in this manual.
Convention

Meaning

Key

A terminal key used in text and examples. For example, Break indicates
that you press the Break key on your terminal keyboard.

Ctrl/C

Hold down the Ctrl key while you press the C key.

NOTE

Provides general information about the current topic.

CAUTION

Provides information to prevent damage to equipment or software.

Chapter 1

Troubleshooting During Power-Up
After you turn on your system, the processor performs a series of self-tests
and startup routines. After successful completion of the self-tests, if the
Break Enable/Disable switch is set to disable (down), your system autoboots
system software.

1.1 Autobooting the System Software
Your system boots automatically (autoboots) from a specified drive after
you enter the command SET BOOT device-name from console mode. Your
system continues to boot from the specified drive each time it is turned
on, until you specify differently by entering the SET BOOT device-name
command again.
If you do not enter the SET BOOT device-name command, your system
boots from the Ethernet port, EZA0.

1.2 Troubleshooting Power-Up Problems
Refer to the descriptions of problems and corrective actions in the following
sections. If the action(s) listed do not solve the problem, call your Digital
service representative.

Chapter 3

Running the MicroVAX Diagnostic
Monitor (MDM)
The MicroVAX Diagnostic Monitor (MDM) is an optional software package
containing diagnostic tests that isolate and identify faults in your system.
MDM also lets you display your system configuration and test how devices
work together.
MDM is on tape, in a 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 four situations:
•

Before you install software on a new system

•

After you add a device to your system

•

After you receive an error message or experience a system problem

•

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

3.1 MDM Limitations
MDM tests internal devices in your system, but it performs limited
diagnostics.
•

MDM reads from each drive and checks each controller, but it does not
write to the drives because that could destroy data.
NOTE: MDM tests a tape or diskette drive only after the medium (tape
or diskette) is inserted into the drive.

•

MDM checks devices on the system as well as the system and
interconnects.

Running the MicroVAX Diagnostic Monitor (MDM)

3–1

•

MDM checks terminal interfaces (but not terminals) by means of
feedback connectors.

If your devices pass the tests but you still experience problems, call your
Digital service representative for further testing.
If you require more complete diagnostic testing, purchase the MicroVAX
Maintenance Kit. That kit includes a system maintenance guide and the
service diagnostic tests. The MDM version you receive with your system is
a subset of the service version.
CAUTION: Only qualified service personnel should use the service
diagnostic tests.

3.2 Preparing to Run MDM
Running MDM on some systems requires additional or special procedures:
Read Section 3.2.1 if you plan to run MDM on a diskless or tapeless
system.
Read Section 3.2.2 if you plan to install MDM on a hard disk or RFseries Integrated Storage Element.
Read Section 3.2.3 if you plan to run MDM on a dual-host system.
You can run MDM on an RRD-series disc drive by using the MDM CDROM
Kit.

3.2.1 Preparing to Run MDM on a Diskless or Tapeless
System
To run MDM on a diskless or tapeless system that is part of a local area
network, you must:
•

Obtain a MicroVAX Ethernet Server Customer Diagnostics Kit.

•

Run MDM using the diagnostics in that kit, labeled MV DIAG ENET
CUST.

Refer to the MicroVAX Diagnostic Monitor Ethernet Server User’s Guide at
this time. After you install and downline load MDM, refer again to that
manual for instructions on running MDM.
NOTE: If you have a diskless or tapeless system that is not part of a local
area network, you cannot run MDM. To diagnose problems, call your Digital
service representative.
