1–8 Troubleshooting and Diagnosing Problems

1.3 Diagnostic Tests and Commands
There are a number of diagnostic tests and commands that can help you to
isolate a problem with the system unit. These tests and commands are as
follows:
•

Power-up tests

•

Diagnostic tests and utilities1

•

Configuration display1

•

Error display1

The following sections describe these tests and commands.

You can use these tests and commands in privileged console mode only if the console
security feature is enabled and the password is set. See the MicroVAX 3100 Model 90
Customer Technical Information manual for information on the console security
feature.

Troubleshooting and Diagnosing Problems 1–9

1.3.1 Power-Up Tests
The system runs the power-up tests each time you turn on the system. After
successful completion of tests, the system will either enter Console mode or
proceed to automatic bootstrap, depending on the HALT action selected by
the user. If HALT action is Default, Halt, or Restart, then the system enters
console mode. If HALT action is Reboot or Restart_reboot, then the system
proceeds to boot. The following example shows a typical display for a system
that passes all tests and then enters console mode.

1–10 Troubleshooting and Diagnosing Problems

Note
The operating system messages start here, i.e. VMS ..........

If the power-up tests encounter an error, one of the following actions occurs:
For minor errors:
•

If HALT action is set to a boot condition (that is reboot or
restart_reboot), and if a minor error occurs, the system displays an
abbreviated error message and continues to boot as normal.

•

If HALT action is set to Default, Halt or Restart, then the system
enters console mode.

•

The only errors defined as minor are errors in memory that cause pages
to be marked bad in the memory bitmap. There must be enough good
memory left to allow an attempt to bootstrap.

For severe errors:
•

The system always enters console mode regardless of HALT action after
it attempts to complete all tests possible.

The following example shows a system with a memory error that only affected
one set of memory out of two sets. Because some memory is still usable, the
system proceeds to automatic bootstrap if the HALT action is set to a boot
condition.

Memory errors normally cause the results of a SHOW MEMORY display to
occur after the tests are completed and before continuing. SHOW MEMORY is
the most useful command to determine which memory SIMMs are bad when
memory errors occur.

1–12 Troubleshooting and Diagnosing Problems

1.3.2 Diagnostic Tests and Utilities
The diagnostic tests and utilities are similar to the power-up tests except that
the power-up tests enable you to test all the devices in the system, whereas the
diagnostic tests and utilities enable you to test single devices and the functions
of single devices.
Figure 1–2 shows a list of diagnostic tests obtained by entering the following
command:
