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 utilities. You can use these tests and commands in privileged
console mode only if the console security feature is enabled and the password is set.

•

Configuration display

•

Error display

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.

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.

5–2 MicroVAX 3100 Models 88/98 User Information

Diagnostic Tests and Commands
•

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.

Diagnostic Tests and Commands

Operating system messages start here.

Abbreviated error message for memory error
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.

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.
By entering this command, you can see a list of diagnostic tests.
