If you have AIX® installed and it can be started, use this procedure
to perform diagnostic procedures when directed from another procedure or by
your next level of support.
When you run online diagnostics, keep the following in mind:
- When AIX is installed,
the support for some devices might not be automatically installed. If this
happens, that device will not display in the test list when online diagnostics
run.
- When running diagnostics in a logically partitioned system, you must run
diagnostics in the logical partition containing the resource or resources
that you want to test.
Three modes are available for running the online diagnostics:
- Service mode provides the most complete check of
the system resources, but requires that no other programs are running on the
system. When possible, run the diagnostics in service mode.
- Maintenance mode allows you to check most of the
available resources, with the exception of SCSI adapters, memory, processor,
and the disk drive used for paging.
- Concurrent mode allows you to run online diagnostics
on some of the system resources while the system is running normal activity.
