Run Diagnostics
The Run Diagnostics task invokes the Resource Selection List menu. When the commit
key is pressed, diagnostics are run on all selected resources.
The procedures for running the diagnostics depends on the state of the diagnostics
run-time options. See “Display or Change Diagnostic Run-Time Options” on page110.
Run Error Log Analysis
The Run Error Log Analysis task invokes the Resource Selection List menu. When the
commit key is pressed, Error Log Analysis is run on all selected resources.
Run Exercisers
The Run Exercisers task provides a tool to troubleshoot intermittent system problems in
AIX 4.3.2 or later, to test hardware, and to verify replacement parts. When AIX error
logging is enabled, the Run Error Log Analysis task can be used to analyze errors after
the exerciser completes. Hardware errors are logged in the AIX Error Log. Miscompares
and recoverable errors are not reported, however, they may be logged in the AIX Error
Log when logging thresholds are exceeded.
The diagnostic supervisor typically sets up temporary work files in /tmp to log
messages and device statistics. These files are deleted before an exerciser session
begins. In addition to individual exerciser requirements, the following requirements
pertain to all exercisers:
vOnly supported on CHRP platforms
vOnly supported in concurrent or service modes
vNot supported from standalone diagnostics
vSystem performance will be degraded while running the exerciser, so it is
recommended that customer applications be shut down before it is run.
vAt least 1 MB of free storage in /tmp is available
From the TASK SELECTION LIST menu selectRun Exercisers then the RESOURCES
SELECTION LIST menu displays. From this menu choose the resources you want to
exercise and then select commit to start the Run Exerciser task. An intermediate
popup may appear stating system performance will be degraded. (The popup does not
appear if the task had previously been selected). Press Enter and the EXERCISER
OPTIONS menu prompts for the type of test to run.
The EXERCISER OPTIONS menu displays two options (1) Short Exercise and (2)
Extended Exercise. The Short Exercise option exercises the resources within a
relatively short time and exits. The Extended Exercise option allows greater flexibility
and control over resources and test duration.
After choosing the Short Exercise option, additional menus, pop-ups and prompts may
appear for each resource. Please read any text and carefully fill out any prompts before
committing. Next, the exercisers start, and the Device Status Screen displays. The
exercisers runs 5 to 10 minutes depending on the number of processors, processor
