Periodic Diagnostics Service Aid
This service aid provides a tool for configuring periodic diagnostics and automatic
error log analysis. A hardware resource can be tested once a day, at a user speci-
fied time. If the resource cannot be tested because it is busy, error log analysis is
performed. Hardware errors logged against a resource can also be monitored by
enabling automatic error log analysis. This allows error log analysis to be performed
every time a hardware error is put into the error log. If a problem is detected, a
message is posted to the system console and a mail message sent to the users
belonging to the system group with information about the failure such as the service
request number.
The service aid provides the following functions:
Add or delete a resource to the periodic test list
Modify the time to test a resource
Display the periodic test list
Modify the error notification mailing list
Disable automatic error log analysis
