Periodic Diagnostics Service Aid

This service aid provides a tool for configuring periodic diagnostics and automatic error log
analysis. A hardware resource can be chosen to be tested once a day, at a user specified
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 user(s) belonging to the system group with
information about the failure such as 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.

Product Topology Service Aid

This service aid provides enhanced product and order quality.

SCSI Bus Service Aid and SCSI Bus Analyzer Task

This service aid provides a means to diagnose a SCSI Bus problem in a free-lance mode.
Prior to version 4.2 the SCSI Bus Service Aid was accessed via the SCSI Bus selection from
the Service Aid Selection Menu. Beginning with version 4.2 the SCSI Bus Service Aid is
accessed via the SCSI Bus Analyzer option from the Task Selection Menu.
To use this service aid, the user should have an understanding of how a SCSI Bus works.
This service aid should be used when the diagnostics cannot communicate with anything on
the SCSI Bus and cannot isolate the problem. Normally the procedure for finding a problem
on the SCSI Bus with this service aid is to start with a single device attached, ensure that it
is working, then start adding additional devices and cables to the bus ensuring that each one
works. This service aid works with any valid SCSI Bus configuration.
The SCSI Bus Service Aid transmits a SCSI Inquiry command to a selectable SCSI
Address. The service aid then waits for a response. If no response is received within a
defined amount of time, the service aid displays a timeout message. If an error occurs or a
response is received, the service aid then displays one of the following messages:
The service aid transmitted a SCSI Inquiry Command and received a valid response back
without any errors being detected.
The service aid transmitted a SCSI Inquiry Command and did not receive any response
or error status back.
The service aid transmitted a SCSI Inquiry Command and the adapter indicated a SCSI
bus error.
The service aid transmitted a SCSI Inquiry Command and an adapter error occurred.
The service aid transmitted a SCSI Inquiry Command and a check condition occur.
