Disk Service Aids
The Service Aids allow you to perform general maintenance functions on a selected
physical disk drive. They are accessible through the configurator utilities when an
adapter is selected. The service aids available are:
Service Mode: (Set and Reset) Service Mode enables you to find a selected disk
drive on the SSA loop, and to remove the drive from the loop.
Format Disk: This formats an SSA disk drive.
Certify Disk: This verifies that all the data on a disk drive can be read correctly.
Diagnostics: Concurrent and Nonconcurrent diagnostics are available.
Attention: Do not run the service aids from more than one system at a time, otherwise
unexpected results might occur.
Before using the service aids, ensure that you are familiar with the principles of SSA
loops. If you are not, first read the introductory information given in the
