SSA Service Aids
SSA service aids help you service the SP. This section describes those service
aids, and tells how to use them.
Attention: Do not run the service aids from more than one system at a time; other-
wise, unexpected results might occur.
The SSA service aids are:
Set Service Mode This service aid enables you to determine the
location of a particular disk drive module on the
SSA link and to remove that module from the link.
Link Verification This service aid tells you the operational status of
an SSA link.
Configuration Verification This service aid lets you determine the relationship
between physical and logical disk drives.
Format Disk This service aid formats an SSA disk drive module.
Certify Disk This service aid verifies that all the data on a disk
drive can be read correctly.
Before you use the service aids, ensure that you are familiar with the principles of
SSA links and physical disk drives (pdisks). If you are not familiar with these princi-
ples, first read “SSA Loops and Links” on page 7-25.
