Chapter 17. SSA Service Aids
Note: For some problems, you can use the SSA command line utilities instead of the
SSA service aids are resident in the using system. They help you to service SSA
subsystems. This section describes those service aids, and tells how to use them.
Attention:
otherwise, unexpected results might occur.
The SSA service aids are:
v Set Service Mode: This service aid enables you to determine the location of a
particular disk drive on the SSA loop, and to remove that disk drive from the loop.
v Link Verification: This service aid tells you the operational status of the links that
make an SSA loop.
v Configuration Verification: This service aid lets you determine the relationship
between physical and logical disk drives.
v Format Disk: This service aid formats an SSA disk drive.
v Certify Disk: This service aid verifies that all the data on a disk drive can be read
correctly.
v Display/Download Disk Drive Microcode: This service aid allows you to observe
and modify the microcode level on all the SSA disk drives.
v Link Speed: This service aid allows you to observe the operating speed of each link
on an SSA loop.
v Physical Link Configuration: This service aid provides support for SES-enabled
SSA enclosures (subsystems). See your enclosure service information for a
description of this service aid.
v Enclosure Configuration: This service aid provides support for SES-enabled SSA
enclosures (subsystems). See your enclosure service information for a description of
this service aid.
v Enclosure Environment: This service aid provides support for SES-enabled SSA
enclosures (subsystems). See your enclosure service information for a description of
this service aid.
v Enclosure Settings: This service aid provides support for SES-enabled SSA
enclosures (subsystems). See your enclosure service information for a description of
this service aid.
The selection menu for the SSA service aids allows you direct access to the SMIT
menus for fast-write and RAID functions on SSA disks.
Before you use the service aids, ensure that you are familiar with the principles of SSA
loops and physical disk drives (pdisks). If you are not familiar with these principles, first
read Chapter 2, "Introducing SSA Loops" on page 7.
SSA service aids. For information about the command line utilities, see
Chapter 16, "Using the SSA Command Line Utilities" on page 341.
Do not run the service aids from more than one using system at a time;
