Chapter 17. SSA Service Aids
Note: For some problems, you can use the SSAcommand line utilities instead of the
SSAservice aids. For information about the command line utilities, see
Chapter16, “Using the SSACommand Line Utilities”on page341.
SSAservice 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: Do not run the service aids from more than one using system at a time;
otherwise, unexpected results might occur.
The SSAservice aids are:
vSet Service Mode: This service aid enables you to determine the location of a
particular disk drive on the SSAloop, and to remove that disk drive from the loop.
vLink Verification:This service aid tells you the operational status of the links that
make an SSAloop.
vConfiguration Verification:This service aid lets you determine the relationship
between physical and logical disk drives.
vFormat Disk: This service aid formats an SSA disk drive.
vCertify Disk: This service aid verifies that all the data on a disk drive can be read
correctly.
vDisplay/Download Disk Drive Microcode: This service aid allows you to observe
and modify the microcode level on all the SSAdisk drives.
vLink Speed: This service aid allows you to observe the operating speed of each link
on an SSAloop.
vPhysical Link Configuration: This service aid provides support for SES-enabled
SSAenclosures (subsystems). See your enclosure service information for a
description of this service aid.
vEnclosure Configuration: This service aid provides support for SES-enabled SSA
enclosures (subsystems). See your enclosure service information for a description of
this service aid.
vEnclosure Environment: This service aid provides support for SES-enabled SSA
enclosures (subsystems). See your enclosure service information for a description of
this service aid.
vEnclosure 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 SSAservice aids allows you direct access to the SMIT
menus for fast-write and RAID functions on SSAdisks.
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 Chapter2, “Introducing SSALoops”on page7.
