MAP 2324: SSA RAID

This MAP helps you to solve problems that have occurred in SSA RAID arrays.

Attention:

Unless the using system needs to be switched off for some other reason,

do not switch off the using system when servicing an SSA link or an enclosure in which
SSA devices are installed
. Enclosure power cables and external SSA cables that
connect devices to the using system can be disconnected while that system is running.

Before starting this MAP, ensure that all the disk drives are working correctly:

1. Run diagnostics in Problem Determination mode to identify any disk drive problems

that have occurred.

2. Run the Link Verification service aid (see “Link Verification Service Aid” on

page 383) to find all power problems, SSA link problems, and SSA disk drives that
have a Failed status.

3. Correct all those problems before you start this procedure.

Attention:

Some of the steps in this MAP need you to change the configuration of the

array, or to change the use of an SSA disk drive. Do not do those steps unless you
have the user’s permission.

1. (from steps 3, 28, and 29)

You have been sent to this step either from another step in this MAP, or because
you have one of the following Service Request Numbers (SRNs):

46000, 47000, 47500, 49000, 49100, 49500, 49950

Do you have SRN 49500?

NO

a. Run diagnostics in System Verification mode to the SSA adapters.

b. Go to step 2.

YES

No hot spare disk drives are available.

Go to step 21 on page 466.

2. (from step 1)

Did the diagnostics produce SRN 46000, 47000, 47500, 49000, 49100, or
49950?

NO

Go to step 3 on page 455.

YES

Go to step 4 on page 455.
