Re: SSA_ARRAY_ERROR



Sorry for the delay.

Your error is as foolows:

SRN 47500:

47500
Description: Part of the array data MAY NOT be available. This SRN is
surfaced during RAID-5 Array Rebuild after a DDM has failed. During
replacement of the DDM or use of a Hot Spare, a unrecoverable media error is
detected on another DDM. This results in a double fault condition. A Bad
strip is marked. The array rebuild will complete with a bad strip indicated
like the following example.
"List Status of All Defined SSA RAID Arrays" in "smitty" :

Unsynced Parity Strips Unbuilt Data
Strips

hdisk2 0 0

hdisk3 0 0

hdisk4 0 0

hdisk5 0 0
Invalid data strip



Action:
If you have SSA adapter types 4-M or 4-N, Ensure Microcode 7301 or
higher is installed, or if you have SSA adapter type 4-P, Ensure Microcode
8300 or higher is installed. These microcodes enhance error recover & Disk
Drive Data Scrubbing techniques.

Check also if you have SRN1XXXX (X if a Hex digit 0 - F), SRN49000,
SRN31000 or SRN50422.

In particular if this SRN47500 happened AFTER a DDM was replaced for a
1XXXX error, and the SRN1XXX was preceeded with a SRN50422.

Go to (Array Product Service Guide Map 2324).

Execution of this map is MANDATORY for SRN47500. Recovery may be 100%
successful if the Media error was in Free/Unused Customer data space on the
Array.

If the Media error is in used space then the data will need to be
recovered from backup sources as per this map.



Oops! good luck with this one.

Eric.

Hello Eric,

thanks for answering so quickly. We didn´t define hotspare disks for
our SSA-Arays. So it couldn´t be a possibility for this fault. Do you
have any other idea?
