Maintenance procedures include microcode updates,
failure recovery procedures, and working with the battery pack.
Follow the recommended maintenance procedures in this section to
help maintain your RAID controller for Linux®.
Usage tips
Follow recommended usage tips to help avoid controller
and disk array problems.
Updating the controller microcode
Disk drives attached to this RAID adapter must contain
the latest microcode level. Microcode can be updated using the iprconfig
utility.
Replacing the cache directory card
Replace the cache directory card only if you are directed
to do so by an isolation procedure or a maintenance analysis procedure
(MAP).
Physical disks
Replace failed disks as soon as possible,
even if a rebuild was initiated on a hot spare by the controller.
Disk failure recovery
The IBM® SAS
RAID controller handles disk failures differently, depending
on the RAID level involved.
Reclaiming IOA cache storage
A reclamation procedure for IOA cache storage is sometimes
used to resolve cache problems. Perform this procedure only if directed
to do so by a Maintenance Analysis Procedure (MAP).
