Replace failed pdisks as soon as possible, even if a reconstruction
was initiated with a hot spare by the controller. The Replace/Remove
a Device Attached to an SCSI Hot Swap Enclosure Device option
in the SCSI and SCSI RAID Hot Plug Manager can be used to replace
failed pdisks. The IBM® SAS Disk Array Manager provides
a shortcut to the SCSI and SCSI RAID Hot Plug Manager.
Attention: Perform this procedure only if you
are directed from an isolation procedure or a maintenance analysis
procedure (MAP).
Note: The replacement disk should have a capacity
that is greater than or equal to that of the smallest capacity disk
in the degraded disk array.
Attention: Always use
the SCSI and SCSI RAID Hot Plug Manager for devices attached to an IBM SAS RAID Controller. Do not
use utilities intended for other RAID products, such as RAID Hot Plug
Devices.
