Recovering from defunct drives
If the defunct drives are not part of an array, contact your service representative.
If a physical drive fails in an array or multiple physical drives fail in separate
arrays (one physical drive per array), complete the following steps:
- Replace each defunct physical drive. The controller starts the
rebuild operation when it detects the removal and reinsertion of a drive that
is part of an array.
Note: (For a configuration
that contains a hot-spare drive) If you replace a failed physical drive, it
is not necessary to position the new physical drive on the same SCSI channel
and SCSI ID as the original hot-spare drive. The replacement physical drive
is automatically incorporated into the configuration as a hot-spare drive.
Here is an example of how this works:
- The original configuration consists of a RAID level-5 logical drive
composed of four physical drives. The physical drives are connected to
SCSI channel 1; they are assigned SCSI IDs 0, 1, 2, and 3. SCSI ID 3 is
a hot-spare drive.
- The physical drive at Channel 1, SCSI ID 2, fails; the logical drive
enters the critical state.
- The hot-spare drive at Channel 1, SCSI ID 3, is rebuilt into the array.
- You remove the failed physical drive at Channel 1, SCSI ID 2, and replace
it with a new physical drive. The new physical drive at Channel 1, SCSI
ID 2, is automatically assigned to be a hot-spare drive.
- If a rebuild operation is in progress, wait until the rebuild is complete.
Otherwise, go to step 3.
Note: If you are
replacing multiple defunct drives, you must wait for each rebuild operation
to complete before starting subsequent rebuild operations.
- Verify the cables, physical drives, and controllers are installed properly.
- Attempt to rebuild the defunct physical drive by performing
a hot-swap rebuild.
- If the hot-swap rebuild fails, contact your service representative.
