belongs to a RAID Volume, the Volume goes Critical or Offline. See "Checking
RAID Volume Status in PASM" on page 117.
Replace the failed disk drive with a new disk drive of the same or slightly greater
capacity. You do not have to power down the SmartStor.

2. Pull out the drive carrier with the failed drive.
3. Remove the failed disk drive from the drive carrier.
4. Install a new disk drive into the carrier.
5. Place the carrier with the new disk drive back into the open slot in the
SmartStor.
If the failed drive belonged to a RAID Volume, the RAID Volume will begin
rebuilding as soon as the new drive is installed.
During the Rebuild, the Disk Status LED show amber. When the Rebuild is
finished, the Disk Status LED turns green.
If the replacement drive is free, that is, not assigned to a RAID Volume or as a
