3.4.4 Spare Drive Management

If you have an unassigned disk drive, you can assign it as a spare drive. A
spare is a disk drive that has been designated to replace a failed disk drive in
a RAID Volume. In the event of the failure of a disk drive within a RAID 1 or
three drive RAID 5 Volume, the spare drive is activated as a member of the
RAID Volume to replace a disk drive that has failed.
A spare drive cannot replace the failed drive in a RAID 0 Volume because of
the way in which data is written to the disk drives under RAID 0. A spare drive
