RAID Configuration and Management
Spare
The spare option in the utility assigns an extra, unused drive as a spare to be used in
case of a drive failure. The spare drive will not be used during normal system
operation, and provides no additional storage capacity. A pre-configured spare hard
drive will be brought into service only in the case of a RAID 1 failure.
IMPORTANT: The spare option is applicable only in RAID 1 for the server. If a spare is not
available, the failed drive must be replaced with a new drive so that the data on the failed drive
can be rebuilt. The replacement drive capacity must be greater than or equal to the failed drive
it replaces.
