RAID Configuration and Management
Spare
The spare option is not supported by the ProLiant DL320 Generation 2 server or the
Integrated ATA RAID Configuration Utility. This 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.

models of the server. This section details the features of the utility, including how to
