Setting a Physical Drive as a Spare
NOTE: Spare drives serve as spares to all logical drives. They are not grouped with a
particular logical drive.
How a Spare Drive Works
■ If a physical drive fails in a RAID 1, RAID 0+1, RAID 4, or RAID 5
logical drive, the spare automatically replaces the failed physical drive
and the controller reconstructs all logical drives that contained the failed
physical drive as a member.
■ After the controller writes data to a spare, the spare becomes part of the
same device group in which a device failed.
■ After the controller writes data to a spare, the status of the spare changes
to Good.
To Define a Spare Physical Drive
1. In the main window of the Configuration Utility, click the physical drive
to be used as a spare. The physical drive must be in the Available state.
2. From the Storage menu, choose Physical Drive, then choose Make
Spare.
NOTE: The spare must have a capacity equal to or greater than the failed physical drive
for an automatic reconstruct to start.
