Managing the Spare Pool
The spare pool lets you have one or more disk drives available for the reconstruction
of redundant arrays (Mirrored [RAID 1 and RAID 10] and Parity [RAID 3, RAID 4,
RAID 5, and RAID 50]) arrays. Once you assign a drive to the spare pool, it is not
available for use as an array member or as a dedicated spare.
If a pool spare is too small (smaller than an individual member in an array), the
controller cannot use it.
Adding a Spare to the Spare Pool
You can add up to eight drives to the spare pool to reconstruct any critical array on the
controller. After an array has started using a pool spare, other critical arrays are
prevented from using it. For a pool spare to be used, it must be at least as large as the
minimum drive size in the array.
