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.

To add a pool spare:

1From the System Menu, select Pool Spare Menu and press Enter. The Pool Spare Menu screen displays.
