Dell MD3200, MD3220 owner manual Select Physical disk→ Hot Spare Coverage, 112

•If there are secure disk groups and security capable disk groups in the storage array, the hot spare physical disk must match the security capability of the disk group.

•Hot spare physical disks must have capacities equal to or larger than the used capacity on the physical disks that they are protecting.

•The availability of enclosure loss protection for a disk group depends on the location of the physical disks that comprise the disk group. To make sure that enclosure loss protection is not affected, you must replace a failed physical disk to initiate the copyback process. See "Enclosure Loss Protection" on page 115.

CAUTION: If a hot spare physical disk does not have Optimal status, follow the Recovery Guru procedures to correct the problem before you try to unassign the physical disk. You cannot assign a hot spare physical disk if it is in use (taking over for a failed physical disk).
