Configuring Hot Spare Physical Disks

Guidelines to configure host spare physical disks:

•You can use only unassigned physical disks with Optimal status as hot spare physical disks.

•You can unassign only hot spare physical disks with Optimal, or Standby status. You cannot unassign a hot spare physical disk that has the In Use status. A hot spare physical disk has the In Use status when it is in the process of taking over for a failed physical disk.

•If a hot spare physical disk does not have Optimal status, follow the Recovery Guru procedures displayed by the MDSM application to correct any problem before trying to unassign the physical disk.

•Hot spare physical disks must be of the same media type and interface type as the physical disks that they are protecting.

•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 117.

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).

To assign or unassign hot spare physical disks:

1In the AMW, select the Physical tab.

2Select one or more physical disks.

3Perform one of these actions:
