• 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). To assign or unassign hot spare physical disks: 1 In the AMW, select the Physical tab. 2 Select one or more physical disks. 3 Perform one of these actions: • Select Physical disk Hot Spare Coverage. • Right-click the physical disk and select Hot Spare Coverage from the pop-up menu. The Hot Spare Physical Disk Options window is displayed. 4 Select the appropriate option, you can select: • View/change current hot spare coverage-to review hot spare coverage and to assign or unassign hot spare physical disks, if necessary. See step 5. • Automatically assign physical disks- to create hot spare physical disks automatically for the best hot spare coverage using available physical disks. • Manually assign individual physical disks-to create hot spare physical disks out of the selected physical disks on the Physical tab. • Manually unassign individual physical disks-to unassign the selected hot spare physical disks on the Physical tab. See step 12. 112 Configuration: Disk Groups and Virtual Disks
