Configuration: Disk Groups and Virtual Disks 127
• 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 130.
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).
