Compaq HSZ80 manual 145, Unmirror DISK10300

5–145

UNMIRROR

Converts a one-member mirrorset back to a non-mirrored disk drive and deletes its mirrorset from the list of known mirrorsets. This command can be used only on mirrorsets already members of higher-level containers (stripesets or units).

The UNMIRROR command is not valid for disk drives having a capacity greater than the capacity of the existing mirrorset. If a mirrorset is comprised of disk drives with different capacities, the mirrorset capacity is limited to the size of the smallest member; larger members contain unused capacity. If a member with unused capacity is the last remaining member of a mirrorset, the UNMIRROR command cannot be used to change the disk drive back to a single-disk unit. This change would cause a change in the reported disk capacity, possibly corrupting user data.
