CLI Commands B–151
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 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.
