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.
