CLI Command Descriptions
308 HP StorageWorks HSG60 and HSG80 Array Controller and Array Controller Software
Command Line Interface Reference Guide
Converts a one-member mirrorset back to a nonmirrored disk drive and deletes the
mirrorset from the list of known mirrorsets. This command can only 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.
