MIRROR
Creates a one-member mirrorset from a single disk. This command is used only on
disks configured as units or members of a stripeset. Enter the ADD MIRRORSET
command to create a mirrorset from disk drives not already members of higher level
containers.
After the disk drive is converted to a mirrorset, increase the nominal number of
members by entering the SET mirrorset-name MEMBERSHIP=number-of-members
command, then enter the SET mirrorset-name REPLACE=disk-name command to
add more members to the mirrorset.
NOTE: This command is also valid for a REMOTE disk, resulting in a single member
mirrorset with DT_SUPPORT enabled.

naming convention presents to the user both the type of container and its unique
identifier.
