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, then 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.
Syntax
MIRROR disk-name mirrorset-name
Parameters
disk-name
Specifies the name of the disk to convert to a one-member mirrorset. The disk must be
part of a unit.
mirrorset-name
Assigns a name for the mirrorset.
IMPORTANT: It is common to name a mirrorset MIRRn, where n is a sequentially
assigned, unique identifier. Other naming conventions are acceptable, but this
naming convention presents to the user both the type of container and its unique
identifier.
