Command Line Interface Reference Guide
For each reduced mirrorset, there must be at least one remaining normal
member after the reduction. A normal member is one whose contents are the
same as the other members.
Unlike the REDUCE command, the REMOVE switch does not change the
nominal number of members in the mirrorset. If the mirrorset has a
replacement policy and there are acceptable disk drives in the spareset, the
controller adds disk drives from the spareset to the mirrorset to make the
actual number of members equal to the nominal number of members.
Note: Normalizing members exist only after you first create a mirrorset or after you
clear lost data on a mirrored unit. The controller recognizes the member as normal,
and all other original mirrorset members as
Normalizing . New data that is written to
the mirrorset is written to all members. The controller copies the existing data of the
normal member before the mirrorset was created to the normalizing members. The
controller recognizes the normalizing members as normal after all the blocks for the
normalizing member are the same.
REPLACE=disk-name
Instructs the controller to add a disk member to an existing mirrorset if the
following conditions are met.
■ The replacement policy is set to NOPOLICY.
■ The mirrorset is missing at least one member.
If these conditions are met, the disk drive specified by disk-name is added
to the mirrorset specified by mirrorset-name. The nominal number of
members does not change.
The disk name used is the name given to a disk as it was added to the
configuration with the ADD DISKS command.
Note: Do not specify any other switches if the REPLACE switch is specified.
Examples
To change the replacement policy of mirrorset MIRR1 to best fit, enter:
SET MIRR1 POLICY=BEST_FIT
