Compaq HSG80 Array Controller ACS Version 8.4 Configuration and CLI Reference Guide
NOTE: No other switches can be set when you specify the MEMBERSHIP switch.
If you increase the number of members and specify a replacement policy with the
POLICY= switch, the controller automatically adds disk drives from the spareset to
the mirrorset until the new number of members is reached, or there are no more
suitable disk drives in the spareset.
If you increase the number of members and the NOPOLICY switch is specified, the
REPLACE=disk-name switch must be specified to bring the mirrorset up to the new
nominal number of members.
You cannot set the nominal number of members lower than the actual number of
members. Specify the REMOVE switch to reduce the number of disk drives from the
mirrorset.
REMOVE=disk-name
Instructs the controller to remove a member from an existing mirrorset. The disk drive
specified by disk-name is removed from the mirrorset specified by mirrorset-name.
The removed disk drive is added to the failedset.
NOTE: No other switches can be set when the REMOVE= switch is specified.
If the mirrorset won’t have a normal or normalizing member remaining after you
remove the disk drive, the controller reports an error and no action is taken. A normal
or normalizing member is a mirrorset member whose contents are the same as all
other normal members.
For each reduced mirrorset, there must be at least one remaining normal member after
the reduction.
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.
