Compaq HSZ80 Array Controller ACS Version 8.3 Configuration and CLI Reference Guide
■ The replacement policy is set to NOPOLICY
■ The mirrorset is missing at least one member
NOTE: An error is displayed if you attempt to replace a REMOTE disk into a
NODT_SUPPORT mirrorset.
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 when it was added to the
configuration with the ADD DISK command.
NOTE: Do not specify any other switches when the REPLACE switch is specified.
POLICY=BEST_FIT
POLICY=BEST_PERFORMANCE (Default)
NOPOLICY
Sets the selection criteria the controller uses to choose a replacement disk from the
spareset when a mirrorset member fails. If DT_SUPPORT is enabled, NOPOLICY
must be selected.
Specify POLICY=BEST_FIT to choose a replacement disk drive from the spareset
that equals or exceeds the base member size (smallest disk drive at the time the
mirrorset was initialized). If there is more than one disk drive in the spareset that meet
the criteria, the controller selects a disk drive with the best performance. This switch
is not valid if DT_SUPPORT is enabled.
Specify POLICY=BEST_PERFORMANCE to choose a replacement disk drive from
the spareset with the best performance. The controller attempts to select a disk on a
different port than existing mirrorset members. If there is more than one disk drive in
the spareset matching the best performance criteria, the controller selects a disk drive
that equals or exceeds the base member size of the mirrorset. This switch is not valid
if DT_SUPPORT is enabled.
