CLI Commands B–133
SET RAIDset-name
Changes the characteristics of a RAIDset.
Syntax
SET RAIDset-name
Parameters
RAIDset-name
Specifies the name of the RAIDset to modify. This is the name used
with the ADD UNIT command to identify the RAIDset as a host-
addressable unit.
Switches
POLICY=BEST_FIT
POLICY=BEST_PERFORMANCE (Default)
NOPOLICY
Specifies the replacement policy to use when a member within the
RAIDset fails.
Specify 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 RAIDset was initialized). If more than one disk
drive in the spareset is the correct size, the controller selects a disk
drive having the best performance.
Specify POLICY=BEST_PERFORMANCE to choose a replacement
disk drive from the spareset resulting in the best performance of the
RAIDset. The controller attempts to select a disk on a different port
than existing members. If more than one disk drive in the spareset
matches the best performance criteria, the controller selects a disk drive
that equals or exceeds the base member size of the RAIDset.
Specify NOPOLICY to prevent the controller from automatically
replacing a failed disk device. This causes the RAIDset to operate in a
reduced state until either POLICY=BEST_PERFORMANCE or
POLICY=BEST_FIT is selected, or a member is manually replaced in
the mirrorset.
