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.
