RAIDset 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 RAIDset.
■ Specify NOPOLICY to prevent the controller from automatically
replacing a failed disk device. This RAIDset operates in a Reduced state
until you select either POLICY=BEST_PERFORMANCE or
POLICY=BEST_FIT, or manually place a member in the RAIDset. See
SET RAIDset-name for more information regarding this procedure.
RECONSTRUCT=FAST
RECONSTRUCT=NORMAL (default)
Sets the speed at which the controller reconstructs data to a new RAIDset disk
that replaces the failed disk:
■ Specify FAST to allow the reconstruct process to take precedence over
other controller operations. If the RECONSTRUCT=FAST switch is
specified, the controller uses more resources to perform the
reconstruction. Reconstruction takes less time, but overall controller
performance is reduced during reconstruction.
■ Specify NORMAL to balance other controller operations with the
reconstruct operation. The controller uses relatively few resources to
perform the reconstruct process, and there is little impact on controller
performance.
REDUCED
NOREDUCED (default)
Permits the addition of a RAIDset that is missing a member (due to a failure):
■ Specify REDUCED if you add a reduced RAIDset (a RAIDset that is
missing one member).
Note: Verify that the RAIDset contains all but one of its disks before specifying the
REDUCED switch.
■ Specify NOREDUCED if all the disks making up the RAIDset are
present—for instance, while creating a new RAIDset.
