RUN (Default)
NORUN
Controls the unit’s availability to the host.
Specify RUN to make a unit available to the host.
Specify NORUN to make a unit unavailable to the host and to cause any data in cache
to be flushed to one or more drives. NORUN spins down all the disks used in the unit.
The drives making up the unit spin down after the data has been completely flushed.
NOTE: Do not specify the RUN and NORUN switches for partitions.
WRITE_PROTECT (Default)
NOWRITE_PROTECT
Tells the controller whether data contained on the unit can be overwritten.
Specify WRITE_PROTECT to prevent host write operations to the unit. However, the
controller may still write to a write-protected RAIDset to satisfy a reconstruct pass or
to reconstruct a newly replaced member. Additionally, metadata, reconstruct, and
copy writes are still allowed to RAIDsets and mirrorsets.
Specify NOWRITE_PROTECT to allow the host to write data to the unit. This allows
the controller to overwrite existing data. NOWRITE_PROTECT is the default for
transportable disks.
WRITEBACK_CACHE (Default)
NOWRITEBACK_CACHE
Enable or disable the write-back data caching function of the controller. The
controller’s write-back caching feature improves write performance.
NOWRITEBACK_CACHE is the default on transportable disks.
