Command Line Interface Reference Guide
RUN (default)
NORUN
Controls unit 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 is completely flushed.
Note: Regardless of storageset type, the NORUN switch cannot be specified for units
that are partitioned.
Note: Specifying NORUN and then RUN to a unit also causes the subsystem
configuration to be updated to the selected disk unit.
WRITE_PROTECT
NOWRITE_PROTECT (default)
Specifies whether data contained on the selected unit can be overwritten.
■ Specify WRITE_PROTECT to prevent host write operations to the unit.
However, the controller can 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.
