C-2
Command Line Interface (CLI)
CLI commands enable you to automate testing or array creation in
a production environment using Windows command scripts and
Linux and UNIX shell scripts.
This appendix describes briefly some of the commands available in
the CLI. For a full description of all the CLI commands, refer to the
CLI Software Reference Guide.
Terminology
Your Serial ATA adapter has the following restrictions with regard
to CLI terminology and nomenclature:
■ Channel/LUN — Channel always equals 0; LUN always equals 0.
■ ID—“ID” always means “port.”
In other words, in the device ID format
C:PT:L , where C represents
Channel, PT represents Port, and L represents LUN, only the value
for Port is used.
The following terms are used in discussing the CLI:
■ Array, container — A logical disk created from available space and
made up of one or more segments on one or more physical disks.
■ Stripe, chunk—Contiguous set of data distributed across all the
disks in an array. A striped array distributes data evenly across
all members in equal-sized sections called stripes.
■ Free or available space—Space on an initialized disk that is not
in use.
■ Segment, partition—Contiguous area of a physical drive that
makes up some or all of an array.
■ Hot spare, failover disk—A hard drive, an array member, that
is not used in day-to-day data storage but is instead reserved for
use as a replacement for one of the other drives in the array in
the event of a failure.
Additional RAID terms are defined in the Glossary.
Accessing the CLI
The method you use to access the CLI depends on the operating
system, as described below.
