Terminology; Accessing The Cli - Adaptec RAID 21610SA Installation And User Manual

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.
I
ID—"ID" always means "port."
I
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
I
made up of one or more segments on one or more physical disks.
Stripe, chunk—Contiguous set of data distributed across all the
I
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
I
in use.
Segment, partition—Contiguous area of a physical drive that
I
makes up some or all of an array.
Hot spare, failover disk—A hard drive, an array member, that
I
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.
