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 partitions 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.
■ Partition—Contiguous area of a physical drive that makes up
some or all of an array.
■ Hotspare, 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.
