command line
interface
CLI. A command line entry utility used to interface with the HS-series
controllers. CLI enables the configuration and monitoring of a storage
subsystem through textual commands.

commands
Concat commands implement storageset expansion features.
configuration
file
A file that contains a representation of a storage subsystem
configuration.
container
1) Any entity that is capable of storing data, whether it is a physical
device or a group of physical devices. (2) A virtual, internal controller
structure representing either a single disk or a group of disk drives
linked as a storageset. Stripesets and mirrorsets are examples of
storageset containers the controller uses to create units.
controller
A hardware device that, with proprietary software, facilitates
communications between a host and one or more devices organized in
an array. The HSG80 family controllers are examples of array
controllers.
copying
A state in which data to be copied to the mirrorset is inconsistent with
other members of the mirrorset. See also normalizing.
copying
member
Any member that joins the mirrorset after the mirrorset is created is
regarded as a copying member. Once all the data from the normal
member (or members) is copied to a normalizing or copying member,
the copying member then becomes a normal member. See also
normalizing member.
CSR
An acronym for control and status register.
