Glossary–3
coax A two-conductor wire in which one conductor completely wraps the other
with the two separated by insulation.
cold swap A method of device replacement that requires the entire subsystem to be
turned off before the device can be replaced. See also hot swap and warm
swap.
command line
interpreter
(CLI) The configuration interface to operate the controller software.
concat 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 HSG60
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.
DAEMON Pronounced “demon.” A program usually associated with a UNIX systems
that performs a utility (housekeeping or maintenance) function without being
requested or even known of by the user. A daemon is a diagnostic and
execution monitor.
data center cabinet A generic reference to large Compaq subsystem cabinets, such as the cabinets
in which StorageWorks components can be mounted.
