Glossary
45xx disk. A disk drive that resides in slots 0 through 7 of a modular disk subsystem
outside of NonStop S-series system enclosures. The disk subsystem connects to the
server through a ServerNet/DA Adapter (SNDA).
6760 ServerNet device adapter (ServerNet/DA). See ServerNet device adapter
(ServerNet/DA).
ACL. See automatic cartridge loader (ACL).
action. An operation that can be performed on a selected resource.
adapter. See ServerNet adapter.
ADAPTER object type. The Subsystem Control Facility (SCF) object type for all adapters
attached to your system.
alternate path. A path not enabled as the preferred path. An alternate path can become a
primary path when a primary path is disabled. Contrast with primary path.
assumed object. The object type or object name specified by a Subsystem Control Facility
(SCF) ASSUME command. If an ASSUME command has been used to establish a
default object type and fully qualified default object name, and if that object type and
object name together refer to a valid object, then object-spec can be omitted
entirely from an SCF command, and the command is applied to the object known as
the assumed object.
attribute. For the Subsystem Control Facility (SCF), a characteristic of an entity. For
example, two attributes of a process might be its program file and its user ID. An
attribute is sometimes called a modifier.
automatic cartridge loader (ACL). A device that stores multiple 3480, 3490, or digital
audio tape (DAT) format cartridge tapes and loads them automatically, one at a time,
into a tape drive.
automatic configuration. The automatic assignment of magnetic disk attributes to an
internal disk drive when it is inserted into a slot. Also known as plug and play.
automatic disk changer. See robot.
BACKUP. A utility for HP NonStop servers that creates a backup copy of one or more disk
files on magnetic tape. See also RESTORE.
backup processor. A processor in the HP NonStop operating system that communicates
with the primary processor, allowing the processors to remain independent. A
component failure in one processor has no effect on any other processor. Contrast with
primary processor.
