SCF Reference Manual for the Storage Subsystem (G06.28+, H06.05+, J06.03+)

Glossary
$ZCNF The name of the configuration utility process.
$ZZSTO The name of the storage subsystem manager process.
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 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.
block A grouping of one or more system enclosures that an HP NonStop S-series system recognizes
and supports as one unit. A block can consist of either one processor enclosure, one I/O enclosure,
or one processor enclosure with one or more I/O enclosures attached.
boot A synonym for load. Load is the preferred term used in this and other HP NonStop S-series system
manuals. See load.
cache (cache
memory)
A small, fast memory holding recently accessed data designed to speed up subsequent access
to the same data. Cache memory is built from faster memory chips than main memory, and it is
most often used with process or main memory but also used in network data transfer to maintain
a local copy of data.
CE Customer engineer. See service provider.
checksum A generic term, meaning to add together (although the definition of add need not be a normal
arithmetic add) all of the data to produce a check word.
cold load A synonym for system load or load (in the case of single processor load). System load or load is
the preferred term in this and other HP NonStop S-series system manuals. See system load and
load.
