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.
command. A demand for action by or information from a subsystem or the operation
demanded by an operator or application. A command is typically conveyed as an
interprocess message from an application to a subsystem.
command file. An EDIT file that contains a series of commands and serves as a source of

Compaq TSM. Identifies a client or server software component used to manage or service
HP NonStop S-series servers.
Compaq TSM package. A software product for HP NonStop S-series servers that provides
the information needed to perform functions such as querying resources and testing,
provides notification of problems on the system, and allows local or remote access to
the system for service and maintenance. The TSM package performs the same role
as that of HP Tandem Maintenance and Diagnostic System (TMDS), Syshealth, and
Remote Maintenance Interface (RMI) on earlier systems.
CONFIG file. In G-series RVUs, the current system configuration database file, which is
stored on the $SYSTEM. ZSYSCONF subvolume. See also configuration file.
configuration. The definition or alteration of characteristics of an object.
configuration file. In G-series RVUs, one of these files: CONFBASE, CONFIG, one or
more saved configuration files named CONFxxyy,and CONFSAVE. See also system
configuration database. In pre-G-series RVUs, the configuration file is either the
OSCONFIG file used by the Configuration Utility Program (COUP) or the CONFTEXT
file used by SYSGENR.
