NonStop System Glossary

computer-room power center (CRPC)
The equipment that conditions and distributes facility power to computer-room equipment. The
CRPC typically houses an electrostatically shielded isolation transformer, power distribution panels
(PDPs), a main shunt-trip circuit breaker, and voltage indicators. Also referred to as a power
distribution unit (PDU) or power distribution center.
concentrator manager process (ConMgr)
A process provided as part of the wide area network (WAN) subsystem. The ConMgr process
runs in each processor that supports WAN products and provides management functions to the
WAN subsystem and WAN products, such as downloading data link control (DLC) tasks to the
communications line interface processors (CLIPs) on the ServerNet wide area network (SWAN)
concentrator and selecting the preferred path for the DLC tasks.
conduit
A tubular raceway, usually constructed of rigid or flexible metal, through which insulated power
and ground conductors or data cables are run. Nonmetallic conduits, although available, are not
recommended.
CONFAUX file
The auxiliary configuration file created by the Distributed Systems Management/Software
Configuration Manager (DSM/SCM) tools. The CONFAUX file contains a list of the code files and
system files that are needed to build the new NonStop operating system. HP recommends that you
avoid making any changes to your CONFAUX file.
CONFBASE file
The basic system configuration database file, which is stored on the $SYSTEM.SYSnn subvolume.
See also configuration file.
CONFIG file
The current system configuration database file, which is stored on the $SYSTEM. ZSYSCONF
subvolume. See also configuration file.
configuration
1. The arrangement of enclosures, system components, and peripheral devices into a working
unit.
2. The definition or alteration of characteristics of an object.
configuration file
One of these files: CONFBASE, CONFIG, one or more saved configuration files named CONFxxyy,
and CONFSAVE. See also system configuration database.
configuration planner
The person who manages system configuration changes and software configuration changes. This
person modifies the system configuration database for system configuration changes and creates
a new operating system image for software configuration changes. See also planner.
configuration revision
A planner-defined set of software products and related configuration information that the Distributed
Systems Management/Software Configuration Manager (DSM/SCM) can activate on a target
system. Multiple configuration revisions might exist on a target system. A configuration revision is
