SYSGENR
SYSGENR. The system generation program that generates a customized version of the HP
NonStop™ Kernel operating system.
SYSnn subvolume. A subvolume on the $SYSTEM volume where the new version of the
HP NonStop™ Kernel operating system image is located. Also located on the SYSnn
subvolume is system-dependent and release version update (RVU)-dependent
software. nn is an octal number in the range %00 through %77.
SYSPOOL. The system data space that remains in memory after all system data structures
are built by the HP NonStop™ Kernel operating system at the time of a processor load.
system. All the processors, controllers, firmware, peripheral devices, software, and related
components that are directly connected together to form an entity that is managed by
one HP NonStop™ Kernel operating system image and operated as one computer.
See also node.
system area network management process. See external system area network manager
process (SANMAN).
system code. A logically distinct part of the HP NonStop™ Kernel operating system that
consists of operating-system procedures shared by all processors.
system configuration database. The database file on the $SYSTEM.ZSYSCONF
subvolume that contains configuration information for all system objects that can be
configured by the Subsystem Control Facility (SCF). Configuration information for all
system objects that can be configured during system generation is contained on the
$SYSTEM.SYSnn subvolume. See also configuration file and SYSnn subvolume.
system console. (1) A Compaq TSM workstation configured as the primary or backup
dial-out point. The TSM workstation configured as the primary dial-out point is called
the primary system console. The TSM workstation configured as the backup dial-out
point is called the backup system console. (2) In UNIX, an optional file such as
/dev/console that receives messages sent through certain application program
interfaces.
system enclosure. An enclosure for system components. Processor enclosures and I/O
enclosures are both system enclosures. Contrast with peripheral enclosure.
system engineer (SE). See service provider.
system expansion. The process of making a target system larger by adding enclosures to
it. The enclosures being added can be either new enclosures or enclosures from a
donor system. Contrast with system reduction.
system generation. The process of creating an operating system to support a particular
system configuration and software release version update (RVU).
