system enclosure
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 entry point table (SEP table). A table used on TNS systems that stores the XEP 
entry value for each TNS operating system procedure entry point. 
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).
system image disk (SID). A disk copy of the HP NonStop™ Kernel operating system 
produced during system configuration. The DISKGEN utility copies operating system 
files to the SID.
system image tape (SIT). A tape that can be used to perform a system load on a system if 
the system subvolume has become corrupted on both $SYSTEM disks. The tape 
contains a minimum set of software necessary to bring up and run the system. Use 
the SIT only for disaster recovery; it is not needed for normal system load. Contact the 
Global Customer Support Center (GCSC) before loading the system from a SIT; many 
additional steps are required to restore your system to working order. See also tape 
load.
system interrupt vector (SIV).  A HP NonStop™ Kernel operating system data structure 
that contains the addresses of interrupt handlers, parameters passed to interrupt 
handlers by special interrupt microcode, and other interrupt processing information.
System Library (SL). See TNS code space.
system library. A logically distinct part of the HP NonStop™ Kernel operating system that 
consists of user-callable library procedures and kernel procedures.
system load. (1) To start the system; to load the HP NonStop™ Kernel operating system 
image into the memory of a processor. See RELOAD. (2) The process of loading the 
operating system. A system load changes a system from an inactive to an active (or 
operational) state by loading software that establishes communication between the 
operating system and configured system peripherals.
system-managed process. Another name for a generic process.
system manager. See manager.
system number. See Expand node number.
system operator. See local operator and remote operator.
