system image disk (SID)
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. 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.
system planner. The person who plans for the hardware and software installation of a new
system or for changes to a system already installed. This person arranges for site
preparation, schedules the installation, and completes the Installation Document
Packet.
system process. (1) A privileged process that comes into existence at system-load time
and exists continuously for a given configuration for as long as the processor remains
operable. (2) A HP NonStop™ Kernel operating system process, such as the memory
manager, the monitor, and the input/output (I/O) control processes. The files containing
system processes are invoked by ALLPROCESSORS paragraph entries. (3) A part of
a single copy of the HP NonStop Kernel operating system with Open System Services
(OSS) interfaces. A system process does not have an OSS process ID.
system reduction. The process of making a donor system smaller by removing enclosures
from it. The enclosures removed from a donor system might be added to a target
system. Contrast with system expansion.
