FIR
FIR. See FRU information record (FIR).
FIRINIT. A diagnostic task used to update the communications line interface processor
(CLIP) FRU information record (FIR) that is kept in the ServerNet wide area network
(SWAN) concentrator communications line interface processor (CLIP) flash memory.
FIRMUP. A diagnostic task used to update the copy of the Portable Silicon Operating
System (pSOS) system product embedded kernel that is kept in the ServerNet wide
area network (SWAN) concentrator communications line interface processor (CLIP)
flash memory.
firmware. Code in memory that is necessary for the power-up initialization and
communication with a host or device. The software for components of the ServerNet
architecture (for example, an adapter) is called firmware. Some firmware for ServerNet
components is downloaded when the system or component is loaded.
fixed process configuration. Using Subsystem Control Facility (SCF) to configure a
generic process to always start in the first available processor (that is, to be fault
tolerant).
flag. In a UNIX or Open System Services (OSS) command, a character sequence that
begins with a hyphen and is processed as a unit.
flash memory. A type of memory that contains essential firmware and nonessential
firmware.
flash PROM. A type of programmable read-only memory (PROM) that is electrically
reprogrammable.
flat segment. A type of logical segment. Each flat segment has its own distinct address
range within the process address space that never overlaps the range of any other
allocated segments. Thus all allocated flat segments for a process are always available
for use concurrently. See also logical segment and selectable segment.
flexible disk configuration (FDC). For HP NonStop™ S-series servers, a configuration of
an internal mirrored disk volume such that no single processor enclosure or I/O
enclosure can result in loss of online access to the volume.
foreground process. An Open System Services (OSS) process that belongs to a
foreground process group.
foreground process group. In the Open System Services (OSS) environment, a process
group whose members have privileges for access to their controlling terminal that are
denied to processes in background process groups of that terminal. Each session with
a controlling terminal has only one foreground process group for that terminal. Contrast
with background process group.
foreground process group ID. In the Open System Services (OSS) environment, the
process group ID of a foreground process group.
