file name
file name. A string of characters that uniquely identifies a file.
In the PC environment, file names for disk files normally have at least two parts (the
disk name and the file name); for example, B:MYFILE.
In the Guardian environment, disk file names include a node name, volume name,
subvolume name, and file identifier; for example, \NODE.$DISK.SUBVOL.MYFILE.
In the Open System Services (OSS) environment, a file is identified by a pathname; for
example, /usr/john/workfile.
firmware. A set of instructions written into the nonvolatile read-only memory (ROM) of a
host printed wiring assembly (PWA) when it is assembled and which persists in the
PWA in the absence of power. Firmware controls device boot and power-on diagnostic
functions. There are two types of firmware: read-only firmware, which is burned into
memory chips at the time of their manufacture, and updatable firmware, which resides
in writable memory (flash PROM or EEPROM). Firmware is also known as nonvolatile
microcode.
FRU. See field-replaceable unit (FRU).
HP NonStop Kernel. The operating system for HP NonStop servers.
HP NonStop™ Open System Management (OSM) software. Replacement for the
Compaq TSM package as the system management tool of choice for NonStop S-series
servers. OSM provides the same functionality as TSM while overcoming limitations of
TSM. OSM is reguired to support new functionality released in G06.21 and subsequent
RVUs.
indicator lights. Two lights on a customer-replaceable unit (CRU) that indicate the status of
the unit. The red or amber indicator light is lit when the unit is not working properly;
during startup, this light can indicate that the unit is not yet functioning. The green
indicator light is lit when the unit has proper power applied. See also light-emitting
diode (LED).
LAN. See local area network (LAN)
.
LED. See light-emitting diode (LED).
light-emitting diode (LED). A semiconductor device that emits light from its surface.
Indicator lights are composed of LEDs. See also indicator lights
local area network (LAN). (1) The cables, electrical interfaces, workstations, and other
devices that are interconnected and that are physically located in close proximity to
each other. One or more LANs can be connected to the system such that the LAN
users can access the system as if their workstations were connected directly to it. (2) A
network that is located in a small geographical area, whose communications
technology provides a high-bandwidth, low-cost medium to which low-cost nodes can
be connected.
