event message
event message. Text intended for a system operator that describes a change in some
condition in the system or network, whether minor or serious. The change of condition
is called an event. Events can be operational errors, notifications of limits exceeded,
requests for actions needed, and so on. See also operator message.
fabric. Describes a complex set of interconnections through which there can be multiple
and (to the user) unknown paths from point to point. The term “fabric” is used to refer
to the X or Y portion of the ServerNet system area network (ServerNet SAN); for
example, X fabric.
fault tolerance. The ability of an HP NonStop system to continue processing despite the
failure of any single software or hardware component within the system.
FCSA. See Fibre Channel ServerNet adapter (FCSA).
FC switch. See Fibre Channel switch (FC switch).
field-replaceable unit (FRU). A unit that can be replaced in the field only by qualified
personnel trained by HP and cannot be replaced by customers. A unit is classified as a
FRU because of safety hazards such as weight, size, sharp edges, or electrical
potential; contractual agreements with suppliers; or national or international standards.
Fibre Channel ServerNet adapter (FCSA). A ServerNet adapter that transmits data
between an HP NonStop™ server and Fibre Channel storage devices. This ServerNet
adapter is installed in an IOAM enclosure.
Fibre Channel switch (FC switch). Networking hardware that can connect an Enterprise
Storage System and an HP NonStop™ server. This switch allows any-to-any
connectivity.
filler panel. A blank faceplate that is installed in place of a ServerNet adapter or plug-in
card (PIC) to ensure proper ventilation.
file name. A unique name for a file. File names for disk files normally have at least two parts
(the disk name and the file name); an example of a file name on a PC is B:MYFILE. In
the Guardian environment on NonStop S-series systems, disk file names include a disk
volume name, a subvolume name, and a file identifier. An example of a file name on a
NonStop S-series system is $DISK.SUBVOL.MYFILE. For files that are network
accessible, the node name precedes the volume name:
\NODE.$DISK.SUBVOL.MYFILE.
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.
FRU. See field-replaceable unit (FRU).
