local mount
reexport, and from these, any successions of reexported libraries. See also libList and
searchList
.
local mount. In the Network File System (NFS), a mount that attaches the fileset
associated with a server to the specified mount point within the local directory
hierarchy. The local mount is visible within the NFS subsystem and makes the files
associated with the server available through the path associated with the local mount
point.
local node. See local system.
local operator. The person who performs routine system operations, such as starting and
stopping the system, loading and unloading tapes, and changing the air filter. The local
operator is normally the operator of the asynchronous system console for the node.
See also operator
.
local processor. A processor in the same node as the ServerNet cluster monitor process
(SNETMON) that is reporting status about the processor.
local system. (1) An on-site system or a system that is geographically near the user or
operator. (2) From the perspective of a particular SNETMON, the system or node on
which that SNETMON is running. (3) From the perspective of a system console
operator, the system to which the operator is logged on. Contrast with remote system
.
logic board (LB). (1) See cluster switch logic board. (2) A printed wiring assembly (PWA)
on which computer circuits (chips and wiring) are mounted. One type of logic board is a
processor and memory board (PMB). Another type is a multifunction I/O board
(MFIOB).
logical device name. The name assigned to an I/O process during its configuration. Other
processes use the logical device name when issuing Guardian procedure calls to the
I/O process.
logical device number (ldev). For a device or named process, the index into the
destination control table (DCT)
; or more precisely, into the named resource list (NRL).
Each device or named process in the system has an ldev.
logical disk volume. A hardware device or device pair that provides persistent, highly
accessible storage for data on a medium that is either magnetic or optical.
logical interface (LIF). A process that allows an application or another process to
communicate with data communications hardware.
logical memory unit (LMU). A group of four memory units on an HP NonStop™ S-series
processor and memory board. Memory on a processor and memory board (PMB) is
divided into two LMUs. One LMU contains memory units in slots MS1 through MS4.
The other LMU contains memory units in slots MS5 through MS8. An LMU must have
memory units installed either in all of its slots or in none of its slots. See also memory
unit.
