I/O adapter module (IOAM) enclosure
I/O adapter module (IOAM) enclosure. The sheet-metal carrier that is installed in a 19-
inch rack and contains the IOAM components.
Kernel subsystem. In H-series RVUs, the subsystem for configuration and management of
the Subsystem Control Facility (SCF) subsystem managers that are generic
processes, some system attributes, and the ServerNet X and Y fabrics.
Kernel subsystem manager process. The generic process that starts and manages other
generic processes, some system attributes, and the ServerNet X and Y fabrics in
G-series RVUs. The $ZZKRN Kernel subsystem manager process is started and
managed by the $ZPM persistence manager process. See also generic process.
LAN. See local area network (LAN).
LANMAN. See LAN manager (LANMAN) process.
LAN manager (LANMAN) process. The process provided as part of the ServerNet local
area network (LAN) Systems Access (SLSA) subsystem that starts and manages the
SLSA subsystem objects and the LAN monitor (LANMON) process and assigns
ownership of Ethernet adapters to the LANMON processes in the system. Subsystem
Control Facility (SCF) commands are directed to the LANMON processes for
configuring and managing the SLSA subsystem and the Ethernet adapters.
LANMON. See LAN monitor (LANMON) process.
LAN monitor (LANMON) process. The process provided as part of the ServerNet local
area network (LAN) Systems Access (SLSA) subsystem that has ownership of the
Ethernet adapters controlled by the SLSA subsystem.
LIF. See logical interface (LIF).
local area network (LAN). A network that is located in a small geographical area and
whose communications technology provides a high-bandwidth, low-cost medium to
which low-cost nodes can be connected. 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.
logical device name. The name assigned to an I/O process during its configuration. Other
processes use the logical device name when issuing OPEN, READ, WRITEREAD, and
CLOSE Guardian procedure calls to the I/O process.
logical device number. A number that identifies a particular I/O device in the system.
Logical device numbers are assigned to physical I/O devices.
logical interface (LIF). A process that allows an application or another process to
communicate with data communications hardware.
low-level link. A connection between the OSM client software running on a system console
and the master service processors (MSPs) on an HP Integrity NonStop™ NS-series
