Licensed Internal Code. Programming that defines
logical operations on data.
LICTR. Licensed Internal Code trouble report.
local area network. A computer network located on a
user’s premises within a limited geographical area.
logo. An identifying statement.
media. Magnetic disks or tapes and compact disks
(CD).
Multi-adapter bridge domain. This is the set of all
card locations controlled by one multi-adapter bridge.
Multi-adapter bridge Function. This identifies a single
PCI adapter card location under an multi-adapter
bridge. The multi-adapter bridge function number is
part of the Direct Select Address for a PCI I/O adapter.
The multi-adapter bridge number and the
multi-adapter bridge function number together indicate
a unique card location connected to a given system PCI
bus. The bus number and the multi-adapter bridge
number and the multi-adapter bridge function number
together identify a unique PCI I/O resource in the
system.
MES. Miscellaneous equipment specification.
The process of either an upgrade of your existing
system or moving parts from an existing system to a
new system, are called miscellaneous equipment
specification (MES).
MFIOP. Multiple Function I/O Processor.
mirrored protection. A function that protects data by
duplicating all disk unit data on one storage unit in an
auxiliary storage pool to another storage unit in the
same auxiliary storage pool.
MSD. Main store dump.
MSIOP. Magnetic Storage I/O Processor.
Multi-adapter Bridge. This is a PCI bridge resource in
the I/O hardware which provides for the connection of
PCI adapters to the system PCI I/O bus. Each PCI
adapter connected under an multi-adapter bridge is
controlled individually by the multi-adapter bridge.
The multi-adapter bridge number identifies an
multi-adapter bridge on a given system PCI I/O bus
and is part of the Direct Select Address for a PCI I/O
adapter. The bus number and the multi-adapter bridge
number together identify a unique multi-adapter bridge
in the system.
network interface controller (NIC). Hardware that
provides the interface control between system main
storage and external high-speed link (HSL) ports.
OEM. Original equipment manufacturer.
odd/even bus pair. An optical link card supports a
pair of buses; one has an even number and the other
has an odd number (for example, bus 2 and 3).
optical redundancy. A second optical path used to
keep the system operational when a hardware failure
occurs.
overview. A general survey or summary.
PAR. Problem analysis and resolution.
PCC. Power control compartment.
PIP. Problem isolation procedure. Written information
used by service representatives to repair IBM
equipment. A problem isolation procedure contains
actions and yes/no questions that send the user to the
failing part of the equipment.
plenum. A space used for environmental air.
PM. Preventive maintenance.
pool. (1) A readily available supply. (2) A designated
place to store data.
power off. To turn off the power.
power on. To turn on the power.
primary link. The optical connection between a local
optical link card and a remote bus adapter card.
problem isolation procedure. Written information
used by service representatives to repair IBM
equipment. A problem isolation procedure contains
actions and yes/no questions that send the user to the
failing part of the equipment.
program temporary fix. A temporary solution to, or
bypass of, a problem in a licensed program.
PTF. Program temporary fix. A temporary solution to,
or bypass of, a problem in a licensed program.
reallocate. To allocate again.
restore. To return to an original value or image; for
example, to restore data to main storage from auxiliary
storage.
SAL. Service action log
SAVSYS tape. A tape that is generated by the SAVSYS
command, on which system data is recorded and
saved.
SCSI. Small Computer System Interface
SDIOP. Storage Device I/O Processor.
secondary link. The optical connection between two
remote bus adapter cards.
