operator message

operator message. A message, intended for an operator, that describes a significant event

on a HP NonStop S-series system. An operator message is the displayed-text form of

an Event Management Service (EMS) event message. See also event message.

OSM. Stands for HP Open System Management (OSM) Interface. Replaces TSM as the

system management tool of choice for NonStop servers. Provides the same

functionality as TSM while overcoming limitations of TSM. OSM is required for support

of new functionality released in G06.21 and later.

peripheral enclosure. An enclosure that contains components related to one or more

peripherals. The 519x tape subsystem is an example of a peripheral enclosure.

Peripheral enclosures are not part of the set of system enclosures. Contrast with

system enclosure.

Peripheral Utility Program (PUP). A utility used in D-series and earlier RVUs to manage

disks and other peripheral devices. In G-series RVUs, PUP functions are performed by

the Subsystem Control Facility (SCF).

PIN. See process identification number (PIN).

PMF CRU. See processor multifunction (PMF) CRU.

PMF 2 CRU. See processor multifunction (PMF) 2 CRU.

POOL object type. The Subsystem Control Facility (SCF) object type for Storage

Management Foundation (SMF) storage pools. See also Storage Management

Foundation (SMF).

primary path. A path enabled as the preferred path. When a primary path is disabled, an

alternate path becomes the primary path. Contrast with alternate path.

primary processor. The processor that is designated as owning the ServerNet addressable

controller (SAC) connected to separate processors running the HP NonStop operating

system. The primary processor is the processor that has direct control over the SAC.

Contrast with backup processor.

process. A program that has been submitted to the operating system for execution, or a

program that is currently running in the computer.

process ID. A number that uniquely identifies a process. It consists of the processor (CPU)

number and the process identification number (PIN).

process identification number (PIN). A number that uniquely identifies a process running

in a processor. The same number can exist in other processors in the same system.
