owner
owner. (1) In the case of a disk file, the user or program that created the file, or a user or
program to whom the creator has given the file with the File Utility Program (FUP)
GIVE command. (2) In the case of a process, the user or program that created the
process or, if the PROGID option was specified in the File Utility Program (FUP)
SECURE command for the code file, the user or program that owns the code file. (3) In
the case of a token or other definition, the subsystem that provided the definition. (4) In
the case of a subsystem, the company or organization that provides the subsystem, or the
eight-character string identifying that company.
passthrough terminator. See SCSI passthrough terminator
.
path. The route between a processor and a subsystem. If a subsystem is configured for fault
tolerance, it has a primary path (from the primary processor) and a backup path (from
the backup processor).
peer service processors. A pair of service processors (X and Y) in a service processor (SP)
domain. Peer service processors function similarly to a fault-tolerant process pair in a
Himalaya K-series system. See also service processor (SP)
.
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 releases to manage
disks and other peripheral devices. In G-series releases, PUP functions are performed by
the Subsystem Control Facility (SCF).
physical interface (PIF). The hardware components that connect a system node to a
network.
physical link interfaces. Communications standards defined by standards organizations. The
following physical link interfaces are supported for the ServerNet wide area network
(SWAN) concentrator: RS-232, RS-442, RS-449, V.35, and X.21.
physical view. A visual representation of the physical placement of customer-replaceable
units (CRUs) and field-replaceable units (FRUs) inside the set of enclosures in a group.
PIB. See power interface board (PIB)
.
PIC. See plug-in card (PIC)
.
PIF. See physical interface (PIF)
.
planned outage. Time during which a NonStop system is not capable of doing useful work
because of a planned interruption. A planned outage can be time when the system or
user application is shut down to allow for servicing, upgrades, backup, or general
maintenance.
