pathname component
pathname can be either relative or absolute. See also ISO/IEC IS 9945-1:1990
(ANSI/IEEE Std. 1003.1-1990 or POSIX.1), Clause 2.2.2.57.
pathname component. See filename.
pathname resolution. In the Open System Services (OSS) environment, the process of
associating a single file with a specified pathname.
pathname-variable limits. Limits that can vary within the Open System Services (OSS) file
hierarchy; that is, the limits on a pathname variable that can vary according to the
directory in which pathname resolution begins.
path prefix. In the Open System Services (OSS) environment, a pathname with an optional
final slash (/) character that refers to a directory.
PDP. See power distribution panel (PDP).
PDU. See power distribution unit (PDU).
peak load current. The maximum instantaneous load over a designated interval of time.
PEEK. A utility program that reports statistics on resource use in a processor. PEEK is used
to ensure proper allocation of memory and processes in a system after system load.
peer fabric. The fabric on which an operation is not taking place. The X and Y fabrics are
peers. If an action is being performed on one fabric, the other fabric is the peer fabric.
peer service processors. A pair of service processors (X and Y) in a service processor
(SP) domain. See also service processor (SP).
pending incident report. An incident report that has never been delivered to your service
provider, either because delivery to both the primary and backup dial-out points was
unsuccessful or because the incident report was generated at an unattended site.
pending signal. A signal that has been generated for a process but has not been delivered.
Pending signals are usually blocked signals.
periodic incident report. A type of incident report that is generated periodically to test the
connection to the service provider and report the current system configuration. The
default frequency is 20 days.
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 release version
updates (RVUs) to manage disks and other peripheral devices. In G-series RVUs,
similar functions are performed by the Subsystem Control Facility (SCF).
