parent process ID
parent process ID. In the Open System Services (OSS) environment, an attribute of a child
process determined by the parent process. The parent process ID is the OSS process
ID of the current parent process.
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).
pathname. In the Open System Services (OSS) file system and Network File System
(NFS), the string of characters that uniquely identifies a file within its file system. A
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.
PDC. See phase-loss detector/contactor (PDC).
PDP. See power distribution panel (PDP).
PDU. See computer-room power center (CRPC).
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. Peer service processors function similarly to a fault-tolerant process pair
in an HP NonStop™ K-series system. 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.
