pathname
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.
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.
