PIC
PIC. See plug-in card (PIC).
PID. In the Open System Services (OSS) environment, a synonym for process ID. OSS
process ID is the preferred term in HP NonStop™ S-series system publications.
In the Guardian environment, PID is sometimes used to mean either:
•
A Guardian process identifier such as the process ID
•
The cpu, pin value that is unique to a process within a node (see HP NonStop™
Kernel user ID)
PIF. See physical interface (PIF).
PIN. See process identification number (PIN).
ping. A utility used to verify connections to one or more remote hosts. The ping utility uses
the Internet control message protocol (ICMP) echo request and echo reply packets to
determine whether a particular IP system on a network is functional. The ping utility is
useful for diagnosing IP network or router failures.
pipe. In the Open System Services (OSS) environment, an unnamed FIFO, created
programmatically by invoking the pipe() function or interactively with the shell pipe
syntax character (|). A shell pipe redirects the standard output of one process to
become the standard input of another process. A programmatic pipe is an
interprocess communication mechanism.
planned outage. Time during which a computer 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.
planner. The Distributed Systems Management/Software Configuration Manager
(DSM/SCM) user who is responsible for planning and managing new software
revisions. The planner uses the DSM/SCM Planner Interface to carry out these
functions.
Planner Interface. A graphical user interface (GUI) to the Distributed Systems
Management/Software Configuration Manager (DSM/SCM) that runs on the host
system. It provides an interface to all the host DSM/SCM planner functions.
plug-in card (PIC). A replaceable component that provides a unique function when
installed in a customer-replaceable unit (CRU) or field-replaceable unit (FRU). PICs
for modular ServerNet expansion boards (MSEBs) and I/O multifunction (IOMF) 2
CRUs provide a choice of connection media for attaching ServerNet cables.
PM. See product module (PM).
PMB. See processor and memory board (PMB).
