physical link interfaces
physical link interfaces. Communications standards defined by standards organizations.
These 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. One of several views of a server available in the view pane of the
Management window of the OSM Service Connection, TSM Service Application, and
OSM and TSM Low-Level Link. A Physical view of a server is a view of all the
enclosures and is intended to represent the actual floor plan at the site. A Physical
view of an enclosure is a visual representation of the physical placement of supported
resources inside the enclosure. See also Connection view
.
PIB. See power interface board (PIB).
PIC. (1) See plug-in card (PIC). (2) See position-independent code (PIC).
PID. In the Open System Services (OSS) environment, a synonym for process ID. OSS
process ID is the preferred term in HP NonStop™ 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 an Expand node (See
process identification number (PIN)
.)
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. (1) 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. (2) A person who participates in planning a new HP NonStop™ system.
