HP-UX System Administrator's Guide: Overview

(Directory Tree) In the HP-UX directory tree, each directory, file, or link represents a node.
Similarly, HP-UX keeps track of I/O devices using a hierarchy where each component in a hardware
path (regardless of which addressing scheme is used) represents a node on the I/O tree.
nPartitions Available on cell based servers, nPartitions (also known as hard partitions) provide both operating
system and electrical isolation. If an operating system crash or hardware failure occurs in one
nPartition on a server, operating systems and hardware in other nPartitions on the same server
continue working, unaffected by the failure.
See also Virtual Partitions and Integrity VM guest.
OL* Pronounced “oh ell star”. Represents all of the On-Line hardware manipulations (the * represents
the UNIX wild-card character):
• OLA = On-line ADD
• OLD = On-line DELETE
• OLR = On-line REPLACEMENT
• OL* = All of the above
operating
environments
Operating environments are individual software products that deliver specific HP-UX 11i
configurations. Each operating environment is comprised of the "base" HP-UX 11i functionality,
commonly needed network drivers, and selected additional layered software products (ISU
Products). There are four operating environments in HP-UX 11i version 3:
• HP-UX 11i v3 Base Operating Environment – (BOE)
• HP-UX 11i v3 Virtual Server Operating Environment – (VS-OE)
• HP-UX 11i v3 High Availability Operating Environment – (HA-OE)
• HP-UX 11i v3 Data Center Operating Environment – (DC-OE)
partition A grouping of server resources dedicated to an instance of an operating system.
See also nPartition, virtual partition, Integrity VM guest.
persistent
device special
file
A device file for mass storage devices (usually disks), that is associated with a LUN hardware
path, and thus transparently supports agile addressing and multipathing. A persistent device
special, therefore, remains unchanged if the LUN it is associated with is moved from one host
bus adapter to another, or if a mass storage device fails and is replaced.
primary swap The initial location made available for paging operations during the system startup sequence.
Defined using the swapon command. See swapon(1M).
See also secondary swap.
print
destination
A queue associated with a printer or printer class. Many of the Line Printer Spooling System
commands, and other applications that provide printing services, use the a print destination to
identify which printer or group of printers to affect. See the manpages lpadmin(1M) and lpalt(1M).
See also printer class, Line Printer Spooling System and print queues.
print queues A queue within the Line Printer Spooling System associated with a printer or printer class, used
to hold print requests until they are printed.
print requests A print job submitted to the Line Printer Spooling System.
See also Line Printer Spooling System.
printer class A print queue representing a group of one or more printers; treated as a single print destination.
Print requests submitted to a printer class (when printed) will be sent to one of the available
printers defined in the class. The Line Printer Spooling System determines which printer is actually
used to print any given request in the class queue.
printer
interface
scripts
A script, used by the Line Printer Spooling System, to output print requests to a printer. When
defined in the Line Printer Spooling System, a printer interface script is created which is a copy
