HP-UX System Administrator's Guide: Overview

Glossary
accept
One of four commands that control the flow of print requests through the Line Printer Spooling
System (spooler). accept instructs the spooler to allow new print requests to be added to the
print queue of a printer or class.
See also reject, enable, disable.
Agile View A view of the I/O device tree using the more flexible and scalable persistent device special files,
LUN hardware paths.
See also Legacy View.
ASCII American Standards Committee on Information Interchange. A standard used by computers for
interpreting binary numbers as characters.
block special
files
See device special files.
board A printed circuit assembly (PCA). Also called a card or adapter.
boot loader A software program, used in the boot sequence, to load the HP-UX kernel from disk and start it
running.
bus A common data path over which data is transported.
cell A circuit board that contains processors and memory, all under the control of a cell controller
(CC) chip.
cell board See cell.
Central
Management
Server
A system in the management domain that executes the HP Systems Insight Manager software.
All central operations within HP Systems Insight Manager are initiated from this system.
character
special files
See device special files.
cold install Installation of a fresh copy of HP-UX to either a blank disk device or disk volume or completely
overwriting any previous contents on the device or volume — specifically, not an update.
compartments Compartments are a method for isolating components of the system from one another. When
configured properly, they can be effective in safeguarding HP-UX, its processes, and its resources.

rights
See iCAP components.
continental
cluster
A group of clusters that use routed networks or common carrier networks for data replication
and cluster communication to support package failover between separate clusters in different
data centers. Continental clusters are often located in different cities or different countries and
can span 100s or 1000s of miles.
core Formerly referred to as a “CPU”. An individual processing unit on a processor chip. Sometimes
referred to as a “processing core”.
device
multipathing
Used with agile addressing and persistent device special files, device multipathing allows multiple
hardware paths to a device to use a single device special file. Using device multipathing, you can
balance traffic loads between the various hardware paths to a device. You also have redundancy
should one of the paths fail.
device special
files
Associated with physical and pseudodevices, device special files are used by the operating system
and applications to write to and read from their associated devices.
