HP-UX System Administrator's Guide: Overview HP-UX 11i v3 (B3921-90011, September 2010)

major number The part of a device special file that determines whether the file is used for block access or
character access and also used to determine which device driver to use when communicating
with the device.
managed systems Any system managed by HP Systems Insight Manager, including servers, desktop PCs, and
Remote Insight Boards.
management
domain
A collection of resources called managed systems that have been placed under the control of
the HP SIM. Each Central Management Server is responsible for a management domain. The
managed systems can belong to more than one management domain.
See also Central Management Server.
metrocluster See metropolitan cluster.
metropolitan
cluster
A cluster that is geographically dispersed within the confines of a metropolitan area requiring
right-of-way to lay cable for redundant network and data replication components.
minor number The part of a device special file that identifies the location of the interface to which a device is
attached and defines driver-dependent characteristics. This information is organized by specific
bit assignments.
See also device special files and major number.
modules See kernel modules.
mount points Directories in the HP-UX directory tree where file systems are logically attached. When mounted,
the directory that is the root of a file system’s directory tree is represented by the HP-UX
directory to which it is mounted. See mount(1M).
network based
printer
A printer connected directly to a network and having its own network interface (such as an HP
JetDirect interface card) and network address. All printing to a network based printer must
travel over the network.
See also remote printer.
nodes (Serviceguard) Individual systems in a Serviceguard cluster. Systems could be standalone
servers or instances of HP-UX running in a partition on a server.
(Networking) (Individual instances of HP-UX (or other operating systems) on a network, each
identified by its own hostname and one or more IP addresses.
(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 cellular and Superdome 2 blade-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)
