Glossary
This glossary defines the terms used in this manual.
attribute. In DSM, a characteristic of an entity. For example, two attributes of a
communications line might be its baud rate and its retry count. In a token-oriented
interface based on SPI, an attribute of an object is usually expressed as either a simple
token or as a field within an extensible structured token.
BSD. Berkeley Software Distribution.
connection. The path between two protocol modules that provides reliable stream delivery
service. In the Internet, a connection extends from a TCP module on one machine to a
TCP module on another machine.
CRU. See customer-replaceable unit (CRU).
customer-replaceable unit (CRU). A subset of field-replaceable units (FRUs) that can be
installed and serviced (replaced) by customers, without using special tools or special
HP training. CRUs can be replaced while the system is running.
CONFIG. See system configuration database (CONFIG).
DEFINE. An HP Tandem Advanced Command Language (TACL) command you can use to
specify a named set of attributes and values to pass to a process.
DIH. See driver/interrupt handler (DIH).
Distributed Systems Management. A set of tools used to manage HP NonStop S-series
systems and EXPAND networks. These tools include the VIEWPOINT console
application, the Subsystem Control Facility (SCF) for data communications
subsystems, the Subsystem Programmatic Interface (SPI), the Event Management
Service (EMS), the Distributed Name Service (DNS), and token-oriented programmatic
interfaces to the management processes for various HP subsystems.
DNS (Domain Name Server). See Domain Name Server.
Domain. (1) In the Internet, a part of the naming hierarchy. Syntactically, a domain name
consists of a sequence of names (labels) separated by periods (dots).
(2) In a NonStop S-series server, a pair of service processors, the associated router
clouds, and the attached replaceable units.
(3) A set of objects over which control or ownership is maintained. Types of domains
include power domains and service processor (SP) domains.
Domain Name Server. A method for naming resources. The basic function of the domain
name server is to provide information about network objects by answering queries.
