NonStop System Glossary

initial software revision
The software revision on a target system when it is first brought into the Distributed Systems
Management/Software Configuration Manager (DSM/SCM) environment. The DSM/SCM host
database must be initialized with information about the initial software revision. The initial software
revision is then used as a baseline upon which new software revisions are based.
initialization
The process of defining a new Distributed Systems Management/Software Configuration Manager
(DSM/SCM) target system, including giving it a name, setting up default values used when
processing requests, and creating the first software revision (list of products) for the system.
inode
A data structure that stores the location of an Open System Services (OSS) file.
inode number
A unique identifier within the Open System Services (OSS) file system of an instance of an OSS
file. The inode number identifies the instance within the file system catalogs.
input source
The resource from which Subsystem Control Facility (SCF) accepts command input. SCF can accept
input from a terminal or a disk file. The initial input source is determined by the form of the RUN
command used to initiate SCF. At any time during an SCF session, the input source can be
temporarily changed to execute a series of commands from a command file.

or more ServerNet addressable controllers (SACs) of the same type.

directive. The Inspect region is sometimes called the symbols region.
INSPSNAP

installation subvolume (ISV)
A subvolume containing files that perform a specific function during the installation process, such
as organizing documentation in a specific location, providing the components of the NonStop
operating system image (OSIMAGE), and containing files that are used after the installation process.
installer
The person who installs the system equipment for a new system. This person also installs new
equipment when additions are made to the system. This person can install software and perform
system verification procedures as directed by the system planner, configuration planner, or support
