initial software revision
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.
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

operating system) that manages the I/O functions for one or more ServerNet
addressable controllers (SACs) of the same type.
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

instructions from memory and executing them.
