Using SCF to Determine Your System
Configuration
SCF is one of the most important tools available to you as a system operator. SCF
commands configure and control the objects (lines, controllers, processes, and so on)
belonging to each subsystem running on the Integrity NonStop NS-series server. You
also use SCF to display information about subsystems and their objects.
SCF accepts commands from a workstation, a disk file, or an application process. It
sends display output to a workstation, a file, a process, or a printer. Some SCF
commands are available only to some subsystems. An overall SCF reference is the
SCF Reference Manual for H-Series RVUs. Subsystem-specific information appears in
a separate manual for each subsystem. For a partial list of these manuals, refer to
Appendix C, Related Reading.
More details about the functions of SCF appear in Subsystem Control Facility (SCF) on
page B-4.
SCF System Naming Conventions
SCF object names usually follow a consistent set of naming conventions defined for
each installation. HP preconfigures some of the naming conventions to create the
logical device names for many SCF objects.
System planning and configuration staff at your site likely will change or expand on the
preconfigured file-naming conventions that HP provides, typically by establishing
naming conventions for configuring such objects as storage devices, communication
processes, and adapters. These conventions should simplify your monitoring tasks by
making process or object functions intuitively obvious to someone looking at the object
name. For example, in your environment, tape drives might be named $TAPEn, where
n is a sequential number.
The SCF Reference Manual for H-Series RVUs lists naming conventions for SCF
objects, as well as HP reserved names that cannot be changed or used for other
objects or processes in your environment.
