Using SCF to Configure and Manage
NonStop Integrity NS-Series Servers
You use the Subsystem Control Facility (SCF) on H-series systems to configure,
control, and display information about configured objects within each subsystem. Each
subsystem responds to and processes SCF commands that affect that subsystem. If
you are a super-group user (255, n ), you can use the SCF command-line user interface
to make configuration changes from any connected terminal.
When you install an H-series RVU on a Integrity NonStop NS-series server, the system
disk and a few other initial system-load processes are preconfigured. The CONFTEXT
file establishes some system attributes for all processors. You finish the rest of the
system configuration by using SCF.
Using SCF commands, you can:
•
Add, alter, or delete objects (such as devices, I/O processes, and generic
processes)
•
Obtain configured or current information about objects
•
Alter some system variables
These topics are discussed in this section.
Configuration Architecture for Integrity
NonStop NS-Series Servers
Each H-series operating system has multiple subsystems that handle the configuration
and management of subsystem-specific generic processes, I/O processes, and system
hardware. Figure 1-1 gives an overview of these configuration components. Each
component is explained below.
