Using SCF to Configure and Manage
NonStop S-Series Servers
You use the Subsystem Control Facility (SCF) on G-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 a G-series RVU on a NonStop S-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
If you are migrating from a system running D-series, refer to Appendix C, D-Series and
G-Series Comparison and Migration, for more information.
The following topics are discussed in this section.
NonStop S-Series Configuration Architecture
Configuration and startup tasks for NonStop S-series servers differ from those for
earlier servers because the hardware architecture is based on different building blocks.
For example, the functions of the interprocessor bus and I/O channels on NonStop
K-series servers are performed on NonStop S-series servers by the ServerNet fabrics.
When you install a G-series RVU, DSM/SCM configures the system variables listed in
the CONFTEXT file. You load the system from one of the configuration files in the
$SYSTEM.ZSYSCONF subvolume. Then you perform all remaining configuration
tasks by using SCF.
