SNAX/XF SCF Commands When a system cold load completes, the line is in a stopped (offline) state. Use the
Subsystem Control Facility (SCF) to define and start the line and its physical and
logical units.
Use the SCF ADD command to define the entities. Once they are defined, use the SCF
START command to start them. For detailed information, refer to the Subsystem
Control Facility (SCF) Reference Manual.
Note If you have been using the Communications Management Interface (CMI), you will probably have to
modify your existing command files to be compatible with SCF. The SCF command language is similar to
that of CMI, but it is different; examine your command files closely.
