Using SCF to Monitor the System

Use the Subsystem Control Facility (SCF) to display information and current status for

all the devices on your system known to SCF. Some SCF commands are available

only to some subsystems. The objects that each command affects and the attributes of

those objects are subsystem specific. This subsystem-specific information appears in a

separate manual for each subsystem. A partial list of these manuals appears in

Appendix C, Related Reading.

1-> STATUS TAPE $*
