Listing the Devices on Your System

Listing the Devices on Your System

A device is a physical component of a computer system that is used to communicate
with the outside world or to acquire or store data. Examples of devices are printers, disks
(volumes), disk drives, tape drives, controllers, processors, and terminals.

Use the Subsystem Control Facility (SCF) to display the configuration characteristics of
all the devices on your system. See the SCF Reference Manual for G-Series Releases for
complete information about SCF, its commands and options, and device types and
subtypes.

Use the SCF LISTDEV command to obtain device listings for all device types,
subtypes, and other device characteristics. For information about specific devices, such
as disks and tapes, use the SCF INFO and STATUS commands.

To list all the devices on your system, enter this command at your TACL prompt:

> SCF LISTDEV

The data shown in the report means:
