SHOWDEV 

The SHOWDEV command displays status information for all input and output
devices on the system.

Syntax 

SHOWDEV [ldev     ]
        [classname]
Parameters 

ldev                  Specifies the logical device number of the device
                      for which status information is to be displayed.
                      This number is unique for each device.  Without
                      this parameter or the classname parameter, the
                      system displays status information for all devices
                      on the system.

classname             Specifies the class name of device(s) for which
                      status information is to be displayed.  This name
                      can apply to several devices.  Without this
                      parameter or the ldev parameter, the system
                      displays status information for all devices on the
                      system.
