Hi Hadailton,

You should define two libraries:

one is that you have

other is something like:
      def library=manual libtype=manual
      def drive manual mtape device=/your device/

Then when you want to use the drive as a manual library you type:
     update devclass YOURCLASS library=manual

And to change back:
     update devclass YOURCLASS library=THEOLDONE


Hope that help
