I can ask you a bunch of questions that will keep you busy for a while
which I may have to ask eventially anyway, but if you can start by
describing the command sequence and associated messages I might be
able to help you without any more info.


Some of the questions I might need to know:

Did you define the drives using smit and the adsm device drivers?
        The command:
                lsdev -C -c tape -H

        should show something like this:
                mt0   Available 00-07-00-50 ADSM Tape Drive
                mt1   Available 00-07-00-60 ADSM Tape Drive

When you are doing the ADSM define drive are you using the /dev/mt0
and NOT the /dev/rmt0 special files?

Good luck...Jim
