Use different tape category ranges for your NT server. There is a redbook
about it : Partitioning and Sharing 3494. This is a Partiotining situation.
All information needed is in the redbook.

On ADSM, define a diferent Private and Scratch catagory number than the one
the mainframe uses.

When you first insert tapes on the 3494, they are FF00. Query the inventory
and set the catagory number to the one you want for your ADSM scratch
volumes. Now ADSM can address, and your mainframe can't.

I don't know about NT. On AIX I used mtlib in a shell-script.

Good luck !
