Typically in the AIX TSM server environments (can't speak for the others) it will use empty scratch volumes in the order they ~became~ empty/scratch be that from all the data expiring on it, reclamation, or checking into the library so if you had a "brand new tape" you specifically wanted used, you might have to do some additional activity... if you just wanted a fresh empty tape used... Kelly's description would work.
An alternate way to take specific files out of the library would be to: 1) if you don't have any other archive data for that node... archive the data and then do an export of the archive data and send that off 2) define an alternate node name for that node like <existing node name>_exp and backup or archive the files you need to have taken off site, then export that node to tape With the exports, you can specify private tapes or let it use scratch and it will pick an empty tape and only put the export data on it.

By default, TSM will choose one of the filling scratch tapes first. To make sure it uses a brand new tape, set all the filling tapes in that pool in that library to ReadOnly. Then start the backup to that pool. TSM will be forced to take another tape from scratch. Note the volser of the tape being used. When the backup is done, check that tape out and set the readonly tapes back to readwrite. There are variations on the theme but this will work. Make sure nothing else is going on during this or you might get other data on that tape.

What is the best approach to perform this task? Thanks Mario
