I assume you are using scratch tapes in your library for the pool where this 
data is heading.  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.

Subject: [ADSM-L] Backup files to empty tape

Hi list,

I have to backup some files from a TSM node to an empty tape and send this tape 
away (check out from the library). What is the best approach to perform this 
task?

Thanks

Mario
