Hi Patrick
TSM doesn't work that way. It works with expiration of data, but not tapes. What you could try is one of three things:
1.) Use only selective backups. This is not a good way to do it, because you will be transporting a lot of data at every backup occasion.
2.) Deleting the volume you wish to use as scratch, with the flag discard=yes.
3.) Setting the backup copygroup policysettings so that no file will be kept for more than 20 days(you need to discard the data before checkin in the tapes.
I guess what you are trying to do is to check in the tapes with status scratch. Before doing this, one of the above has to been done.

Subject: Policy and expiration
TSM'rs
I have a tape library with one drive and 4 weeks of tapes. I rotate the tapes every week and thought I had set the policy correctly but whenever I use the oldest tapes I'm unable to checkin some of the tapes because there's still "good" data on them. What should I change in order for the tapes to expire every three weeks automatically?
TIA
