Hi, John. First, if you don't have copies, you risk losing data if a tape goes bad.
Second, you can define a primary pool to be managed by DRM with: set drmprimstgpool primarypoolname Then you can get those ejected for you and put them in a closet, and you have your copypool to send offsite. You're much better off regarding maintaining data integrity. Third, as you archive into your diskpool, you don't have to go to primary tape pool first. You can copy your diskpool to copypool tape with: backup stgpool diskpool copypool You can then migrate diskpool to primary tape pool as per the Second point. Otherwise you'll have those primary versions cluttering up your diskpool.

In general- we want to write archive data (separate management classes and storage pools) to disk and then directly to a tape copy pool, and then eject the media out of the library for long term storage-- without having redundant copies of the archive data sitting in a primary tape pool.-- Are there any suggestions on how to accomplish this-- since you can only route disk pools to primary tape pools first? TSM 5.1 allows synchronous writes to disk/tape/copy pools, but for TSM 4.2 I'm hoping to find a simple solution-- All feedback is very much appreciated- - John
