If you delete a primary volume TSM also deletes the data from the copy pool.  
If you mark a primary destroyed then you can recover from the copy pool.

Subject: [ADSM-L] Deleting primary storage volumes

If I do a "del vol xxxxxx discarddata=yes" on a primary storage pool volume, 
will TSM retain knowledge that the data still exists on a copypool volume?

If yes, is there a way to recreate the primary storage pool volume from the 
copy pool data?
