You can set it type DISK but you will not get the results that you desire. Rman has no concept of TSM diskpool vs. tape - if you were to use type DISK the backup would go to your local disk (probably not what you want). I would recheck your management class settings for Oracle backups and make sure that they are indeed using the diskpool for it's destination, otherwise I would question your existing copygroup settings.
************************************************ Hi, I am taking backup from tdp client of Oracle database,RMAN type should be "sbt_tape"? is it possible to I can specify type DISK.I want backup should go to diskpool and then data should migrate to tapepool.My copygroup- copy distination is pointing diskpool,but at the time of backup,it is asking tape?
