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.

"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?
