I'm not sure if we're on the same page - I know you're talking about "tape"
backups, but in real life, what you might think of as a "tape" backup could
very likely go to a disk staging unit used by your media management software
(TSM in your case, Netbackup in mine). As far as Oracle/RMAN is concerned this
is a "tape" backup through the sbt_tape device type, but really it's sitting on
disk until your media management software gets around to moving it off to tape
(which may even be never). This is a very common practice to improve the
performance of backups & restores due to the limited speed & capacity of tapes.
If this is the case in your environment, then you won't get a tape label in
your RMAN media column - you'll just get some mostly useless identifier for the
disk path that your media management software used for staging the backup.

Brandon

Thanks for the info. I'm aware of disk and tape backups. I'm talking
about tape backups.
