I haven't experienced that myself.
If that were true, RMAN would be unable to restore.
Having used RMAN/NetBackup to do many restores, that statement seems incorrect to me.
One thing that I have seen is that if the tape has been vaulted, the media ID changes and
RMAN no longer knows the correct media to ask for.
When that happen, I have to supply a date range to our Backup Admin, and he requests
the right tapes to restore to the time period.
As re-cataloging NetBackup tapes back into the RMAN repository is nearly impossible,
I never expire anything from RMAN. That way when an old tape is put back into NBU,
RMAN still has the correct names to request.
I guess it is possible to re-catalog NBU tapes back into RMAN, it just isn't documented by Oracle.
Here's an undocumented CATALOG command you may find interesting:
