Yes and No.
Yes you can use RMAN to Disk and then use any utility (NetBackup without the Oracle module, or TAR or CPIO)
to copy that backup to tape.
No, you cannot make RMAN "aware" of the tape backups. Thus, RMAN cannot restore directly from tape as it
does not know which tape has which backup set. You will have to use your NetBackup catalog or a manual / scripted catalog (if you use, eg. TAR or CPIO) to restore the files from tape to disk (the backup destination location
or any other directory) and, _then_ use RMAN to restore from that disk location to the database datafiles location.
