Duplicate Database fails with RMAN-03009: failure of allocate command on ORA_AUX_SBT_TAPE_1

I want to use Database Duplicate to copy Database to another server. I am able to restore control file and mount the database but cannot trigger fur database restore.

On source Instance we used tdpo so I had to switch from tape to disk backup to be able to copy backup files to destination.

I ran following command to duplicate database:

RMAN> duplicate target database to orcl Backup location '/mnt/backup/oracle/sync';

I got following error afterwards:

database mounted

released channel: ORA_AUX_DISK_1

allocated channel: ORA_AUX_DISK_1

channel ORA_AUX_DISK_1: SID=393 device type=DISK

released channel: ORA_AUX_DISK_1
