ORA-19565: BACKUP_TAPE_IO_SLAVES not enabled when duplexing to sequential devices

What triggered the Error:

attempt was made to specify duplexing to sequential devices, but the BACKUP_TAPE_IO_SLAVES initialization parameter was not enabled.

What should we do to fix it:

ecify BACKUP_TAPE_IO_SLAVES=TRUE in the INIT.ORA file, or do not specify duplexing to sequential devices.
