The problem is not in Rman, bur in the software from the tapestation, it will register the IP or Node name the Rman backupset was generated and wh= en
Rman then try to restore the backupset from the other node it will fail. The way to fix this is to use a virtual IP / node when you backup and=20 restore
with Rman, the virtual node is normaly configered in a env varible or a=20 config
file for the backup software.
