Sorry. I'm trying to restore a database - P00. The database currently runs on a three-node RAC with instances P0001, P0002 & P0003. For the restore, I've set up a RAC which consists of one node. The instance I'm trying to utilize on this node is P0001. Storage is ASM.

You're correct, the database is started in nomount mode. I can't seem to get it to register statically with the scan listener.

Here are the RMAN attempts, the listener.ora file, the endpoints_listener.ora file and the tnsnames.ora file.

RMAN> connect target sys/<password>_at_P0001
