Termination comments: 
Intervention is half accomplished. Netapp documentation looks wrong and system-id change didnt succeed. A new case has being open to follow-up 2004193235. Still working on it. For the time being, no downtime for backup/recovery services, load is on the second node. Intervention is over. Looks like replacement NVRAM card was faulty. We re-set the old one. Both controllers are operational. No downtime for DB services.
