Thanks for your response.
When you said "shutdown and disable one of the RAC primary's", do you mean
1) shutdown the instance followed by 2) disable the instance and then 3) shutdown the server?
Are the following the correct steps when I'm switching back to the 2- node primary RAC?
1) Leaving one of the RAC nodes down, perform the switchover 2) startup the server 3) enable the instance 4) startup the instance
