Best practice for RAC planned downtime maintenance?

user569151Oct 31 2012 — edited Nov 3 2012

I have a 3 node RAC on Linux redhat. DB version is 11gr2.

I want to know the steps to perform each node OS patch upgrade.

I want to be sure I did right steps:
1). Node 1, stop crs and do the OS patch upgrade.
2). same steps for Node 2, 3.

Is this right?

Thank you for any help.
