You can patch the OS in a rolling process as long as you're not changing the kernel version. This is sort of a grey area for Oracle, but we have done it a few times with 100% success.

Subject: OS Patches  

We've got a 4 node RAC 11gR1 on Linux 4.7 with ASM. We need to bring the latest patches into the OS and I was wondering what the best practice would be. I realize that we could do a rolling patch if we were patching CRS or the databases but can that be done for the OS? Would it be better (Safer?) to shutdown the whole RAC and do the OS patch to one node at a time or can we leave 3 nodes up while patching one?
