We have a 4 node Oracle RAC 11g R2 in vSphere 4. (I understand this being an Outdated version, we are working on upgrading it).
Meanwhile we are also addressing performance problem by making some tweaks but not much helpful.
Now the question been raised for a vSphere storage Multipath Policy change over from Fixed to Round Robin, but am worried about RAC stability post this change because of Voting Disks, your guidance in this case is much appreciated.
We are using HP EVA storage which is ALUA aware.
