While awaiting my MOS CSI access to be approved For Exadata HW issues so I can open an SR, I have a question. We are about to apply QFSDP for BP 22 on one of our full RACK X3 Exadta servers. Currently, the Grid Infrastructure (GI)/DB SW is at 220.127.116.11.0 and teh storage SW is at 18.104.22.168. Our last BP was 19. BEFORE we apply the BP 22, we want to upgrade the clusterware to 12c - but not the DB (that will come later). This is a high level question which I have discussed with several Oracle techs, but wanted to see what the experience/opinion is while I await access to my CSI. Can you have your Grid Infrastructure (GI) running at a higher version than that of your your storage server? The tech I spoke to said that all GI/DB SW should be at a version that is NO GREATER than that of the storage server - meaning a 12c version of the GI would not be compatible with a lowere version of the storage server. Thank you in advacne for any guidance.
