Hello everyone. We are in the process of updating the RAID controller firmware on our hosts due to an issue the current firmware that doesn't seem to be playing nice with ESXi 5.1U2. (See THIS
We move all of the VMs and templates from the host and then put it in maintenance mode. we turn off the host and update the firmware. Then what we did with a couple hosts is remove it from vCenter and then reinstall esxi (we want to make sure everything is fresh). We then add the host back to the cluster and apply a host profile that we took before shutting it down and reinstalling.
My 2 questions are:
1. When attaching and applying the host profile to the host it says its not compliant. Even though we copied it from the same host before uninstalling. Everything looks to be working but im not sure if im messing anything up by keeping it in a non compliant state.
2. I was thinking, instead of removing the host from the cluster i will just do the above and then reconnect it to the cluster. but im not sure if that will cause any problems. I'm pretty sure it will prompt me to accept the key again when re-adding but would anything else be messed up by doing it this way?
