Had supported the VXRail support team. Got the feedback, this is not supported in this version.
HI, I am having an environment with 3-Node E560F VXRail. There are 2 virtual Domain Controllers in this environment which is residing within this VXRail Cluster. I need to make sure that while bringing up the VXRail Environment, after a Poweroff, the Domain Controller VM's should be booting first. I have checked the VM Startup/Shutdown. But i cannot change anything, when i try using "administrator[NAME]" account. VXRail Version is 4.7.300 Any suggestions, most welcome.
