Restarting VMs after a Datacenter Down Event
One of my customers recently had a catastrophic thermal event in one of their datacenters and so had to shut down all of their infrastructure at that site. After the cooling issue was resolved, we were asked to help them to get their infrastructure back online. Fortunately, we have included several small details as best practices in our vSphere designs, and one of those really paid off for us. We always create a VM to Host affinity rule that keeps one Domain Controller, the vCenter server, its PSC and its Database (if external) on a known host in the management cluster.
