As you know from my previous post, I just added a new blade to my environment. But everything was not as clean as I desired. For some reason when I went to move a existing node from one vSphere Cluster to another, vCenter crashed. I thought it was the state in which I left the node, but alas it was not. So what would make vCenter Crash, VMware Update Manager stop showing up as a plugin, and other management tools suddenly stop working, when they worked fine before?
