I have Dell 2950s as my vSphere 4.0 hosts and they take forever to boot. I am using DPM to shutdown unused hosts and every once in a while one will fail. When I console into it, I see it is running fine, but vCenter says it failed coming back from standby. I'm thinking it is just timing out waiting so long. Is there any way to increase the timeout in vCenter to making it wait longer for the machine to boot?
