Hi
I have a dev and test setup running 3 hosts with ESXi 5.5 and a vCenter appliance. On the cluster there is no HA active, but we do use DPM to power on/off our hosts.
However the business is not satisfied with the "speed of powering on" a host/resuming it from a "moon/standby status". Basically it's because vCenter is quite conservative in waiting to power on a host because it first wants to make sure the host is down. So when powering on a host it always says (although the host got shut down maybe like 8 hours ago): "waiting for host to power off before trying to power it on".
My question to you guys is: is there a parameter in the Advanced settings or wherever that I can change so that vCenter is a little bit snappier with booting/waking up a host?
I KNOW that it's a default setting and it's something determined as "safe" by VMware and VMware wants to make sure no unwanted actions are executed, but I have tested this for my setup thoroughly and I take full responsibility in lowering this time out...
