I have an ESXi 5 host running 3 virtual servers. 1 of these servers uses a datastore via Software iSCSI on a separate piece of hardware.
When the two hardware servers (storage and host) experience an outage, the ESXi host is the first to boot up and fails to find the iSCSI datastore, which results in none of the virtual servers to starting. If I log into the vSphere client and rescan for datastores after both servers are up, it will find the datatore. Then I can manually start each virtual machine.
I'd like everything to boot up clean automatically when a power outage occurs. What am I missing?
As always, thanks for the help.

Before anything, please understand that you shouldn't be experiencing loss of power in this manner.
Do you have any ability to add some level of power protection to the environment? A basic UPS is the easiest way to deal with this...
I think you're focusing on the boot order rather than remediating the real problem; unstable power.
