Background / Problem

Just experienced an issue where an ESXi host was upgraded from 5.0 --> 5.1 perfectly fine.

Then, I did a scan and remediated a patch (ESXi510-201210401-BG) Looking into the host on via the kvm switch, this appears to complete successfully.

However, on reboot, the server hangs at the "Initializing Power Management" phase.

I've read from various spots around the internet that this usually clears itself up again upon a cold boot, but given that our servers are in a different building with different access rules, the less I have to physically go there, the better. :)

Question

• Is there anything I can do to avoid an ESXi host hanging at the "initialize power management" phase of boot after remediating the host to apply patches?
