After attending the VMware vSphere FastTrack course came back to play with the new power management features of vSphere. Using Jason Boche’s Post and attempting to set the Advanced configuration setting Power.CpuPolicy to static, received the following little error.

Did I have a typo? No.
Could not be rights as I am Administrator.
Did I have to set up Power Management in the Cluster? Checked, yes had already done that.
The next thing that I could think of is that it was linked to the hardware.

Shutdown the one of the ESX Hosts, went into the BIOS and set the Power Regulator for ProLiant to OS Control Mode. The default setting in my BIOS was HP Dynamic Power Savings Mode.

Restarted the server, once contactable in VC, was then able to change the setting to dynamic.

So moral of the story, make the hardware changes first, then do the VC changes.

Does DPM all work now? Not sure, still going through the rest of my cluster and testing…
