ghettohostshutdown vma 5 apc shutdown the cloud

Hi,

we have two rooms with esxi hosts running in one cluster.

if one room (or both) are in a power fault there are apc ups which have power for ~40minutes.

Till now we had vSphere 4.1 with the ghettohostshutdown an the pcns tool. Which worked fine.

But what in vSphere 5? With vma 5?

The goal is to shutdown all if one apc is running in the last minutes.

vMotion and HA are on!

Thanks!

Dirk
