We're setting up a simple HyperV cluster, just 3 Nodes, and it occurred to me to give some thought to unattended shutdown during extended power failure.
If I understand the workings of the cluster correctly, simply having each host independently shutdown at 50% battery (or whatever) is not going to produce a graceful shutdown of the cluster itself.
Is there any common way to link the shutdown signal from the UPS software to the cluster shutdown command (and then subsequently shutdown the machine itself)?
