We have a situation where a 2 node Hyper-V Cluster needs to be gracefully shutdown when primary utility power has been disconnected AND the UPS has less than 25% battery remaining.
The UPS’s that we are using (one Per Physical Host) is an APC SmartUPS 1500 that has USB only (no slot for smartnet card) and has PowerChute available to monitor the USB port (if that helps).
In the above configuration, obviously we cannot guarantee that both UPS units will last exactly the same amount of time. If UPS 1 reaches 25% battery first and begins shutdown then I assume the Hyper-V cluster node connected to it will try to transfer its guests over to the other node. However, should that other node begin shutdown in the middle of transfer because UPS 2 reaches 25% battery, will the guests be properly shut down or will they just be cut off? We expect to receive notification that transfer of virtual machines failed. That's fine. Our goal is to have the guests properly shut down rather than just cut off. Is that possible in this scenario?
