I have problem in need of a solution.
My Hyper-V Host (core) are all deployed with standard redundant power supplies and reduntant UPS
I can lose a Circuit/UPS/Power Supply and host (SHOULD) stay up..... BUT!!
Here is my problem. I want to use the graceful shutdown, meaning a usb cable from the ups to the server, coupled with software on the host, that will signal the host to perform a graceful shutdown after 30 mins on battery.
I don't see how I can get the host to communicate with BOTH ups, and NOT shutdown in the event 1 of the 2 ups loses power and has been on battery for more than 30 minutes?
If UPS A loses power, and the signal cable (usb to server) is connected to UPS A, the host IS going to shutdown, despite the fact its still getting power from UPS B? because that is where its reading/getting signal via cable/software combo.
