We have an issue with the AC suddenly dropping out in our compute closet. I've set the temperature thresholds in IPMI so that I can use the pre-configured "Host hardware temperature status" to trip when the room gets too hot. In the advanced actions I've tried using "enter maintenance mode", "enter stand-by" and "shutdown host" individually and together, yet the system still never gets to maintenance mode or shutdown. It appears to always be waiting for the guests to shutdown but never initiates any guest shutdown or suspend. This is 6.7u1, HA is off, and systems are set to automatically power down with the host. Any help please
