We have a active/passive cluster config. We had a power outage in our plant for about three minutes. The servers, external array, and network connections where all still up. The clustered servers and array are plugged into two ups's. Supposedly all the network connections where not lost. But all of our resources went offline. What could have gone down to cause everything to go offline if we had power to the servers, array and network connnections that were still up? Could it have anything to do with the DC. If the dc goes off the network what issues will that cause?
