Ran into a wierd issue just now, server stopped responding, lost network connectivity (was only this server on the network that went down so i know it's the server), couldn't verify if console was frozen or not.
Went to the server room, and the RAID LEDs were green (which is normal) but they weren't blinking to show HDD activity, just constantly on and not blinking, i also heard a louder than usual "whir" noise from the server, lasted only a minute or two. The sound stopped and the RAID LEDs started blinking like normail again.
Everything working OK at the moment, event logs dont show anything abnormal on the server.
Anyone have any ideas on what this could have been?
