We upgraded our array from 1.4.9 to 2.2.5 yesterday. This morning our NOC opened an incident ticket about the heartbeat leds flashing amber. They insist they used to be a solid LED. I can't find anything in the change documents that references the LEDs at all, and as far as I can tell there isn't anything wrong with the array. For their sanity can anyone confirm they are indeed supposed to be flashing.
