Hello,
The PCIE link is the inner-communication link between the two controller which handles their heartbeat communication. Without a log review it is hard to tell if Controller A lost the heartbeat to Controller B and issued a kill to Controller B, or if COntroller B lost the heartbeat communication with Controller A and took itself down.
My suggestion is to gather a set of logs first and hold onto them in case you need them later. The controller that is down, try to issue a shutdown command through SSH. The command will likely fail but it is good to try and shut it down correctly first. Then remove the controller from the backplane about an inch. Wait for 5-10 minutes. This will allow failover to occur and the surviving controller to rescan the backend and perform other necessary steps. Check the controller that was removed and ensure all the LEDs have stopped flashing. Then insert the controller. It should boot up and resume normal operation.
There have been several fixes for PCIE link errors in newer firmware. Be sure you are running the latest firmware versions. You can check the firmware on your system here: www.hpe.com/storage/msafirmware
Also, if you wish to check other components on your array you can perform an MSA Health Check here:
