Hello,   First thing is make sure that both controllers are cabled up.  In the GUI, when you select the member, under the "Controllers" tab do you see both controllers?   Do they show running the same firmware?   You might need to get the serial cable and directly connect to that CM to see what the failure actually is.  It could be a defective compaq flash card Regards, Don
I have a PS4000E that I recently upgraded the firmware to 8.1.3. During the upgrade and subsequent reboot, the member would not come online and join the group. However, when we reboot it again, it will. Currently, it is running on controller 0, and all is well. As a test, I initiated a restart, failing it over to controller 1, and again, it will not rejoin the group. I can ping the members management IP, I can even SSH into it in order to restart it again, back to controller 0. But it will not join the group from controller 1. I'd really like to resolve this. This has been a very reliable system, but I'm now in a position to have to schedule downtime for the next firmware upgrade because the failover isn't working as it should. My warranty is expired on this array, so I cannot just submit a ticket either. Suggestions?
PS4000E with possible failed controller?
