I recently have encountered a controller failure on our D5800f.

I have shutdown the subsystem, removed the failed controller and restarted. So now we are running as as single controller subsystem. Subsystem health is reporting a warning as noted in the title. Why is it reporting a battery missing for battery 2 when there is only 1 battery in the configuration?

Is there a way to clear this warning from the enclosure?

Second and more importantly, is there a service to repair a failed controller or where can I get a replacement controller?
