We have a brand new 8.3 physical Appliance that I was trying to add as a Replica. It has failed and wants me to factory reset. The blue button at the bottom of the window is not working to reset. I need to know how to do it from the Linux Prompt or which ever way I can.
Since you have physical access to the appliance, I'd suggest downloading the iso of AM 8.3, burning it to a DVD and booting the appliance with the DVD to reinstall it. AFAIK, that's the official "factory reset" for 8.3
