Thank you Diego, the problem was resolved by running the following commands on the Controller Shell:clearHardwareLockdownlemClearLockdownand then removing and reinserting the controller in a Failed state. After that, the controller copied the firmware and configuration from the working one and the storage went back to Optimal. 
Hi, I have an MD3200i with Dual controller. One of the controllers (1) Failed and went Offline automatically. Everything is working fine on the primary controller (0). I found a replacement controller, removed the failed one, and placed the "new" one in, but its still in the Failed (Offline) state. After that, I went ahead and reverted the change, now the Old controller does not get recognized. I'm currently with the replacement "new" controller installed but in a Failed (Offline) state.  My questions are: What is the correct procedure to replace the controller?  Now that I have the "new" controller in, do I have to place it online?  If I place it online would it pick up the config and the firmware from the other controller? Any help would be greatly appreciated.  Thank you!
