We have a Fujitsu server with this specific RAID Controller (FUJITSU PRAID EP400i / EP420i). We want to export the configuration of that RAID Controller to a new one, so in case that RAID controller stops working, we replace the new one with the exact configuration from the previous one. From what I know, I need to find a way to access the index file and copy to another raid controller, does anyone here knows if it is possible and how? Greetings.
All Disks which are connected to the RAID controller have their own metadata of current configuration and in case of failed RAID controller it is enough to just replace it. The new RC will ask you to import existing configuration. Note: You need same firmware level on each raid controller.

*Scenario 1: Replacing a controller with the same model When you power the computer back on after the controller has been replaced, the RAID controller will automatically detect the RAID table information stored on the drive and will store the information within the NVRAM of the Adaptec RAID controller. At this point, you have successfully replaced the controller.*
