After I switched from Supermicro server to Cisco USC dual server Unraid does not show drives in Unassigned devices but they are shown in System devices. Don't know how to fix this & preserve data on the drives. Diagnostic file is attached.

Any help is appreciated.

You're using a RAID controller, those are not recommended, but if you want to use you might need to pass-through each device to the OS, some controllers require creating JBOD/RAID0 volume for each device.

Each drive is set to JBOD in server settings.

I can not change the RAID controller as its part of chassis unfortunately.

Looks like a firmware fault in the controller resulted in it killing itself off which then resulted in a ton of errors on each drive

Which ultimately led to the OS not being able to utilize the drives

Complete shot in the dark, but update / reflash the firmware on the controller.
