[SOLVED] Unraid refuses to boot after moving to new motherboard

[phoenixcoder]

I tried to upgrade my unraid server by replacing the motherboard.

 

Replugged all the hard disks and moved the USB key to the new motherboard.

 

It gets hung on this screen

 

 

 

So I tried the advice here to take a backup of the /config, flash the USB then copy the /config back but it got hung on the same screen.

 

Thinking it is a hardware issue, I reflashed the USB using the USB maker and did NOT copy the /config directory, this time it booted up fine and got a login prompt so the hardware and unraid are compatible so far

 

However, after unplugging it, copying the /config again, then attempting to boot, it got hung at the screen above again

 

Any assistance will be appreciated

 

Thanks

Found the problem when unraid would boot without the sata cables from the SAS backplate.

 

Turns out, I had to activate the SAS controller on the motherboard
