Daisy Chain Issues When Restarting Computer

I’m daisy chaining two G-Tech drives (Thunderbolt 3) with no problems. That is, until I restarted my computer just now. The drives are a 6TB G-Drive and a 20 TB G-Raid. The computer is a new 2020 Mac Pro. I’m having a hard time getting the computer to recognize these two drives and I am guessing there is a proper sequence for restarting the drives and hooking up the Thunderbolt 3 cords for daisy chaining. Any suggestions for getting the computer to recognize the drives?

I have the same problem and cannot get answers from the manufacturer or anyone else.
