January 11, 20242 yr Hi, I have a problem with my dual NVME to USB3 chassis. It’s possible to install two NVME disks in the chassis. Then, each disk has it’s own USB connector. I’ve connected both to Unraid but unfortunately only one of them shows up on the START page for configuring the array. But in the System Devices section I can find both disks: USB Devices: Bus 002 Device 005 Port 2-1.4 ID 0bda:9210 Realtek Semiconductor Corp. RTL9210 M.2 NVME Adapter Bus 002 Device 006 Port 2-6.2 ID 0bda:9210 Realtek Semiconductor Corp. RTL9210 M.2 NVME Adapter SCSI Devices: [1:0:0:0] disk Realtek RTL9210 NVME 1.00 /dev/sdb 1.00TB [2:0:0:0] disk Realtek RTL9210 NVME 1.00 /dev/sdc 1.00TB Only the sdc disk shows up for the array configuration Do I miss something? Do I have to change some configuration? Thanks in advance EmEI6
January 11, 20242 yr Community Expert Solution It is a requirement of Unraid that each drive has a unique ID (typically serial number). It looks as if the USB3 chassis you are using does not pass through the serial numbers and has given both drives the same ID. The only fix to this is a different USB3 chassis that DOES have unique ID's for each drive.
January 11, 20242 yr Author Thank you for your comment. It is exactly as you said. The miserable implementation of the enclosure sets the serial number for both disks to 012345678904. That and the UID issue for licensing prevents it from working.
March 20, 20251 yr i think I bought the same usb enclosure you did. lol same issues, same numbers. Did you ever find another enclosure that let the drive s/n pass through?
