After any Hardware Change, HDD Storage doesnt show up

I am using a X570 ASUS TUF Gaming motherboard and installed the following storage parts:

1.) 500GB PNY NVME

2.) 4 TB HDD

3.) 4 TB HDD

4.) 1 TB Kingston NVME mounted through PCI 4x Card on the secon 16x Slot, because I dont have a exclusive 4x Slot

5.) 2GB USB Stick => UNRAID


The Storages show up in the BIOS, everything is recognized, but UNRAID found everything except my both 4 TB Storage, which stands for my actual array (1 Array, 1 Parity).

Is there someone who knows the reason why unraid can´t read both 4 TB hard disks? Maybe there are people facing the same issues? 😞


Thanks in advance.

SATA controller is bound to vfio-pci:

08:00.0 SATA controller [0106]: Advanced Micro Devices, Inc. [AMD] FCH SATA Controller [AHCI mode] [1022:7901] (rev 51)
    Subsystem: Advanced Micro Devices, Inc. [AMD] FCH SATA Controller [AHCI mode] [1022:7901]
    Kernel driver in use: vfio-pci
    Kernel modules: ahci


Unbind it.

thank you for your fast reply. You are absolutely right!!!

That makes sense, because only SATA connected devices are affected.

08.00.0 was my Nvidia 2060 GPU I have added to the vfio config. After the install of the PCI device on the second 16x slot seems to change the IOMMU numeric order of these devices, as the following screenshot shows:


Now my GPU has the number 09.00.0 (before 08.00.0). So I changed the config as you mentioned and now it works. Thank you so much for your help!!!!

Have a nice day! 

Best regards, Reini
