[SOLVED] Determining PCIe Devices

[AceBearpaws]

So I have a new installation of Proxmox. The motherboard in question has 3 sata devices. I suspect that this is because it has 8 sata ports that are standard, and then two ports that require a SAS breakout cable to function. My hope is that each PCI device corresponds to one of these port sets. 1 for the 8 standard satas, and 1 each for the two SAS ports. The problem is they all have the same exact label. Is there anyway to tell which is which for Passthru purposes so I don't accidentally pass through the ports that are being used as the Proxmox OS Drive?

Hi, if I understood you correctly this would be what you are looking for:
https://unix.stackexchange.com/ques...controller-and-scsi-address-of-attached-disks
lspci shows you the names of your PCI devices as well as their PCI address and sudo udevadm info -q all -n /dev/sda | grep DEVPATH should show you the device path with the PCI address. You can then cross-reference those.

This worked perfectly.

Thank you!
