Mellanox ConnectX-3 not showing both ports?

[iamspartacus]

I installed dual port ConnectX-3 NICs into two different Proxmox 7.1 servers and I'm only seeing a single port on each show up. These NICs were pulled from working Unraid (Slackware) servers where both NICs showed up fine and were functioning. I had previously configured these NICs to run in Ethernet mode on a WIndows system. Can anyone advise on how I can get both to show up inside Proxmox?

enp67s0 && enp67s0

enp2s0 && enp2s0d1

are the 2 ports on the interfaces. (I have same connect-x3 with same naming)

Oh really? I thought it was just showing a duplicate since the bus is identical and it only shows one of the interfaces as Ethernet. Is that how it looks for you as well?

That's how it looks for me. I have four connectx-3 MT27500 cards and they all only have a single pci bus address even though they have two ports. I believe the connectx-4 does have a separate pci bus address for each port on a dual port card.

Hi!

did you find any solution?

I'm using the same interface on proxmox 7.2 and I'm having the same problem.

 

[spirit]

my connect-x3 ports on proxmox 7.2 are :
enp65s0 && enp65s0d1

so, it should be somethin like enpXs0 && enpXs0d1
