esx6 not identifying some nics

Hi there

Im having an issue with vmware identifiing and using some NICs.

The server is a dell 620 it has 4 onboard nic porta and three duel port add in nics

the onboard is an intel x520/i350

onboard

port 1 10gb  Connected

port 2 10gb  Conencted

port 3 1gb   Connected

port 4 1gb   Connected

1st nic x540t

port 1 10gb  Connected

port 2 10gb  Connected

2nd nic  x520

port 1 10gb  Connected

port 2 10gb

3rd nic  x520

port 1 10gb

port 2 10gb

This is how it looks on the idrac, below is how it looks in vmware

onboard

port 1 10gb  Connected

port 2 10gb  Conencted

port 3 1gb   Connected

port 4 1gb   onnected

1st nic x540t

port 1 10gb  connected

port 2 10gb  Connected

3rd nic  x520

port 1 10gb

port 2 10gb

If i move the sfp from card2 to a server or fluke tester the link comes up, if i move it to a port on the third card it does not show the module as inserted in vmware.

I dont see why that should be happening or why nic 2 is not showing up in vmware.

The cards are all intel and I think they are on the supported list, it was reinstalled with vsphere 6up2 dell edition, they all didnt show up with earlier vmware versions either.

If it were driver i would expect none of the x520 to work rather than one card not showing up.

I suspect that either the system has run out of interrupts. You can check on boot.gz file to identify if there had been any failure messages while allocating interrupts for the card.

Second possible reason which I faced sometime back was the populating done on the server itself. The powersupply requires both the populated sockets with equal number of PCI cards and the SFB cards were in particular more demanding
