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
