MLOM 10G SFP Card not showing on UCS C220 M5 port inventory

[jeffrey-garcia]

Hi - Need to find a suggestion on how to discover MLOM card for M5 server. We are trying to deploy Virtual APIC on this server and 2 physical ACI switches are connected to the MLOM card. The problem is we could not detect MLOM card on the server to select it as infrastructure card for ACI fabric.

I assume you've installed vSphere on the C220 M5.  If the mLOM is not detecting it's most likely a driver issue.  There's a custom image for vSphere that includes all Cisco UCS drivers required.  I would suggest installing this image on the server. 
vSphere 7: https://customerconnect.vmware.com/downloads/details?downloadGroup=OEM-ESXI70U3-CISCO&productId=974
vSphere 8: https://customerconnect.vmware.com/en/downloads/details?downloadGroup=OEM-ESXI80-CISCO&productId=1345 

Alternately, you can install the required drivers separately post regular install using the Driver iso for VMware ISO: https://software.cisco.com/download/home/286318809/type/283853158/release/4.3(3b)

A clean install using the Custom ISO would be the easiest solution.
Regards,

Robert

Hi Robert - Thank you. Sharing a screenshot of what we get on CIMC controller with regards to 1457-MLOM - status N/A - could this be the reason we cannot see the NIC on Esxi?

No, the inventory of the IMC has nothing to do with the OS drivers missing.  That's the likely reason you're not seeing the interfaces in ESX.  Resolved that first as detailed above.
