vNIC, vmnic naming mismatch in UCS and ESXi

I cannot get an ESXi host management network up in UCS B series blade. My friend has trouble kickstarting Linux on a different B series blade.

Check the vNIC ordering in UCS. The interface ordering in the OS usually match the vNIC ordering in UCS but not always. For instance it should be
vmnic0 = vNIC0
eth0 = vNIC0

Depending on how it was setup this is not always the case. Hence match the mac address in OS and UCS to verify. It saved my day.
