BTW, I've configured a multiple-NIC on both primary and secondary.
Both vNICs (on both primary and secondary) for public IP/mgmt IP and Channel IP use the same dvUplink (i.e., physical
network adapters).
BTW, I only have two physical network adapters on each ESXi host (one for vmk/mgmt console and one for vCSHB).
Would that make any difference?
