Flooded network due HP Networking Switches & Windows NLB
Today I was onsite at a customer to bring a tiny VMware vSphere cluster to life (HP BladeSystem c7000 with 7 HP ProLiant BL460 Gen8). Normally no big deal, but it started with two unavailable Onboard Administrator (OA) network interfaces. I switched from static ip addresses to DHCP, but I had no luck. I noticed that both interfaces were available if I connect my notebook directly to the interfaces. I even noticed that the Insight Display was unresponsive after connecting one or both OA to the network.
