HP NIC Teaming, HyperV, NIC Teaming, NLB, Windows 2008 Server
This one has been definitely a adventure in getting up and running. In Part 1 of this I talked about what we had to do with the Teaming with HyperV. Well that wasn’t the end of the adventure as I thought. I had tested the VS Servers by pinging the IP’s which I would get a response from. I also tested browsing the network and Internet access all looked well. What happened though when I added a static IP to the NICs of the VS Servers was I could still ping the world but not go anywhere. I thought OK they work when DHCP handles the addressing so what I did was on the LAN NIC of the IIS Servers I set a reservation for the NIC and assigned the IP that way on the LAN NIC that we wanted and this worked. I could do what I needed to on the network and such so now what to do on the NLB NIC.
I started by googling the NLB setup of a Virtual Server and I came up with MS KB Article 953828. There was a hotfix for the 2008 Servers that would be doing this but nothing for 2003 Server. On this they talked of steps to do after the hotfix so I thought why not give this a shot. So I staticaly set the IP on the NLB NIC and then used the NLB Manager on Blade1 to configured the Load Balancing on the first IIS Server. Once this was done I shut down the IIS Server and on the NIC defined for the NLB in HyperV manager I added the MAC Address of the NLB Cluster IP started the VS Server up and it was working. I am assuming it has something to do with the switching of the Team and also the HyperV Switch and the MAC address of the involved NIC’s in the whole process. That is something to be figured out yet on why I seen this behavior but in the mean time I have things working the way they need to be working.
