Hi Guys
I have recently created a 3 Node Hyper-V Cluster with 3 HP Hosts.
The Server version on all 3 servers is Server 2012R2.
The cluster ran perfectly until I started getting Mac conflicts and lost all communication to my hosts. SRIOV is enabled.
What I have picked up on is that my TEAM, vSwitch and one physical nic all share the same MAC. In most cases I have read up on there is a conflict of 2 duplicate Mac addresses. In my case the one server has a duplicate of 3. I have even tried to manually change the Mac address but to no avail.
I have also read up on checking drivers and so forth my drivers are the latest version according to HP and windows updates are up to date.
There is no real answer out there as to why I am conflicting and my entire cluster losing communication. The quick work around is to Disable the Nic that is conflicting and all comes up immediately.
Your assistance is much aapreciated.
Thanks
