2008 R2 Failover cluster host network not added RRS feed

  • Question

  • I have a 2 node 2008 R2 Failover Cluster for Hyper-V. When I look at the list of networks in Failover cluster manager I only see my heartbeat and iSCSI networks. I have not idea why the local 'host' network isn't showing up. Both nodes are on the same subnet, and I even tried removing one node from the cluster (leaving only 1 node cluster) and the host network still does not show up in the list of networks.

    Is there something i'm missing? the only thing I have done recently is added the heartbeat network. in the past I was using the host network for this but that was not optimal.

  • Hi,

    the network detection within failover cluster is automatically done by NETFT (Topology Manager) which discovers your networks and adds 1 network per subnet to your cluster. Do you have used an different subnet for your new added HB network? normally the network will be added auto

    already validated your network?

    PS: just an reminder, in windows 2008 you normally don't need an dedicated HB nentwork anymore, just to have multiple networks on your cluster would be generally enough,.

  • Is your host network on the same subnet as your heartbeat or iSCSI network connections?
