Add new host to existing VXLAN cluster

Hello Everyone,

I have a cluster containing 2 hosts that are prepared to use VXLAN. Now I want to add new hosts to the cluster but I don't know how the preparation steps because the cluster are already configured (with 2 hosts). When I add the new hosts, the vmknic is not created.

My question is, how to properly add the new hosts to existing vxlan cluster?

Best regards,

ilmi

My solution to this "problem" is the following:

  1. Create a "dummy" vSphere Cluster in vCenter
  2. Add your new ESXi Host to this "dummy" cluster
  3. Make sure that your new ESXi Host is a member of the same dvSwitch, as the other "VXLAN" ESXi Hosts
  4. In vCNS Manager do a preparation of this "dummy" cluster, with the same settings as the original cluster
  5. Give the newly created "vmk Virtual Adapter" on the new ESXi Host a static IP, if needed
  6. In vCenter, put the new ESXi Host in Maintenance Mode and move it to the original "VXLAN" cluster
  7. Take the new ESXi Host out of Maintenance Mode
  8. Delete the "dummy" vSphere Cluster in vCenter
  9. In vCNS Manager, do a refresh in the upper left corner of the vCNS Manager window
  10. In the Preparation view, the "dummy" cluster should now be gone
  11. Test your Connectivity
    1. In the "Network Scope" view
    2. Click your Network Scope
    3. Select the "Clusters" pane, of the selected Network Scope
    4. Select one of your ESXi Hosts, and click the "Gear" icon, to test connectivity

I had the same issue. Normally vShield should start the prepare process automatically once you add hosts to a prepared cluster. But it seems that this doesn't always work. What helped in my case was rebooting the vShield Manager. After it came back online it detected the new hosts and started the prepare task right away.

Thought I leave this here for all the poor souls that still run a vShield instance.
