When you add a host from a VMware NSX enabled cluster, the NSX VIBs are automatically installed. The process steps for adding hosts to a VMware NSX enabled cluster is the same as if you were adding a host from a standard vSphere cluster.


This post assumes the following:

  • The target VMware ESXi host(s) are already connected to vCenter Server.
  • The target VMware ESxi host(s) are already connected to any relevant Distributed Switches.

Add a Host to a VMware NSX enabled Cluster

Note: These steps assume you are not even logged into vCenter Server. Skip the first few steps if you are!

Using your favourite web browser, navigate to the vCenter Server login page (https://vcenter.fqdn).

Enter appropriate User name and Password and click Login.

Double click on Hosts and Clusters.

Locate the target host.

Right-click on the host and select Maintenance Mode and Enter Maintenance Mode.

Click OK.

Drag and drop the target host into the existing NSX enabled cluster.

Right-Click on the target host and select Maintenance Mode > Exit Maintenance Mode.

Click Home > Networking and Security.

Click Installation.

Click Host Preparation.

As you will see, for my homelab environment, we now have two clusters, one is NSX enabled with two hosts and one has no hosts.

If no other configurations are required, logout.
