Add the VxRail Hosts to the Cluster in VMware Cloud Foundation

Once the hosts have been added to the VxRail cluster, you can add them to the cluster in VMware Cloud Foundation.
If the vSphere cluster hosts an NSX-T Edge cluster, you can only add new hosts with the same management, uplink, host TEP, and Edge TEP networks (L2 uniform) as the existing hosts.
If the cluster to which you are adding hosts uses a static IP pool for the Host Overlay Network TEPs, that pool must include enough IP addresses for the hosts you are adding. The number of IP addresses required depends on the number of pNICs on the ESXi hosts that are used for the vSphere Distributed Switch that handles host overlay networking. For example, a host with four pNICs that uses two pNICs for host overlay traffic requires two IP addresses in the static IP pool.
  1. In the navigation pane, click
    Inventory

    .
  6. Select the cluster expansion type.
    This option only appears if the vSphere cluster hosts an NSX-T Edge cluster.
    L2 Uniform
    Select if all hosts you are adding to the vSphere cluster have the same management, uplink, host TEP, and Edge TEP networks as the existing hosts in the vSphere cluster.
    L2 non-uniform and L3
    You cannot proceed if you any of the hosts you are adding to the vSphere cluster have different networks than the existing hosts in the vSphere cluster.
    does not support adding hosts to
    L2 non-uniform and L3
    vSphere clusters that host an NSX-T Edge cluster.
  7. On the
    Discovered Hosts
    page, enter the SSH password for the host and click
    Add
    .
  8. On the
    Thumbprint Verification
    page, click Confirm fingerprint icon to confirm the SSH thumbprints for the ESXi hosts.
  9. On the
    Validation
    page, wait until all of the inputs have been successfully validated.
    If validation is unsuccessful, you cannot proceed. Use the
    Back
