You can uninstall NSX-T Data Center from a single host that is managed by vCenter Server. The other hosts in the cluster are not affected.

Caution: Uninstalling NSX-T Data Center from an ESXi host is disruptive if the physical interfaces or VMkernel interfaces are connected to N-VDS. If the host or cluster is participating in other applications such as vSAN, those applications might be affected by the uninstall.

Prerequisites

  • Verify that the hosts you want to uninstall have network uninstall mappings configured. See Verify Host Network Mappings for Uninstall.

  • Verify that the hosts you want to uninstall are in maintenance mode in vSphere.

Procedure

  1. From a browser, log in with admin privileges to an NSX Manager at https://<nsx-manager-ip-address>.
  2. Select System > Fabric > Nodes > Host Transport Nodes.
  3. From the Managed by drop-down menu, select the vCenter Server.
  4. If the cluster has a transport node profile applied, select the cluster, and click Actions > Detach TN Profile.
    If the cluster has a transport node profile applied, the NSX Configuration column for the cluster displays the profile name.
  5. Select the host and click Remove NSX.
  6. Verify that the NSX-T Data Center software is removed from the host.
    1. Log into the host's command-line interface as root.
    2. Run this command to check for NSX-T Data Center VIBs
      esxcli software vib list | grep -E 'nsx|vsipfwlib'
      If the NSX-T Data Center software is successfully removed, no VIBs are listed. If any NSX VIBs remain on the host, contact VMware Support.
  7. If the cluster had a Transport Node Profile applied, and you want to reapply it, select the cluster, click Configure NSX, and select the profile from the Select Deployment Profile drop-down menu.
