You can uninstall NSX-T Data Center from a standalone host. Standalone hosts can be ESXi or KVM.

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

If you are uninstalling NSX-T Data Center from a standalone ESXi host, verify the following settings:
  • 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 None: Standalone Hosts.
  4. Select the host and click Delete. In the confirmation dialog box that is displayed, make sure Uninstall NSX Components is selected, and Force Delete is deselected. Click Delete.

    The NSX-T Data Center software is removed from the host. It might take up to 5 minutes for all NSX-T Data Center software to be removed.

  5. If the uninstall fails, select the host and click Delete again. In the confirmation dialog box, deselect Uninstall NSX Components and select Force Delete.
    The host transport node is deleted from the management plane, but the host might still have NSX-T Data Center software installed.
  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 the appropriate command to check for NSX-T Data Center software packages.
      Table 1. Package List Commands

      If the NSX-T Data Center software is successfully removed, no packages are listed. If any NSX software packages remain on the host, contact VMware Support.
