If you have installed NSX-T Data Center on a vSphere Cluster using transport node profiles, you can follow these instructions to uninstall NSX-T Data Center from all hosts in the cluster.

For more information on transport node profiles, see Add a Transport Node Profile.
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.

If you have not used a transport node profile to install NSX-T Data Center, or if you want to remove NSX-T Data Center from a subset of the hosts in the cluster, see Uninstall NSX-T Data Center from a Host in a vSphere Cluster.

Note: Removing a host from a cluster does not uninstall NSX-T Data Center. Follow these instructions to uninstall NSX-T Data Center from a host in a cluster: Uninstall NSX-T Data Center from a Host in a vSphere Cluster.

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. Select the cluster you want to uninstall, and click Remove NSX.
  5. 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.
