You can uninstall NSX-T Data Center from a physical server host.

Procedure

  1. From a browser, log in with admin privileges to an NSX Manager at https://<nsx-manager-ip-address>.
  2. Navigate the UI based on the NSX-T Data Center version and select a host:
    • (NSX-T Data Center 3.2.2 or later) System > Fabric > Hosts and select the Cluster tab.

    • (NSX-T Data Center 3.2.1 or earlier) System > Fabric > Nodes > Host Transport Nodes

      and from the Managed by dropdown menu, select None: Standalone Hosts.

  3. Select the host and click Delete.
  4. On the Delete Transport Node popup window, click Delete.
  5. If the host goes into a failed state and NSX-T Data Center VIBs cannot be removed, then run the del nsx command to remove NSX-T Data Center from the host.
    1. Before running the del nsx command, power off all tenant VMs running on the physical server host.
    2. On the physical server host, log in to the console. At the CLI terminal, run nsxcli.
    3. Enter del nsx.
      Important: Do not run nsxcli -c del nsx as a single command on the physical server host.
    4. Read the warning message. Enter Yes if you want to go ahead with NSX-T Data Center uninstallation.
      Are you sure you want to remove NSX on this host? (yes/no)
    5. Verify NSX-T Data Center VIBs are deleted on the physical server host by running the following command.
      • (RHEL/SLES/CentOS host) Run rpm - qa | grep nsx.
      • (Ubuntu host) Run dpkg -l | grep nsx.
      If the NSX-T Data Center VIBs are deleted on the host, the CLI terminal displays success message.
    6. To debug errors after running the del nsx command, see logs at /var/log/nsxcli.log on the host.
  6. In NSX Manager, navigate to the physical server host, and click Delete.
  7. In the popup window, select Force Delete and begin uninstallation.
  8. Verify the Configuration Status of the host is Not Configured state. This state indicates that NSX-T Data Center is completely removed from the host.

Results

After running del nsx, all existing host switches are removed, and the host transport node is un-prepared. If any NSX-T Data Center VIBs remain on the host, contact VMware support.
