• Resolution in KB Removing domain in SDDC Manager fails with error_message=Cannot delete a transport node which is part of TNP applied compute collection cannot be applied as other hosts in cluster using the TNP

Cause

The removing host workflow cannot remove the transport nodes because it fails to remove the Transport Node Profile from the host.

Resolution

1. Login to vSphere Client and locate the host to be removed.
2. Ensure host is in Maintenance Mode.
3. Manually take the host out of the vSphere Cluster (This will detach the host from the TNP applied to the cluster)
4. Login to NSX UI and navigate to System > Fabric > Nodes and Ensure Host is out the Cluster and is in Standalone host.
5. Select the host and click "Remove NSX"
6. Restart the Remove host task in SDDC Manager UI.
