Environment

VMware vSphere ESXi

VMware NSX-T 3.x

VMware NSX 4.x

Cause

This is an expected error in this configuration. Please see the Resolution field below for steps to properly remove an ESXi host transport node from NSX when it is part of a vLCM-enabled cluster with a Transport Node Profile attached in NSX. 

Resolution

1. In vCenter Server, put the ESXi host that needs to be removed from NSX into maintenance mode.
2. Move the ESXi host from the vLCM-enabled cluster to DataCenter object in the vCenter inventory. This will trigger the un-install of NSX from the ESXi host.
3. Check in the NSX UI if the ESXi host goes into 'Not Configured' state.
4. If any validation error is shown, click on the ESXi host in the NSX UI, then delete the host and select the 'force delete' option.
