unable to remove NSX from ESXi on NSX cluster

Products

• VMware NSX

Issue/Introduction

• Unable to remove NSX from ESXi host as "Remove NSX" option is greyed out
• Transport Node profile is attached to the Cluster
• Cluster is not managed by vLCM 

Environment

VMware NSX

Cause

Transport Node Profile is attached to the NSX cluster

Resolution

Detach the Transport Node Profile from the Cluster:

1. Navigate to System > Fabric > Profiles > Host Transport Node Profiles in the NSX-T Manager UI.
   
   
2. Select the relevant Host Transport Node Profile.
   
   
3. Detach the profile from the cluster to which it is associated. This action will prevent newly added hosts from automatically becoming transport nodes; however, it will not affect existing transport nodes. 
    

Remove NSX from the Individual Node:

1. Go to System > Fabric > Nodes > Host Transport Nodes in the NSX-T Manager UI.
   
   
2. Select the specific host you want to remove.
   
   
3. If the Transport Node Profile is not attached to the cluster, you'll see the "Remove NSX" option.
   
   
4. Click "Remove NSX" and confirm the action.
   
   
5. This will remove the NSX configuration from the host.
