Environment

VMware NSX

Cause

The Compute Manager has not synced correctly for some time with NSX and fails to pull the needed information for the SDDC task to complete successfully.

Resolution

This is a condition that may occur in a VMware NSX environment.

Workaround

Note: If both Validation errors and SDDC Task failures are observed (Failed to Acquire Resource Locks, Unable to create transport node collection with profile) apply both options below:

Option 1:

The workaround involves resyncing the Compute manager within NSX.

Note:

The workaround involves re-registering even if it shows that its currently in sync with Compute manager within NSX.

 

Follow these steps in the NSX UI to resolve:

1. Go to System>Fabric>Compute Managers
2. Slect Compute Manager
3. Select Edit
4. Click Edit next to FQDN or IP Address
   
5. Input Admin user and Password
6. Click Save
7. Retry Task within the SDDC Manager

Option 2:

The workaround involves detaching and re-attaching the TNP.

1. Go to System>Fabric>Nodes
2. Select the cluster that show the status of "Validation Error".
3. Select Action>Detach Transport Node Profile.
4. After detaching the Transport Node Profile > Click Configure NSX
5. Select the TNP to attach to this cluster and Apply.

 

Additional Information

Similar issue: NSX will not prepare a host with message "Transport Node cannot be created or updated because host is not attached to every VDS specified in Transport Node profile."
