Issue/Introduction

  • When attempting to import a brownfield Workload Domain (specifically a 2-Node vSAN cluster configuration) into an existing VMware Cloud Foundation (VCF) 9.0 SDDC Manager, the operation fails.
  • The error displayed in the SDDC Manager UI / VCF Ops UI 
    Import operation for import with id c0ac####-####-####-####-########fc90 failed internally.

UnboundLocalError: cannot access local variable 'esxi_cluster_moid' where it is not associated with a value

Environment

  • VMware Cloud Foundation
  • VMware Cloud Foundation Operations

Cause

  • This issue is caused by the inventory placement of the vSAN Witness host within the vCenter Server being imported.
  • The VCF 9.0 brownfield import script (vcf_brownfield.py) fails to correctly parse the parent object ID (esxi_cluster_moid) when the vSAN Witness appliance is located inside a Folder in the vCenter inventory. The script expects the standalone witness host to be associated directly with the Datacenter or a Cluster context that allows it to resolve the Managed Object ID (MOID) correctly.

Resolution

To resolve this issue, the vSAN Witness host must be moved out of any folder structures in the vCenter inventory.

Steps to follow: 

  1. Log in to the vCenter Server intended for import.
  2. Navigate to the Hosts and Clusters view.
  3. Locate the vSAN Witness Host
  4. If the host is inside a generic folder, drag and drop the host so it resides directly under the Datacenter object.
  5. Ensure the Witness host is not nested within any other folder structures.
  6. Return to the VMware Cloud Foundation Operations.
  7. Restart the Workload Domain import workflow.
