Environment

VMware Cloud Director 10.6.x

Cause

This occurs as the upgrade script tries to update the UUIDs using "tm_uuid_generate_v5" and fails due to a duplicate key in the "api_external_service" table. The ID in the error may not exist pre and post upgrade attempt as it tries to generate same UUID for multiple entries that has same name in the "api_external_service" table.

Resolution

The name in api_external_service table must be kept unique or clean up the legacy entry for the duplicate service. Please note: These changes cannot be applied to the system after the upgrade failure. The environment will require reversion to a healthy pre-upgrade state before proceeding.

It can be done by using API.

  1. GET /admin/extension/service/query (To get the above list of external services created)
    https://developer.broadcom.com/xapis/vmware-cloud-director-api/latest/doc/operations/GET-ServicesFromQuery.html
  2.  PUT /admin/extension/service/{id} (Alter the name to be unique)
    https://developer.broadcom.com/xapis/vmware-cloud-director-api/latest/doc/operations/PUT-Service.html
  3. Guide to API extensibility: 
    https://techdocs.broadcom.com/us/en/vmware-cis/cloud-director/vmware-cloud-director/10-6/-vcloud-api-programming-guide-for-service-providers-10-6/extending-vcloud-director-api/vcd-extension-services-api/register-an-extension-service-api.html
