Environment

VMware Cloud Foundation 3.x

 

Cause

An SDDC manager component may have been removed or uninstalled from the SDDC, leaving stale entries of that component in the SDDC manager database. 

Resolution

Contact GSS with a Support Request, to assist you in removing the stale entry from the SDDC manager Database.

Additional Information

Make sure that the IDs that are reported do not have any components associated in the SDDC manager inventory, and is only a stale present in the DB.
