Environment

VMware Cloud Director

VMware vCenter Server

Cause

This issue occurs when the datastore containing the files is missing in vCenter Server.

 

Resolution

To check which datastore is being referred in the Database, take SSH to the primary VCD cell as root user. 

  • Connect to the VCD Database: sudo -i -u postgres psql vcloud
  • Execute the select query and note down the dstore_moref value from the output. 
    select * from managed_media where media_name='<File_name>';

     

  • Open the vCenter URL https://<vCenter_FQDN>/mob/?moid=<dstore_moref> in your browser and verify if the specified datastore is valid. If you encounter an "HTTP ERROR 404," it indicates that the underlying vCenter no longer has access to the datastore.
If the datastore containing the ISO/media files is decommissioned in vCenter Server, the files must be re-uploaded to the catalog in VCD before any required operations can be performed.
