Environment

• VMware Cloud Director 10.6.0.x
• VMware Cloud Director 10.5.x
• VMware Cloud Director 10.4.x

Cause

This issue can occur if there are missing or incorrect "dstore_moref" values for the VM entry in the Cloud Director database.
For example if the entry is NULL or the VM entry in the database has the wrong datastore reference, i.e. VM resides on another datastore in vCenter.

Resolution

This issue has been fixed in Cloud Director 10.6.1, see Release Notes.

If not able to upgrade to the fixed version, to contact technical support and note this Knowledge Article ID (324408) in the problem description. For more information, see How to Submit a Support Request.
