How to resolve: This operation is not permitted on a source that has never been opened by the Delphix Engine Last updated Save as PDF Background By default, when you enable a virtual database (VDB), the Delphix Engine attempts to start it, Problem If you have selected option to not "open database" upon provisioning and then try and enable the VDB it can fail with the error shown in the image below: Resolution Login to the CLI as 'delphix_admin@DOMAIN' user Go to 'source' Do an 'ls' to view all databases. Select the VDB you need to enable. Start a new 'enable' operation and edit the property of 'attemptStart' to false. Commit the changes. Example: kfc-4220.dcenter> source kfc-4220.dcenter > ls kfc-4220.dcenter source> select Vdb_notopen kfc-4220.dcenter source 'Vdb_notopen'> enable kfc-4220.dcenter source 'Vdb_notopen' enable *> set attemptStart=false kfc-4220.dcenter source 'Vdb_notopen' enable *> commit From this point you can use GUI to enable the VDB.
