So do I get it right that you encounter this issue:


If yes try this steps:

-Connect to your SSR MS Database

-run the following query:
SELECT [_id]

  FROM [Symantec_CMDB].[dbo].[Inv_BESR_Volume]

-Look for the row(s) where GenericVolumeID has value of NULL

-Edit that row in the Inv_BESR_Volume table and enter the correct value in GenericVolumeID field e.g. C:\oder D:\ ist
