Another possible side-effect message, when Delphix disables the failed VDB is:

Disable dataset "examplevdb".
Error

Resolution

The problem occurs because the source database is a FILESTREAM configured database.  To check if this is the case, open the SQL Server Configuration Manager on your Source SQL Server Host.  Select the source instance and right click for the properties.

Here you see most filestream properties enabled.

The instance will allow one to create FILESTREAM databases syntax similar to the following, including an example of a table utilizing the feature capabilities:

CREATE DATABASE fstest
ON
PRIMARY ( NAME = fstest1,
    FILENAME = 'c:\data\fstestdata.mdf'),
FILEGROUP FileStreamGroup1 CONTAINS FILESTREAM( NAME = fstest3,
    FILENAME = 'c:\data\filestream1')
LOG ON  ( NAME = fstestlog1,
    FILENAME = 'c:\data\fstestlog1.ldf')
GO

-- table
CREATE TABLE fstest.dbo.Records
(
[Id] [uniqueidentifier] ROWGUIDCOL NOT NULL UNIQUE,
[SerialNumber] INTEGER UNIQUE,
[Chart] VARBINARY(MAX) FILESTREAM NULL
)
GO

-- inserts
INSERT INTO fstest.dbo.Records
    VALUES (newid (), 1, NULL);
GO

INSERT INTO fstest.dbo.Records
    VALUES (newid (), 2,
      CAST ('' as varbinary(max)));
GO

INSERT INTO fstest.dbo.Records
    VALUES (newid (), 3,
      CAST ('Seismic Data' as varbinary(max)));
GO

If a dSource exists for this database, then the feature is already enabled on the Staging SQL Server instance. Check the Target SQL Server Instance to ensure this feature is enabled, or you will receive the message when attempting to provision a VDB.

Once configured, a prompt will appear asking to restart the SQL Server instance.  If not prompted, one must restart the instance so the feature will be enabled for use.

 

Troubleshooting

Look for the this message in the error details you receive when the failure occurs:

FILESTREAM feature is disabled.

If this is present, chances are the FILESTREAM feature is not enabled on the instance.

Be forewarned: Databases not configured for FILESTREAM will provision on an instance running with FILESTREAM disabled.
