I do not!! That was a long time ago.
I found this under a Veritas thread:
have you tried re-registering the SQLVDI.dll...
- Stop all of the SQL Services.
- Search for, and document the location of each instance of sqlvdi.dll.
- Click Start, click Run, type Regsvr32 Path\SQLVDI.DLL in the Open box, and then click OK.
- Reboot the SQL Server.
Also, was SQL updated with any patches / HFs recently ?
Might be worth a try. There was a whole team of DBAs that we worked with and I don't have access to that email account at that company anymore or I'd try to find the email thread.
