Hi
just to double check. you are mounting it from a snapshot created by SMSQL - not one that created by SV or browsing directly to the volume "active" file system, right?
i can't find a reason for you to see this message if the backup taken properly (search for it in the context of proper backup don't give much) and the VDI spec netapp use is suppose to freeze the IO so no in-flight transactions are expected https://technet.microsoft.com/en-us/library/cc966520.aspx
let's face it. if that all you have - you need to force mount whatever you have... (with that or these 3)
you anyway lost some data that appended after the backup. so if you manage to mount it you will have to handle the consistency issues (if exists) manually.
