We have 7.14 installed, and still get the error in the Event Logs and have raised this with NetApp which took a few weeks and came back with a Level 3 tech which said this is by design we cannot run chkdsk!
See quote below.
Like I said, Data ONTAP Hardware provider is only designed to take storage level snapshot. Data ONTAP Hardware provider is called by the VSS work flow, this only understand the VSS framework logic for backup and restore.
CHKDSK is a OS level workflow to check the NTFS consistency, not a backup operation.
To put it in the right way, it is by design and not a bug.
Let me know if there are any questions or concerns on this I will be more than happy to answer them for you.
