FYI.....
   For those who use the TSM client snapdiff functionality to backup
their CIFS shares on a NetApp filer, I have been advised of the
following which affects those who upgrade their NetApp to the latest O/S
- OnTap 7.3.3:

   If you have any customers using the snapdiff functionality to backup
CIFS/NFS shares via the Tivoli Storage Manager (TSM) client please be
advised that when upgrading to ONTAP 7.3.3 the TSM client will cause an
abort with the backup operation complaining about an invalid ONTAP
version. This is not a particular ONTAP version that TSM is complaining
about, it is the fact that the API element has been enhanced with the
FileAccessProtocol. The work-around for this is to have the customer
place an entry ( TESTFLAG SNAPDIFFONTAPFAP ) into the dsm.opt file that
resides on the host. This option will bypass the check that looks for
the enhanced API that supports Unicode. This will be addressed in a
later TSM client version but is needed today for customers moving to
ONTAP 7.3.3.
