I would be happy to be proven wrong on this, but I believe that snapdiff for 
CIFS is only supported on Windows.  snapdiff for NFS is supported on AIX and 
Linux.

BTW, that particular error message seems to be issued for a variety of reasons. 
 We have found it hard to figure out what the problem is at times, and we have 
an open PMR for this message right now.
