Setting up two new filers, F810 and FAS940, in a new installation. ONTAP 6.4.1

1. Is there a way that I can permit certain users to view filer configurations and statistics without their having the root password or being given full adminstrative access? 2. Is there a way to force logons to the filer (be it console, SSL enabled FilerView) to use Windows groups rather than having to hand out the root password? 3. Is there a way to allow certain people to perform manual snapshots without their being given full admin access? Something akin to a Backup Operator. 4. Along the same lines of 3 above is it possible to permit those same people to restore snapshots on particular volumes without their being able to access other volumes?
