 We are considering using volume shadowing on our VAXcluster RA81 drives.
 Please comment on your experiences and general insights if you use
 volume shadowing at your site.


 Specific questions:
      What hardware / software versions
      How many volumes shadowed, types of drives, system, non-system
      Performance changes (+ or -) actually seen
      Volume backup procedures for system and non-system disks
      Problems

 Thanks,
