This question keeps coming up...
Management classes are associated with individual file system objects, not 
nodes; and rebinding over time, as well as directory association rules, can 
make for a variety of MC utilizations for a single node.  Trying to report all 
utilizations is arduous, and not very useful.  It is better to sample key areas 
of the file systems, which can be done via 'dsmc query backup' from the client, 
or via -Virtualnodename from a comparable client.
