What I plan to script goes something like this:
(assumes collocation is in good shape - vols dedicated to individual

get list of nodes using the DD
for each node
  get list of vols (q nodedata <node> stgpool=<ddpool>)
  for each vol
    ssh to DD and get dedup info (filesys show compression <file>)

With some arithmetic I can get totals per node.
I'm thinking of a report with something like this . . .

 <node>  <node_occupancy> <num_vols> <dd_pre_dedup_size> <dd_dedup_size>
<dd_dedup_ratio> <date_time_stamp>

(the date stamp at then end allows grep'ing through multiple files to get
a history for a node in date order)
