Error description

• Starting in 7.1 the query process output has a new field call
  deduplicated bytes. This value represents the number of
  deduplicated bytes processed for the given process. Because the
  dedup info for an object remains associated with it even if it
  moves into a non dedup'd pool where it is actually no longer
  deduplicated this information is still seen by move data
  processing even when both the source and target pools are non
  dedup. A non zero deduplicated bytes value may be confusing to
  see in a case where no data deduplication actually exists. This
  value should be zeroed in the case were no actual dedup data is
  processed. For this situation to occur the data must have
  previously been in a deduplicated storage pool such that is has
  dedup info associated with it although it now resides in anon
  dedup pool.
  Below is an example of a tape to tape move data query process
  output that shows a value for deduplicated bytes:
  04 Move Data   Volume MA1078L4 (storage pool LTOPOOL), Target
                 Pool LTOPOOL, Moved Files: 162617, Moved Bytes:
                 63,187 MB, Deduplicated Bytes: 3,160 MB,
                 Unreadable Files: 0, Unreadable Bytes: 0 KB.
                 Current Physical File (bytes): 78,212 KB Current
                 input volume: MA1078L4. Current output volume(s)
                 MA1088L4.
  
  Tivoli Storage Manager Versions Affected:
  7.1 all platforms
  
  Initial Impact: Low
  Additional Keywords:
  TSM incorrect nonzero
  

Local fix

• Ignore any deduplicated bytes values for query process output
  not involved a dedup storage pool.
