• Closed as program error.

Error description

• During reclamation or move data, the server reconstructs
  bitfiles. During this process there can be a situation where
  the server using "query stgpool" will incorrectly report the
  number of 'Moved Bytes' as a size that way exceeds the size of
  the storage pool being reclaimed or of the volume being moved.
  
  For example:
  
  query stgpool

  Notice Moved Bytes is 16,383 PB but in this case storage pool
  has capacity of 540,170 GB
  
  Level 2 diagnostics:
  A server trace with DFMOVE AFMOVE ASVOL   flags will show total
  bytes reducing until it would have hit a negative number
  and thus reports the huge number.
