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.
