Error description

  • Issuing the MOVE DATA command against a volume in an active data
    storage pool may result in the following error, even though the
    active data storage pool is not deduplicated:
    
       ANR4895E Deduplicated bitfile 123456789 on volume
       /vols/00000001.BFS has invalid links.
    
    The problem occurs because the MOVE DATA operation attempts to
    copy an inactive grouped object, instead of skipping this object
    as expected.  Because the object has a length of 0, the server
    believes that the object is deduplicated which results in the
    ANR4895E error.  The ANR4895E error can be ignored in the sense
    that there is no problem with the actual data, however, the MOVE
    DATA operation will fail as a result of this error.  This
    problem will only be seen when issuing the MOVE DATA command to
    move data between volumes in the same storage pool.
    
    Platforms Affected:
    All V6 and V7 server versions
    
    Initial Impact:
    Low
