  Utilities, COPY or Recovery, requested DB2 buffer manager to
  open page set of segmented table space like partitioned table
  space. Buffer Manager will turn on an internal flag to reflect
  the special treatment.
  During log apply phase of the Utility, data manager honored the
  internal flag and treated the classic segmented table space as
  universal table space. As the consequence, UNDO insert or REDO
  delete made a pseudo delete record on the page, and caused the
  inconsistency.
  

Problem conclusion

• DB2 code is modified to honor another flag which reflects the
  table space definition to detect whether the table space is
  partitioned or not, during utility log apply phase.
