  ****************************************************************
  During rollback of an ALTER TABLE ADD PARTITION, abends
  occurred processing a partitioned table.  The total number
  of partitions is less than the high partition range of an
  entry in an internal DBET control block.  During processing
  of the ALTER to add a new partition, the new partition is
  placed in extend-in-progress and the entry added to an
  internal DBET control block.  During rollback, this
  newly added entry is not cleaned up properly and is
  left in the control block.  Checks done later to
  ensure consistency fail when it finds this entry
  still in the control block.
  

Problem conclusion

• DBET has been modified to correctly clean up during rollback
  of an ALTER TABLE ADD PARTITION.
