Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• The sanity check is to validate the low level space map page
  boundary before extension of the new cluster. However, in this
  case there are mix of the information and cause the logic that
  was intended for insert also being triggered. The load phase
  of migration REORG acts like a normal insert to load data into
  the new LOB table space.  This is not expected by the space
  allocation. Therefore, the performance code was exercised to
  read just the last entry of the low level space map page,
  therefore, the sanity check is triggered.
