  ****************************************************************
  Due to a new flag that was incorrectly set by default, users of
  FLASHCOPY with extent space efficient target devices were
  experiencing increased response time and occasional command
  reject I/O errors during FLASHCOPY ESTABLISH commands.  The
  flag should only have been set on the I/O to ESTABLISH the
  relationship in certain use cases.
  

Problem conclusion

• The flag which changed the behavior for extent space efficient
  targets was updated to no longer be set by default.  A new
  ALLOCATE operand was created for FLASHCOPY ESTABLISH to allow
  it to be set if needed for certain use cases.  In addition,
  the code which issues the HCP6431 messages was updated so they
  now have the proper E suffix when displayed.
  
  Publication Changes:
  
  CP Commands and Utilities Reference
  
  FLASHCOPY ESTABLISH is updated to describe the new ALLOCATE
  operand which causes extents to be pre-allocated for extent
  space efficient target devices.
