  ****************************************************************
  * RECOMMENDATION: Apply corrective PTF when available.         *
  ****************************************************************
  The RESTORE SYSTEM UTILITY fails with message DSNU1637I
  because no FLASHCOPY is available. There was a space
  efficient flash copy(SEFC), but the RESTORE SYSTEM utility
  made a determination that it was not a valid copy because
  HSM sets a different flag for SEFCs to specify that the
  copy is good.
  

Problem conclusion

• RESTORE SYSTEM was changed to check the correct flag.
