    ****************************************************************
    The RESTORE SYSTEM UTILITY fails with message DSNU1637I
    because no FLASHCOPY is available. There was a space
    efficient flashcopy, 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.
