  ****************************************************************
    After applying PM80707 / UK95633 in DB2 10, or
  PM93233 / UK98462 in DB2 11, two problems can be seen
  while running RESTORE SYSTEM utility with FROMDUMP.
  
  1. If HSM fails to return to DB2 normally when invoked by
  RESTORE SYSTEM with FROMDUMP, the RESTORE SYSTEM job
  fails with ABEND0C4 RC11 in DSNUVBRD near OFFSET1E7C
  (DB2 10) or near OFFSET11E4 (DB2 11).
    This was due to incomplete checking upon return from
  HSM to make sure all necessary fields were set correctly.
  
  2. RESTORE SYSTEM FROMDUMP can sometimes receive ABEND0C4
  RC4 in DSNUVBRD near OFFSET1E76 (DB2 10) or near OFFSET1242
  (DB2 11) shortly after HSM is successfully invoked.
    This occurred when DB2 accessed unallocated storage while
  copying a block of storage to a new location.  This problem
  is intermittent.

Problem conclusion

• The problems introduced by PM80707 and PM93233 have been fixed.
  1. an HSM failure received by DB2 during RESTORE SYSTEM FROMDUMP
  will now cause the job to receive
  DSNU1631I DSNUVBRD - RESTORE SYSTEM UTILITY FAILED BECAUSE
  THE CALL TO DFSMSHSM FAILED WITH RC = rc REASON = rsn
  and fail with RC8.
  2. RESTORE SYSTEM will no longer access storage which may not
  have been allocated.
