PM82111: RECOVER FAILS TO RECOGNIZE HSM ERROR

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• Recover of an object using a system level back up failed with
  ABEND04E RC00D10307 and RC00E40106. There was a problem with the
  HSM restore of the data set:
  
  ARC1860I THE FOLLOWING 0001 DATA SET(S) FAILED DURING 951
  
  ARC1860I (CONT.) FAST REPLICATION DATA SET RECOVERY:
  ARC1860I (CONT.) hlq.DSNDBC.dbname.tsname.I0001.A001,
  COPYPOOL=cpname, DEVTYPE=TAPE, VOLUME=095030, ARC1866,
  RC=32
  ARC1802I FAST REPLICATION DATA SET RECOVERY HAS 953

  SET
  ARC1802I (CONT.) RC=0066
  
  DB2 ignored the MSGARC1860I and the RC0066 and attempted to
  continue the recovery.

  ****************************************************************
    User ran RECOVER utility on a non-partitioned object whose
  recovery base was a system level backup (SLB).  During HSM
  processing of the data set the following messages were issued:
  ARC1801I FAST REPLICATION DATA SET RECOVERY IS
  ARC1801I (CONT.) STARTING FOR DATA SET
  ARC1801I (CONT.) aaaa.DSNDBC.bbbbbbb.cccccccc.I0001.A001,
  ARC1801I (CONT.) AT hh:mm:ss ON yyyy/mm/dd
  ARC1860I THE FOLLOWING 0001 DATA SET(S) FAILED DURING
  ARC1860I (CONT.) FAST REPLICATION DATA SET RECOVERY:
  ARC1860I (CONT.) aaaa.DSNDBC.bbbbbbb.cccccccc.I0001.A001,
  COPYPOOL=DSN$PZ$DB, DEVTYPE=TAPE, VOLUME=nnnnnn, ARC1866, RC=32
  ARC1802I FAST REPLICATION DATA SET RECOVERY HAS
  ARC1802I (CONT.) COMPLETED FOR DATA SET
  ARC1802I (CONT.) aaaa.DSNDBC.bbbbbbb.cccccccc.I0001.A001,
  ARC1802I (CONT.) AT hh:mm:ss ON yyyy/mm/dd, FUNCTION RC=0008,
  ARC1802I (CONT.) MAXIMUM DATA SET RC=0066
    This happened because the user specified that only SLBs on
  tape should be used for recovery (zparm
  RESTORE_RECOVER_FROMDUMP = Yes) but had made their SLB only
  on DASD.  This was unintentional but DB2 failed to detect it
  and the RECOVER job ultimately abended with
  ABEND04E RC00D10307 (log read failure due to invalid RBA values)
  and RC00C90070 (fast log apply failure due to internal error).
  These reason codes were not meaningful and in fact different
  and unpredictable errors could have been seen.
  

Problem conclusion

• Code was changed in RECOVER utility to properly handle an
  error which is caused by the absence of an SLB on tape when
  the user specified zparm RESTORE_RECOVER_FROMDUMP = YES and
  the recovery is of an entire non-partitioned object.
    In this case
  msgDSNU1522I THE DFSMSHSM CALL TO RESTORE...FAILED WITH
               RC = X'hsm-rc' AND REASON CODE X'hsm-rsc'...
  will now be issued and RC8 set for the object.
