OA49781: FRBACKUP SUCCESSFULLY WITHOUT FRTV AND FRSV RECORDS BUT FRRECOVER DSN FAILS WITH ARC1860I ARC1866 RC=18

APAR status

• Closed as returned (APAR cannot be resolved without additional info from IBM or customer.)

Error description

• FRBACKUP is successfull when FRTV and FRSV records are missing.
  There is no failure or warning during FRBACKUP COPYPOOL().
  It ends with RC=00
  
  But when user tries to recover a data set from such
  succesfull FRBACKUP it fails with:
  
  ARC1860I FOLLOWING 1 DS FAILED DURING FAST REPLICATION DS
           RECOVERY: DSNP.DSNDBC.ZA4325D0.RKA1TEST.I0001.A265,
           COPYPOOL=DSN$LOCDS0P$DB, DEVTYPE=DASD, VOLUME=WZP506,
           ARC1866, RC=18
  
  Description of ARC1866I explains RSN code:
  ARC1866I FAST REPLICATION RECOVERY HAS FAILED FOR DS
  RC=18 The backup copy does not exist.
  
  Details to the failure during FRRECOVER:
  ----------------------------------------
  Externally was tried:
  DB2 RECOVER TABLESPACE ZA4325D0.RKA14325 DSNUM 1
  
  PDA trace showed following DFDSS command:
  
  FRRECOV DSNAME(DSNP.DSNDBC.ZA4325D0.RKA1TEST.I0001.A265)
          TOKEN(X'C4E2D1D7D023F9905C3F8342D023F6626EAE')
          FROMCOPYPOOL(DSN$LOCDS0P$DB) REPLACE
  
  ARCFRDSM called ARCFRDSD
  
  ARCFRDSD gets "no record found" for READ FRSV, because
           FRSV for volume WZP506 doesn't exist.
  
  This is the reason for above ARC1860I failure message.
  
  This APAR should address:
  -------------------------
  - FRBACKUP needs to fail the backup or at least WARN the user.
  
  We still need to find why FRTV and FRSV were deleted.
  Therefore customer will run AUDIT COPYPOOL() daily:
  - If FRTV and FRSV are missing ERR177/180 will be indicated.
  - Customer will provide PDA from last day when ERROR occures.
  

Local fix

• To make the FRRECOVER possible you need to create FRTV/FRSV
  
  AUDIT COPYPOOL() shows in such case the missing records:
  ERR 177 I (FRTV) RECORD WAS EXPECTED FOR VOLUME volser AND WAS
            NOT FOUND
  ERR 180 J (FRSV) RECORD NOT FOUND FOR VOLUME volser, WHICH
            BELONGS TO COPY POOL cpname, VERSION vsn
  but it doesn't build them.
  
  You need to create Volume FRTV and FRSV entries using FIXCDS
  command.
  For example:
  Create the FRSV Source record WZP506
             FRTV Target record WZ#440
             in Copypool 'DSN$LOCDS0P$DB'
  
  1) FRTV Target record WZ#440
     Key is the target WZ#440, points to source WZP506:
     F DFHSM,FIXCDS I WZ#440 CREATE(X'00' X'E6E9D7F5F0F6')
  2) FRSV Source record WZP506
     Key is the source WZP506 points to CP 'DSN$LOCDS0P$DB'
     followed by x'0E' = CP len 14, num of versions 1,
     num of dump copies 0:
     F DFHSM,FIXCDS J WZP506 CREATE(X'00' X'C4E2D55BC2C3F4F15BC4C2
       40404040404040404040404040404040404040')
     F DFHSM,FIXCDS J WZP506 PATCH(X'1E' X'0E0100')
  
  Afterwards FRREOVER was possible for customer.

Temporary fix

Comments

• This APAR is closed RET. The documentation required to open a
  new APAR to pursue this problem:
  1 - PDA trace coverig the FRBACKUP which should have failed.
  2 - LIST COPYPOOL() ALLVOLS(ALLVERS) after the FRBACKUP.
  3 - PDA trace covering the FRRECOV failure.
  4 - Copy of the DFSMShsm Journal data set which should contain
      the delete of the FRSV record(s) in question.
