OA46089: AUDIT DSCTL(BACKUP) CAUSES *ERR 35 ERRORS FOR MCB RECORDS THAT HAVE BACKUP COPIES MADE WITH HBACKDS NEWNAME

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• If backup copies are made of a dataset using HBACKDS with the
  NEWNAME parm the MCB information for the backup copy will have
  MCBVER of '0000'.  Following this, if AUDIT DSCTL(BACKUP) is
  performed, *ERR 35 messages and FIXCDS commands are generated
  that attempt to set the MCBGEN value to '0001' regardless of the
  number of backup versions are present in the MCB.
  

Local fix

• Backup copies can still be recovered using GEN(x) or DATE/TIME
  parms.
  

Problem summary

• ****************************************************************
  * USERS AFFECTED: All DFSMShsm users of the AUDIT              *
  *                 DATASETCONTROLS(BACKUP) command.             *
  ****************************************************************
  * PROBLEM DESCRIPTION: The (H)BACKDS NEWNAME DATE command      *
  *                      will result in MCBGEN=0. Followed by    *
  *                      running the AUDIT DSCTL(BACKUP) command *
  *                      will result in ERR35 for the new backup *
  *                      version. ERR35 suggests the MCBGEN      *
  *                      field value, be modified to 1.          *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  AUDIT DSCTL(BACKUP) encounters MCBGEN=0 value then issues ERR35
  suggesting the MCBGEN value should be patched to 1.  Since
  (H)BACKDS NEWNAME DATE always results in the MCBGEN value being
  set to 0, it is incorrect for AUDIT DATASETCONTROLS(BACKUP) to
  change this value.  AUDIT DSCTL(BACKUP) should not issue the
  ERR35 when MCBGEN=0.
  

Problem conclusion

• Apply the PTF for this APAR to resolve this problem.
  
  z/OS DFSMShsm Storage Administration book, publication
  # SC23-6871-01  (applies to all V1R13 and later releases).
  
  Section - Optional parameters of the BACKDS command, at the end
  of the optional parameter NEWNAME, the final bullet under the
  'Note:' currently contains the following information;
  
  A backup version created with the (H)BACKDS NEWNAME will always
  have a VERSION NUMBER = 000.
  
  This should be changed to;
  A backup version created with the (H)BACKDS NEWNAME DATE will
  always have a VERSION NUMBER = 000.
