Issue/Introduction

After completing their HSM to CA Disk conversion, a LISTD report still showed 125 data set entries with Archive Key M00001.
These were the remaining CA Disk Conversion DSNINDEX records for MCDS entries that were created by CREATEFD, but not processed or failed by any HSMGEN1 job.
The customer reviewed these data set entries and found that they were obsolete and asked how to delete these entries.
 

How to delete obsolete DSNINDEX records with Archive Key M00001 or B00001 after completing a HSM to CA Disk Conversion?

Environment

Release:
Component: DISKOS

Resolution

The obsolete DSNINDEX records with Archive Key M00001 or B00001by can be deleted via the IXUPDATE utility. 
The delete statements can be generated by following sample JCL:

//*------------------------------------------------------------------
//DEL     EXEC PGM=IDCAMS
//SYSPRINT  DD SYSOUT=*
//SYSIN     DD *
  DELETE ABC.LISTD1.REPORT
  DELETE ABC.LISTD1.M00001.ENTRIES
  DELETE ABC.LISTD1.IXUPDATE.DEL.CMDS
//*-------------------------------------------------------------------
//STEP01  EXEC LISTD
//FILES     DD DISP=SHR,DSNAME=CAI.DISK.HSMMIG.FILES
//SYSPRINT  DD DSN=ABC.LISTD1.REPORT,
//             DISP=(NEW,CATLG),UNIT=SYSDA,
//             SPACE=(CYL,(5,1),RLSE),
//             DCB=(RECFM=FB,LRECL=133,BLKSIZE=0)
//SYSIN     DD *
  LISTD VOL=(B00001,M00001),
        FIELDS=(DSNAM,ARCDT,ATIME,FLAG1,VERS)
//*-------------------------------------------------------------------
//STEP02  EXEC PGM=SORT,REGION=5M
//SYSOUT    DD SYSOUT=*
//SORTIN    DD DISP=SHR,DSN=ABC.LISTD1.REPORT
//SORTOUT   DD DSN=ABC.LISTD1.M00001.ENTRIES,
//             DISP=(NEW,CATLG),UNIT=SYSDA,
//             SPACE=(CYL,(5,1),RLSE),
//             DCB=(RECFM=FB,LRECL=133,BLKSIZE=0)
//SYSIN     DD *
  SORT FIELDS=(2,44,CH,A,47,8,CH,D,56,4,CH,D)
  INCLUDE COND=(51,1,CH,EQ,C'.')
//*-------------------------------------------------------------------
//STEP03  EXEC PGM=SORT,REGION=5M
//SYSOUT    DD SYSOUT=*
//SORTIN    DD DISP=SHR,DSN=ABC.LISTD1.M00001.ENTRIES
//SORTOUT   DD DSN=ABC.LISTD1.IXUPDATE.DEL.CMDS,
//             DISP=(NEW,CATLG),UNIT=SYSDA,
//             SPACE=(CYL,(5,1),RLSE),
//             DCB=(RECFM=FB,LRECL=80,BLKSIZE=4000)
//SYSIN     DD *
  SORT FIELDS=COPY
*   BUILD THE IXUPDATE DELETE TIMEDATE=HHMMYYYYDDD,DSN=DSNAME COMMAND
  OUTREC FIELDS=(C' DEL TIM=',56,4,47,4,52,3,C',DSN=',2,44,80:X)
//*-------------------------------------------------------------------


Please modify the high level qualifier ABC as you need and run that attached sample JCL.   
The delete statements are generated by this job in STEP03 into the data set ABC.LISTD1.IXUPDATE.DEL.CMDS 

Then copy the delete statements (some at first) from ABC.LISTD1.IXUPDATE.DEL.CMDS and use them as SYSIN for following IXUPDATE: 

//STEP01  EXEC IXUPDATE  
//FILES     DD DISP=SHR,DSNAME=CAI.DISK.HSMMIG.FILES                   
//SYSIN     DD *                           
... 
/* 


After the IXUPDATE DELETE, you can double-check the result again with a LISTD VOL=(B00001,M00001). 
It should no longer show the obsolete entries.
