REASON: LAST VOLUME OF MULTI-VOL DSN NOT FOUND means that the DS1IND80 bit (last volume indicator) in the Format 1 DSCB is not on for the last volume of the Data Set.
This could be an indication for an invalid or corrupted Data Set and thus it is bypassed.
If this Data Set is considered a valid multi-volume Data Set, then the the DS1IND80 bit (last volume indicator) in the Format 1 DSCB can be turned on manually, running the DSCB Update Utility, to allow for the Data Set to be processed. Following a sample JCL and control statements to turn the DS1IND80 bit on:
//UPDATE EXEC PGM=ADSMI002,PARM=ADSDM235,REGION=1024K
//STEPLIB DD DISP=SHR,DSN=CA.DISK.CCUWLOAD
//ABNLDUMP DD DUMMY
//CMDPRINT DD SYSOUT=A
//MSGPRINT DD SYSOUT=A
//PARMLIB DD DISP=SHR,DSN=CA.DISK.CCUWPARM
//SYSPRINT DD SYSOUT=A
//SYSUDUMP DD SYSOUT=A
//SYSIN DD *
