We are in the process of migrating to a new IBM VTS System. We have some CA Dynam/T for z/VSE controlled POWER POFFLOAD Backup tapes which have to be copied to the new IBM VTS Library.
Can we use the CA Dynam/T for z/VSE program TDYNCOPY to do this ?
NO, because POWER POFFLOAD tapes have a special format.
There is a Tape Mark between EACH spool file, so TDYNCOPY cannot be used to copy these tapes.
We recommend using DITTO.
The following JCL EXAMPLE could be used:
// JOB DITTO // TLBL INPUT,'BACKUP.RDR.QUEUE',,,,,,8 "input tape with HOLD Option" // TLBL OUTPUT,'BACKUP.RDR.QUEUE.COPY',,,,,,8 "output tape with HOLD Option" // EXEC TDYNASN OPEN INPUT,SYS005,INPUT "AVR the tape and position after TM" OPEN OUTPUT,SYS006,OUTPUT "AVR the tape, write VOL1/HDR1/HDR2 TM" /* // UPSI 1 // EXEC DITTO $$DITTO TT INPUT=SYS005,OUTPUT=SYS006,NFILES=EOV "copy all the files on Tape" $$DITTO RUN INPUT=SYS005 $$DITTO RUN OUTPUT=SYS006 /* /* // EXEC TDYNASN CLOSE INPUT,SYS005,INPUT "update Dynam audit file" CLOSE OUTPUT,SYS005,OUTPUT "update Dynam audit file and Dynam catalog (CAICATL) /* /&
Ensure to test the resulting tape copy by doing a POFFLOAD restore before COPY a second tape.
