Dynam for VSE Dynam VSE Option

Issue/Introduction

You are in the process of migrating to a new IBM VTS System and 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 the CA Dynam/T for z/VSE program TDYNCOPY be used to do this ?

 

Resolution

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.

Additional Information

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.
