I did the same thing, but I coded an SVC202 to an external REXX exec, makes it a lot simpler to test and maintain, and we can use CMS commands to tell VM:Tape to mount the next SCRATCH volume, update the job log, validate the tape (rewriting the header label if necessary), and position the tape past the SL with TAPE DVOL1 (LEAVE.
I'm surprised in ALL these years IBM hasn't provided a simple external exit for DDR. -Mike -----Original Message----- From: The IBM z/VM Operating System [mailto:ib...@listserv.uark.edu] On Behalf Of peter.w...@ttc.ca Sent: Wednesday, December 16, 2009 3:01 PM To: IBMVM@LISTSERV.UARK.EDU Subject: Re: Recommendation on Backup product for z/VM Hi David, Here's the mod to HCPDDR in all it's glory: ./ I 56317202 $ 56317702 500 11/28/07 15:19:06 * TORONTO TRANSIT COMMISSION MODIFICATIONS START HERE PART 1/2 * THE TWO STATEMENTS THAT PRECEDE THIS MODIFICATION ARE: * CKDEOV DS 0H * BAL R14,MSG005 GO PRINT THE END OF VOL MS TM DDRCMSF,DDRCMS RUNNING UNDER CMS?

Or if you plan to use any of the newer goodies in VM like the LDAP server or IMAP or some of the other nice things. IBM only supports use of SFS and/or BFS for these services, and if you think DDR sucks, wait until you meet FILEPOOL BACKUP. > Note that to use multiple > tape volumes for a disk volume backup with DDR and a tape manager, you > need to do a small mod to DDR so that it will call the tape manager to > mount the next scratch tape.

I think that should be a requirement (you can also use the pipe-friendly DDR stage that supports writing output to a pipe stage so you can just feed it directly into the TAPn stage and GET STANDARD LABELS (woo hoo)).
