I am not really a VM person, so I am asking for help a bit .
Does anyone have a Rexx proc that will take a list of disks as input and back
them up to one tape . We just became the proud owners of 3590 drives. Before it
was at least two tapes per disk. (yes we took a few boxes of tapes to do
for example 2 rexx proc:
1. dfors exec
TRACE ALL
EXEC DFOR 133
EXEC DFOR 134
EXEC DFOR 135
EXEC DFOR 136
EXEC DFOR 139
EXEC DFOR 140
EXEC DFOR 12F
2. dfor exec
TRACE ALL
STACK SY CONS
STACK IN 1 3390
STACK OUT 181 3590 (LE CO
STACK DUMP ALL

I hate to nitpick (okay, I enjoy it actually) but that is in no way a rexx
proc. That's written in EXEC2, the language Rexx was designed to replace.

Hilary,
Here is what I use, for what it's worth. It get's the job done. I put in some
/*% ...' where you would make changes for your shop. It's not
perfect, in fact I have some more work to do to make it 'pretty' and more
error-catching. Unfortuately I don't have the restore exec.
A suggestion: In place of the DDR on the S disk, use CMSDDR
(downloadable from the VM Download library at www.vm.ibm.com/download),
and dump the volumes to a CMS file with a meaningful name (like vaddr
date). Then you can use TAPE DUMP or MOVEFILE to move the files to
tape (also gives you SL
This methodology can give you a scanable tape but it does increase your
i/o load and elapsed time quite a bit. If you have enough spare DASD,
you could do all of your production backups to DASD during your backup
window and then move the CMS files to tape after your backup window. But

It's manageable if you can put the scratch disk out of the line of
processing for production work (ie, different string or controller).

Thanks all of you.
And thanks to Shimon who called me and sent his version too :)
I actually have enough dasd to copy all my disks (45 3390 m3) that takes
about 2 hours of down time.
Then during working hours I can ddr those copied disks to tape.
The last time I did a drp exercise I had 90
