Mike, would it be possibe to network connect the two systems, and avoid using
tape at all?

Thanks Alan, we can certainly give that a try.. But... I assumed (there is
that problem word) that if we mounted the tape cartridge, did a "TAPE REW"
then a "TAPE DUMP * * A" that it would wipe out any standard label on the
cartridge... that it would become a no-label tape no matter what it was
before...
As far as I know (!), he has no tape management software or anything else
that would be monitoring or looking for standard labels.
I will mention the SL issue to him though, just in case....
Thanks

A zVM 5.3 user (not even one of our customers) is trying to use a 3590
to
migrate from their current ( about to expire) FLEX-ES system to a system
z
and is having problems.
From zVM he can (apparently) write to the tape and do all the control
commands (rewind, unload, wtm, etc.). But he cannot read anything that
was
written by VM. If he does a DDR DUMP, he gets an I/O error on the DDR
RESTORE. If he does a VMFLPC2 or TAPE DUMP, the corresponding LOAD
fails
with a DMSP2C057E " Invalid Record Format". My best guess is that the
drive is writing in one mode (COMP/NOCOMP) and trying to read in the
other... but....
- I think that when reading, the drive should detect the mode used to
write
the tape and handle it either way
- We tried various combinations of MODE COMP/NOCOMP to try to force it
to
the right mode, with no apparent improvement.
I don't believe he has tried a stand-alone DDR, but I'm not optimistic
that
would be any better.
Any suggestions?
Has he used DDR, MOVEFILE, DITTO, PIPE, whatever to simply look at the
tape? Perhaps it has a standard label on it, something easily handled by
z/OS. If so, TAPE FSF to skip the label, then TAPE LOAD.
