In an attempt to bullet-proof my system from Yet Another Mistake
Operators Make, I used TAPE WVOL1 to put standard labels on the seven
cartridges we use for nightly SPXTAPE dumps and changed how our DUMPNSS
SVM invokes our home-grown TMS so it now asks the TMS to verify the
label on the tape before the drive is attached to the SVM.
I also ran manual tests in which I did SPXTAPE dumps to each of the
seven tapes after labelling them, rewound them, and made sure that TAPE
DVOL1 still showed a tape label. It seemed to work as I expected.
Now I find that after a week of this, mounts of these seven volumes are
failing because there's not standard label on these tapes.
Is what I'm trying supposed to work?
Is there something I might be doing to cause SPXTAPE to disregard an
existing label and overwrite it?
z/VM 4.4, service level 0501, and 3590 B11s, if it matters.
Thanks,
Nick
