That almost sounds like a damaged object. It's been some time since we've
seen that but then again I don't think I remember V5R1 that well anymore
anyway.
First clear QRPLOBJ library. It might have junk in it and you don't want
that stuff anyway.
Try running DSPOBJ *ALL/*ALL to an outfile
Query that out file looking for the damaged object flag turned on.
See if that's where the save is failing.
Blind stab in the dark at this point.

I can understand a tape drive going bad. What puzzles the heck out of me is
why it fails at exactly the same place every night.
The hardware vendor found a replacement, which they are going to put in
today. It is used and no warranty that it will solve the problem, of
course.
We use the tape drive cleaning cartridge when the system tells us to (about
every 30 days). Back in the day the S/36 had a tape drive (6157). There
was no cleaning cartridge; one was instructed to clean it by using isopropyl
alcohol on a swab. I mention that because I was wondering if that
could/should be done on these tape drives.

This is almost always a sign that the tape drive is going bad. We've had
that with LTO 3 drives in our library. Tapes would start be declared as
bad. We would have them replace the drive and it would go away.
Occasionally we would INZTAP with a CLEAR(*YES) just to ensure it was good
after the drive replacement. I think I could count the number of tapes we
threw away as bad on one hand.
I can't tell you what tape drives are currently compatible with your system.
Sorry. No alternatives to recommend. And, if it's too new yet still
supported on V5R1 it may have needed a certain PTF level. I've heard that
PTF's can be a bit tough to order for V5R1.

First, full disclosure: Model 250 running V5R1.
We have a cartridge tape drive 7207 Model 122. The data files backup runs
unattended each night. Lately it is crashing and burning with media errors;
in fact, it has failed the last four [4] nights.
Tapes do go bad, but it seems unreasonable to me to have this many go bad so
quickly. In fact, some of the tapes, except for initialization, have never
been used before. Plus it always blows at exactly the same place. And we
have cleaned the tape drive after each failure.
Am I being illogical to think that it is the tape drive, rather than the
tapes, which is at fault? Is there any way to determine that?
I have been trying to get the company to upgrade the system for years
with,
obviously, no success. Any other options? I have been told that this
tape
drive is no longer available (maybe eBay but you get what you pay for
there). But are there any other backup alternatives for off-line storage?
Thanks.
