Shawn,
not too long ago we had a situation where multiple tapes were failing in
reading and writing, at first we suspected the drives so we let a
technician come over, he checked the drives but could not find anything
wrong with them. The problems with the tapes held on, even worse, more
tapes started to fail operations. Before TSM operations would be totally
disrupted we ended up ditching about 15 failing DLT tapes, this is after
more than a years worth of "heavy duty" use (collacated tapes and
in-library copy volumes).
The problem tapes were replaced and till date (4 months later) no
tape errors.
regards Walter Ridderhof.

I had a similar problem a while back on our ATL P3000. They ended up
replacing the drives because of a defect at the time in manufacturing. This
was on robots purchased around Sept/Oct of 1999. It was to do with pins
inside of the drives.
Often times, I hear "you have bad tapes" - if I were you, I wouldn't fall
for that. Have them send someone else out to look at it. As many times I
was told the same, but then when different eyes looked, they found problems.
For instance, one time, one of the fans were bad, but it was not indicating
it. This too led to some problems. Another time, it was one of the power
supplies was faulty and not always reporting a problem. In other words, ask
that they send another tech out.
In the two years of having two ATL robots, we had 1 tape go bad and that was
due to a drive that had went bad and killed the tape.

Hi
I have a ATL P3000 tape library that houses 330 tapes, the issue that has
just
arisen is that I have had to have service on all four of my DLT 7000 drives,
the
technician says that the tapes are no good, Does anyone have any ideas on
how to
manage the expiration of the tapes in the library, and how long should they
stay
in production.
Any help would be appreciated.
Thanks
