Hi Shawn,
I'm dealing with the same (or look-a-like) issue on a Quantum i6k library with
LTO5 tape drives. The labeling of new LTO5 tapes fails with an Atape driver
higher than 12.3.7.0, TSM support analyzed the trace files and their analysis
is that TSM is trying to label the tapes first at high density which fails.
Then an attempt on low density fails too. With the 12.3.7.0 driver, only a low
density labeling is executed which succeeds. Besides the labeling, TSM cannot
longer use the LTO5 drives at all. So I've ended up downgrading the Atape
driver to 12.3.7.0 again. The TSM server 6.3.1 is running on AIX 7.1
I got both a PMR open at IBM and a SR at Quantum. Perhaps we should exchange
the numbers so we can make IBM and Quantum clear that multiple customers are
facing the same issue.
best regards,
Kurt

Onderwerp: Re: [ADSM-L] AIX Atape request
It is a setmode problem that resulted from an incompatibility between the
atape driver and firmware. I assumed it was the drive firmware, but now
I'm thinking it might have something to do with the library. It
apparently only happens in a Quantum i6000 with IBM LTO5 drives.
IBM says that it is a quantum problem, but quantum says it's IBM that
provides them with the firmware in the first place.
Here is an output from the trace:
16:35:38.737 [131][psntpop.c][2871][DetermineResult]:Error performing

to Appendix C in the 'Messages' manual for recommended action.~
I tried every atape version going backwards from the current 12.5.2 down,
and 12.3.7.0 is the newest version that does not have this bug. I also
tried every combination of drive firmware with each of these versions
going back to Jan 2011. All had this problem after mounting a tape.
12.3.7.0 didn't work for me, because there was a separate
encryption-related bug that was fixed with in 12.3.9!
I finally downgraded to 12.3.2.0 and everything is working now. This is
only a temporary environment so it won't affect me in the long-run.

Shawn

Hai Shawn,
Can u share what exactly the bug that caused the necessitates to downgrade
your Atape driver version?

Greetings all,
I ran into a bug which necessitates downgrading my Atape version. The
only older version I have is 12.3.7.0, which is subject to another bug
that is also affecting me. I need to get an Atape version between 12.3.9
and 12.4.8.0
IBM fix central does not have it and IBM support tells me Quantum will
have it since it is the result of their incompatibility or something.
Quantum only links to IBM. Google is not helping either.
Does someone have their own little archive history of Atape? If so,
please send me a copy or send me a link. I'm shocked that this stuff is
not available "out-there"
After this, I will definitely be maintaining my own archive.
Regards,
Shawn
