Len,
Thanks for your reply. No, we did not upgrade any of the TSM
software, including the tape drivers. We were running the
TIVsm-tsmscsi-6.1.3-1.x86_64 version both before and after the RedHat
5.2 to 5.4 upgrade.
I have since found out that there is a 6.1.3-3 version of the
driver. Since they are running the 6.1.3.3 version of TSM, they
probably should be running that version of the driver, too. I don't
know why or why not, since that is before they became my customer. The
previous TSM admins that set all this up are no longer working for this
company.
But I hesitate to recommend upgrading the drivers as a course of
action unless I can point to a concrete reason why. I went through the
Release Notes and Readmes and could not find any hint of a driver
problem being addressed. None of the tape driver APARs described since
6.1.3 in this Technote sound like they have anything to do with our
problem:

Any insight would be appreciated.

tape drivers
Greetings,
I have a customer running TSM 6.1.3.3 under RedHat Linux 5.2. The
Library Master instance on this server has a HP ESL722 tape library with
LTO4 tape drives, and a HP VTL emulating a ESL tape library with LTO3
drives. They are running the TSMscsi drivers to talk to the drives,
version TIVsm-tsmscsi-6.1.3-1.x86_64. Any time they reboot the server,
they execute:
cd /opt/tivoli/tsm/devices/bin
./autoconf -a
which loads the tsmscsi driver and configures the drives. This has been
working fine for months now. The output is:

Yesterday they tried to upgrade from RedHat 5.2 to 5.4. We didn't
change anything on the TSM software. The upgrade went fine, and after
the reboot onto the new kernel, they went through the same routine of
running "autoconf -a". This time when the TSM Library Master came up,
it got I/O errors on each of the drives, and was not able to mount
anything. It said it initialized the Library OK, but I have no way to
know if that was really true.
We were not able to figure out the why RedHat 5.4 caused TSM to have
a problem. so eventually had to reboot on the old RedHat 5.2 kernel.
They we ran "autoconf -a", brought up the TSM Library master, and
everything worked fine. So the problem is definitely between RedHat 5.2
and 5.4.
Has anyone seen a problem like this, and can give us some insight?
