Red Hat 7.3 - kernel and st driver 2003-10-07 - By Hughes, Tim M CONT
Back
I've got a Compaq (HP) DL380G2 running RH7.3 with an Adaptec2940 card in it,
with an HP LTO tape drive. It was running the default kernel (2.4.18-3smp)
on it until recently. I've always had problems with the attached tape
drive. After a reboot I would have to run "/sbin/modprobe
scsi_hostadapter1" to get it to find the tape drive and add it as a device.
It would stop working at random, where I couldnt issue any mt or dump
commands. The logs would indicate:

It would repeat this indefinitely until reboot. I found a bug posting under
Red Hat 8 (79027) that talked about problems with the older kernels so I
went and pulled the latest 7.3 kernel (2.4.20-20.7smp) and installed.
Initially, things seem to be going well. For the first time, the OS picked
up the drive(r) and installed it.

I used mt to eject the tape a few times and considered the matter resolved.
Now I appear to be back to where I started... here is another snip from the
