Well, I thank you all for the ideas. We don't have the /etc/stinit.def file
so changing/editing that is out.
I think I have a plan of attack now.

1) we will try the latest Adaptec driver (6.3.9) if it works great
    if not
2) next we will try the "old" adaptec driver (aic7xxx_old)
    if that doesn't work
3) we will go to our LSI cards again
   if htat doesn't work ...... I would hate to have to try Win 2k3

If you have more ideas send them along. I'll keep you all posted as to our
progress and
if we find a resolution I'll post instructions on how to implement it.

Ken

Subject: [Networker] Very Frustrating Problem


> We are running Networker 6.1.4 (upgraded from 6.1.3 etc) on RedHat AS 3.0
with the latest kernel 2.4.21-27.0.2.ELsmp and we have also tried the 2.4.29
kernel. The Jukebox is a Storagetek L-80 with 8 SDLT drives (set up 2 per
scsi channel and the picker on its own channel). The scsi cards are 3
Adaptec 39160 cards (we've also tried Buslogic cards). The computer is an HP
ML370 with 6GB of memory and about 200GB of disk and dual  2.8GHz
processors. We've also tried this with similar Dell hardware (Dell 4600
configured about the same as the HP).
>
> Now to the problem. We keep getting an inordinate number of scsi bus
resets (varies from 6 to 20 per day). We get tape drives that disappear (no
device present) or get into a state where they are useable but you can't
eject the tape.
>
> We've tried a lot of configuration changes and are now experimenting with
changing the command queueing depth to the tape drives (we've tried the
default of 32 as well as 16, 8 and 4 all with no success).
>
> Has anyone seen this type of problem or behavior? Did you manage to
resolve the problem? How?
