Surestore DAT 40i (C5683A)

[CA1117625]

Hi,
my system:
OS: SuSE 8.2, kernel 2.4.20
CPU: Intel PIV, 2.40 GHz
SCSI-Contoller: Dawicontrol DC-2976 UW with automatic hostadapter termination
Tape-Device: HPSurestoreDAT 40i (C5683A) Rev: C111
Backup with crontab and tar-script
My problem:
Sometimes my backup works fine.
In my backup script I start with
"mt -f /dev/st0 status". The response of status is o.k., but the next step in my script "/bin/tar ..." didn't start.
I seems that the complete scsi systems hang.
No command to "/dev/st0" or tar works. In my "messages" file I see "SCSI bus is beeing reset for host 1 channel 0. SCSI host 1 abort (pid xyz) timed out - resetting".
Only a "shutdown -h now" helps.

Can I install the hp_ltt34sr1a_linux.tar to test the drive and get more information ?
Or any other idea ?
Thanks

L&TT is tested on RedHat, it may work also on Suse but have no info related.
Reading your post you have a SCSI controller with automatic hostadapter termonation, I do not know exactly what you mean, but a scsi bus should be terminated at both end, so you need to have a terminator on the HBA ( I suppose is the automatic terminator yo spoke aabout) and a terminator at the end of the scsi cable after the last device. Please check that you have a scsi cable with build in terminator (a small box at the end of the cable).
Missing this terminator will give you the behaviour you described

Hello,
I changed to the type of cable described in your message. Now I am testing the new configuration.
Thanks for your help
