Hello all, I am running SUSE 9.0. I am having some problems with a recently installed HP Surestore DAT 40. When I try and run a backup, the computer freezes, slowly at first and then progressively gets more locked up. Here is what happens. Start Backup BU software starts the jobs and hits a good xfer rate. Usually within 30-50 seconds of starting the job the backup throughput falls and eventually goes to 0. The tape drive stops receiving data (light stops flashing). The backup software interface still functions but becomes increasingly unresponsive. Same with the GUI interface. Eventually all user interfaces lock up. If I run a very small backup job (like the htdocs directory) it will work fine. Any larger job causes the hang. No matter how long I wait, the software never generates and error message. Also, nothing in any of the log files I checked to say what is happening. This box has apache and qmail running on it as well. When it is locking up, I can still access the apache test page text, but the graphic won't load. I can telnet to qmail but it won't send any mail. Here is the setup. Compaq Smart 2SL attached to 2 x 9 GB drives in RAID 1 and 1 36 GB drive. HP DAT is connected to on board Adaptec 7860 controller along with a NEC cdrom drive. The CD is the last device on the chain. Backup software tried (both Tapeware and Arkeia). All drives appear as expected. I can format tapes in the drive and have been able to work with as expected until I start a backup job. I suspect it is a hardware issue. The 7860 is a ultra/narrow controller whereas the DAT drive is a Ultra/LVD drive. Is it possible that this is the cause? Could the location of the DAT on the cable be a problem, should it be last? This server also has a 7890 on-board controller that is Ultra/LVD, but when I enable it the machine won't boot to the Compaq raid controller. I think I need to disable some stuff in the scsi bios to fix that problem, but I haven't had time. The compaq 2sl also has a second channel, but the documentation that came with the dat suggests you shouldn't connect it to a raid controller if possible. Any suggestions on where to look for this problem would be helpful. Thanks in advance. rotbau _______________________________________________ TCLUG Mailing List - Minneapolis/St. Paul, Minnesota Help beta test TCLUG's potential new home: http://plone.mn-linux.org Got pictures for TCLUG?
