HP StorageWorks Ultrium 1760 hangs machine
Drive is an HP StorageWorks Ultrium 1760 (LTO) with 1.6TB tapes. Tape
operates normally for a period then, whilst the tape isn't in operation,
the machine hangs and /var/log/messages contains:
Aug 30 14:55:56 aws1 kernel: irq 169: nobody cared! (screaming interrupt?)

Aug 30 21:53:40 aws1 kernel: Recovery SCB completes
and that's the last entry before the reboot.
I tried turning
ACPI off and reducing the speed of the SCSI bus to 160 all to no avail.
Kernel details:
[root@aws1 ~]# uname -a
Linux delhi-aws1 2.6.9-67.ELsmp #1 SMP Wed Nov 7 13:58:04 EST 2007 i686
i686 i386 GNU/Linux
-----------------------------
I hope someone could help me to solve this problem.

Re: HP StorageWorks Ultrium 1760 hangs machine
I don't see anything there that I can diagnose but if you can pull the logs from the drive shortly after a failure maybe they will give us something additional if there is unusual SCSI bus activity.
It looks like the OS is attempting to abort a TESTUNIT READY command which is a pretty trivial "are you alive and ready" ping. Not typically something where an error would occur.
HP Library and Tape Tools is the utility for pulling the drive logs using the "Support Ticket" function. It works on several Linux versions but i don't recognize yours so I'm not certain if it would work for you or not. It is available at http://www.hp.com/support/tapetools

Re: HP StorageWorks Ultrium 1760 hangs machine
Thanks, Curtis. The Linux version we are using is RadHat4.6. I noticed that a new firmware version was published early this year. I was wondering if updating the firmware would be helpful or not?
