Critical: SCSI reset problem
Hi, I see the following on my console. SCSI host 1 abort (pid 1207191) timed out - resetting SCSI bus is being reset for host 1 channel 0. ncr53c8xx_reset: pid=1207191 reset_flags=2 serial_number=1207192 serial_number_at_timeout=1207192 SCSI host 1 abort (pid 1207201) timed out - resetting SCSI bus is being reset for host 1 channel 0. The system hangs because of the resets. The problem repeats time by time. I run K210 under linux-2.4.23-pa5. The problem appears on different scsi controllers, so I hope there are neither controller nor disk problems. This are current drivers from /var/log/messages. kernel: loop: loaded (max 8 devices) kernel: Found i82596 at 0xffd07000, IRQ 87 kernel: eth0: 82596 at 0xffd07000, 08 00 09 DA 44 88 IRQ 87. kernel: 82596.c $Revision: 1.32 $ kernel: SCSI subsystem driver Revision: 1.00 kernel: zalon_scsi_callback: Zalon vers field is 0x1, IRQ 35 kernel: ncr53c8xx: 53c720 detected kernel: ncr53c720-0: ID 7, Fast-10, Parity Checking, Differential kernel: zalon_scsi_callback: Zalon vers field is 0x1, IRQ 36 kernel: ncr53c8xx: 53c720 detected kernel: ncr53c720-1: ID 7, Fast-10, Parity Checking, Differential kernel: scsi0 : ncr53c8xx-3.4.3b-20010512 kernel: scsi1 : ncr53c8xx-3.4.3b-20010512 Can it be a bad driver problem? I use Linux Software RAID, is it possible to tune some parameters there? Many thanks in advance for any help! BR, Dub _ Add photos to your messages with MSN 8.

The system hangs because of the resets. The problem repeats time by time. Well, I don't want to scare you, but the only time I've ever had this problem was when one of the disks in my RAID array was failing. (I run RAID 0 which is, of course, asking for trouble) I'm sure that there are other things that can cause this, but I only saw it during my disk failure. The drive would try to read for a while, fail, and cause a SCSI bus reset which would require a reboot. (If your root drive isn't a SCSI device AND if you have SCSI support loaded as a module, just removing and re-loading the SCSI module SHOULD work.) -- Alex Malinovich Support Free Software, delete your Windows partition TODAY!

SCSI Reset.
I've just aquired a new external scsi hard drive, and I was wondering if there is any way I can add it to my chain w/o losing my uptime? Is there some utility to reset the bus or to re-poll the ID's? thanks in advance. -Dan

Is there some utility to reset the bus or to re-poll the ID's? What is your SCSI adapter? With Adaptec 2940U2W's I've had good luck at this, *provided* that I pre-partition it on another machine, and I add it at a higher ID than the stuff that's running already... the adapter detects the change and the kernel rescans for devices. Other adapters may require you to echo something to /proc/scsi/(whatever-- not standardized) to cause a bus reset. Thanks for the suggestions. I have an old Adaptec 1452CP. The driver doesn't seem to support the proc-fs: [EMAIL PROTECTED]:[/proc/scsi/aha1542]$ ls 0 [EMAIL PROTECTED]:[/proc/scsi/aha1542]$ cat 0 The driver does not yet support the proc-fs Also, by than stuff that's running already do you include the host adapter? If so, I'm SOL because my host is on ID 7. I've tried adding the new drive on ID 6 and mounting it, and it doesn't seem to work. It is formatted fat16 already. My only experience with this is on solaris where there was a command to poll the SCSI id's (I think solaris 2.5) that could be called by root at any time. -Dan

Could you give the actual failure message? Hallo Sometimes I have the same problem (Adaptec 2940u). But it doesn't happen on every reboot. Somewhere in the Suse dist. 4.2 there is a hint to solve the problem but I couldn't find it again. I think it was like this: Give the kernel the boot parameter aic7xxx=noreset. (aic7xxx is the driver for my scsi adapter) Then the scsi adapter will not make a reset again. Hope that's right and will help you.

Could you give the actual failure message? We had a client with a similar problem with one of our cards. Turns out that his sound card wasn't fully honoring the bus reset, and was grabbing the IRQ out from under the Cyclades card. From a power-on start, the system worked fine, but after a three finger salute, or even pushing the reset button, the card didn't work. Something like this would hang your system if the SCSI card suddenly found itself without the IRQ it was set for... and sound cards LOVE to grab IRQ 11. It works with DOS does not mean that there is not a hardware conflict. The DOS drivers probably initialize the hardware differently. Standard procedure is to pull out everything except the minimum necessary to boot (plus the offending card, if not a required card). Add cards until the problem resurfaces. -- ++ | Technical Support Engineer, Cyclades Corporation | | 800/88-CYCLADES (882-9252) or (510)770-9727, x258 | | Maker of High Performance Multiport Serial Cards | | Unsolicited mail ads subject to a $25 handling fee | ++

This is with two flavors of Slacware and with Debian. It seems to be a problem that my SCSI adapter has with Linux in general.

System hangs on SCSI reset (AHA 1522).
Problem: The system hangs when the SCSI bus is reset. Config: Adaptec 1522 SCSI controller Two different motherboards Three different versions of Linux More specifically, I cannot perform a soft reboot from Linux. If, for example, I run 'shutdown -r now' the system will shut down normally, but will hang during the boot phase just after it recognizes the SCSI controller. I can reboot DOS to DOS, but if I am running DOS and reboot to Linux the system hangs in the same place. Shutting off power and then rebooting clears the problem. Any clues or comments?
