Cryptic SCSI error messages

Philippe Troin
2003-05-14T00:59:18Z

I've seen these three times over the last two weeks...

* Setup

Kernel 2.4.20 + LVM 1.0.7 (both vfs-lock and lvm patches) +
ptrace patch.

A LVM array comprising 5 SCSI discs of various sizes and makes.

This computer with this array has been working flawlessly for
over 3 years. The last disk was added to the LVM array in early
February 2003. Between February 2003 and end of April 2003, this
server has been up all the time without a single reboot.

* The problem.

1. The SCSI subsystem craps out a cryptic message:

SCSI disk error : host 0 channel 0 id 2 lun 0 return code = 10000
I/O error: dev 08:20, sector 32932328

It's always "return code = 10000" and the problem always
happens with disk 0/0/2/0.

2. Once, The SCSI subsystem queued an ABORT, failed, and the
drive "host 0 channel 0 id 2 lun 0" was taken offline.

3. LVM and ext3 crap out soon afterwards.

4. Sometimes, the crash is severe enough that the watchdog
triggers a machine reboot.

5. The drive stays stuck (not seen either in the BIOS SCSI scan
nor in the linux SCSI scan despite soft and hard resets)
until the machine is powered off and then back on.

* Questions:

- What is this error 10000 which seems to be the source of the
trouble? Is my disk dying?

- I will run more tests tonight on this disk and will report my
findings later. I intend to run a read-only badblocks, maybe
followed by a non-destructive write badblocks run (if the
read-only tests shows no problem). Any other ideas?

- Could it be a driver problem?

- And BTW, I find aic7xxx's habit of taking drives offline when
they show troubles extremely annoying: in this case it might be
justified since the drive seems to have locked up, but I've
seen it happen on CD-Rom drives which are busy retrying to read
a bad sector. Taking a CD-Rom drive offline for failing to be
responsive during I/O error recovery operation is very
heavy-handed :-)

* SCSI info:

- aic7xxx boot parameters:

aic7xxx=tag_info:{{,,,,8}}

The IBM drive has a bug with tagged queuing and anything
higher than 8 gives me trouble.
