Subject: puzzling scsi return code 20000
Date: Mon, 05 Jul 2004 14:07:43 +0200	[thread overview]
Message-ID: <40E9448F.1090700@univ-nantes.fr> (raw)

hello. I have some problems with a SAN here. Don't know if the problems 
lies in scsi code/driver or other thing...

The setup is :
a QLA2300 (Fibre channel) with 6.0.64 driver from qlogic site,
2.4.26 kernel, device mapper 1.0.17 applied,
and xfs or reiserfs on top of lvm volumes (using evms)

This setup seemed fine since some months now, with giga of data moved 
every day, but I noticed this on the log:

Jun 22 16:45:15 talisker kernel: SCSI disk error : host 3 channel 0 id 2 
lun 1 return code = 20000
Jun 22 16:45:15 talisker kernel:  I/O error: dev 08:10, sector 145423312

I have two of these errors in the last month. What's the meaning of this 
return code ? I made
badblock on the /dev/evms volume, and all is OK.

I also performed a disk scan on the raid array, (an IFT 7250F) and there 
are no errors.

The machine can be quite heavily loaded. May I suspect the qla driver ? 
May I suspect the underlying LVM. The LVM has been resized by the 
past... Can an error happens here too ?
I'm very puzzled...

This is just a summary . I can furnish more information if needed.
