write errors on secondary scsi LUNs

[Arjen Wolfs <arjen@xxxxxxxx>]

Hi,

I have two hardware raid partitions, on an identical SCSI ID; one with LUN 
0, one with LUN 1. The partition on LUN 1, which consists of brand new hard 
disks, is generating random write errors of the kind:

SCSI disk error : host 2 channel 0 id 0 lun 1 return code = 8
 I/O error: dev 08:21, sector 310378498
XFS: device 0x821- XFS write error in file system meta-data block 
0x12800002 in sd(8,33)

SCSI disk error : host 2 channel 0 id 0 lun 1 return code = 8
 I/O error: dev 08:21, sector 310397560

Oddly enough, xfs_check and xfs_repair can't find anything wrong with it 
after this happens. Considering kernels before 2.4.10 would not even 
recognize SCSI devices on LUNs other than 0, I am not entirely sure wether 
this is an XFS or a SCSI issue. Anybody have any ideas?

TIA,
