timeout on unoccupied Raid port - ahcix861 error



Hi,

I have hundreds of errors on any given day with my new 2003 SBS R2
installation relating to a timeout on device/scsi/ahcix861.

This seems to relate to my Raid drives. When I am checking these, I find
that my 2 drives are on ports 1 and 2 and that some services are trying to
write to port 0, getting the following error message on my Raid monitoring
software (WebPAM): Task 20 timeout on disk (Port Number 0,Target ID 1) at LBA
0x0340f3f (Length 0x100)

Any suggestions?

Many thanks,

Yann
