Identify disk on a SAS6iR controller

I'm trying to identify clearly which disk needs replacing in a RAID1 
array. The controller shows it's PhysDisk 0 id=1. When opening up the 
machine how do I know for sure which disk this is? (Ideally by serial 
number on disk and not just physical cable connected to..)

Is there a way to show the serial numbers of disks through the lsiutil 
command line utility or otherwise?

CentOS 5.4
Dell Poweredge R300
Dell (pretend) RAID SAS6iR controller (aka LSI SAS0168E)
2x WD 160Gb disks

kind regards,
