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)
