determining which disk failed in software raid

[lee_connell]

What is the proper way to determine which physical disk has failed in the system? I know it tells you /dev/sda or /dev/sdb is the failed disk but how would I determine which "physical" disk that is inside the server?

I am running sata II disks in software raid1.

I tried using lshal to get details on the drives like maybe a serial number but that didn't help. Any suggestions?

It usually works that the primary sata controller will be sda, secondary sata sdb and so on

Thank you this is what I expected, just wasn't sure :)
