I found this great answer on for how to find a failed drive by using sas2ircu utility.
http://serverfault.com/a/644165
First discover the Index of your HBA card. Mine is 0
Display details of your disk. I matched my bad one based on the serial number given by smartctl -a /dev/da11
Then it was just a matter of turning on the blinking red light using the enclosure and slot light
Once you replace the drive turn off the light.
Very handy because I didn't write any serial number down when I built it.
