Summary - Failed Mirror Disk

Thanks to everyone who responded. Especially Gary Paveza, Thomas
Payerle, and Steven Scherbinski. I needed to know the physical location
of the disk. They pointed out to use "iostat -En" to get the serial
information. With that information, I was able to locate the disk in the
set.

Thanks everyone as usual.

Here is my original question:
