Dear sysadmin lazyweb: I'm using a MegaCLI RAID controller and need to find the serial number of a failed drive as written on the drive enclosure so I can replace it. Does anyone know the magic voodoo for this? (I can also accept getting serial numbers of all non-failed drives)

Helpful replies in this thread plus futzing led me to a winning invocation: smartctl -d megaraid,0 -a /dev/sdb Which seems to work, where a vanilla "smartctl -a /dev/sdb" gave a nonsensical serial number. To all who helped me, long may your drives spin with no errors.

I could tell you how to do this in FreeBSD but every encounter with disk stuff in Ubuntu has resulted in my tearing my hair out and reassigning the alert/ticket to someone else in our group with more specialized knowledge. I hate megacli with the fiery passion of a thousand suns.
