get drive serial numbers from NetApp DS4243 shelves strapped to Linux server

When doing data recovery on a failed 3Ware RAID group, I utilized a couple spare NetApp DS4243 shelves. I put all the SATA drives into brackets, popped a quad port SAS card into a 1U server, and booted my rescue image from the network. The Debian OS was able to see each individual drive, at which point I could make ddrescue copies, and edit the 3Ware DCB metadata using hexedit. Keeping everything straight was quite a challenge. This one liner helped me find all the serials, and get the copies sorted out:

# for i in `ls /dev | grep sd | sed -e 's/[0-9]//' | sort -u`; do echo -n "/dev/$i " ; smartctl --all /dev/$i | grep "Serial number" | awk '{print " --- " $3}'; done;
