"WD30EFRX" is the model number of disks, as reported to the system by
the disk firmware. What follows is the individual serial number.

Since they're all the same make and model, I'd strongly recommend
restarting the install process with Ctrl+c, and choosing "Shell" from
the menu. At the shell prompt, use `gpart show` to get a list of
attached disks and their partitions, and note the drive letters of the
two empty disks (daX and daY) you want to use. Then you can type "exit"
and proceed with the installation.
