Yup, you're right, you want to use the 'add' form of the command, but the basic idea stands, just add the names disks to the aggr, and you can force them into a new raidgroup as well.

Yeah, that will do it as well, since you could just bounce the number back up and add in the rest of the disks. Maybe not as ideal is specifying a new raid group when adding disks, but not bad either.
