Hi Dale,
It worked. Prtvtoc is already set right.
# zpool attach export c2t0d0s5 c2t2d0s5

(I presume that you meant to use c2t2d0s5 as the second slice)
You've already created your pool, so all you want to do is attach the
new slice to be a mirror of one that is already in the pool:
zpool attach export c2t0d0s5 c2t2d0s5
This will create a mirror between c2t0d0s5 and c2t2d0s5
First be sure that slice 5 on c2t2d0 is at least the same size as
c2t0d0s5. If c2t2d0 is unused, you can copy the vtoc from the first
disk to the second one with a simple command:
prtvtoc /dev/rdsk/c2t0d0s2 | fmthard -s - /dev/rdsk/c2t2d0s2
Since you're on x86, you may need to run fdisk against c2t2d0 if it is
a virgin drive.
