It's pretty easy to find via google.
# /usr/sbin/zpool attach rpool (currentdev) (newdev)
# /usr/sbin/installgrub /boot/grub/stage1 \
Note that (newdev) must be a slice.
You might get an error message from zpool about slice 2 (s2)
overlapping newdev - assuming that you have setup your newdev
slicing correctly, you can re-issue the zpool command thusly:
# /usr/sbin/zpool attach -f rpool (currentdev) (newdev)
