Since the rpool can not use EFI labels you need to format the mirror disk so
it is the same as your rpool disk.
Example and your disk target will/may differ.
prtvtoc /dev/rdsk/c7t0d0s2 | fmthard -s - /dev/rdsk/c7t1d0s2 (s2 is the
whole disk)
Then just attach the disk to be mirrored
/usr/sbin/zpool attach -f rpool /dev/rdsk/c7t0d0s0 /dev/rdsk/c7t1d0s0
If you want to be able to boot from the mirror as a CYA then run install grub
installgrub -m /boot/grub/stage1 /boot/grub/stage2 /dev/rdsk/c7t1d0s0
The following will show the progress of the resilvering
zpool status
