I did that a year ago. Here's my transcript:
<root@qtpie># /sbin/bootadm install-bootloader -Mfv -P rpool
be_do_installboot: device mirror-0
be_do_installboot: device c5t0d0s0
Command: "/usr/sbin/installboot -F -m -f //boot/pmbr //boot/gptzfsboot
/dev/rdsk/c5t0d0s0"
Output:
bootblock written for /dev/rdsk/c5t0d0s0, 323 sectors starting at 1024 (abs
26112)
stage1 written to slice 1 sector 0 (abs 12544)
stage1 written to master boot sector
be_do_installboot: device c5t1d0s0
Command: "/usr/sbin/installboot -F -m -f //boot/pmbr //boot/gptzfsboot
/dev/rdsk/c5t1d0s0"
Output:
bootblock written for /dev/rdsk/c5t1d0s0, 323 sectors starting at 1024 (abs

My root mirror looks like this:

mirror-0 ONLINE 0 0 0

To be sure all is okay, try booting from one disk and then the other.
