Well, when you run : 
# zpool upgrade yourpool

it will not print a lot of things, but it will end with :

If you boot from pool 'yourpool', don't forget to update boot code.
Assuming you use GPT partitioning and da0 is your boot disk
the following command will do it:

        gpart bootcode -b /boot/pmbr -p /boot/gptzfsboot -i 1 da0

All you have to do is adapt it to run your particular setup, replacing da0
with the correct disk (and running it for each disk where your pool is, in
my case, it was mfid0 and mfid1.)
