FYI.
Before a certain rev, if you zpool upgrade, you have silently invalidated
your grub boot blocks, and you simply need to know based on past experience
that you need to installgrub.
After a certain rev, the system will notify you with a helpful informative
message. "You need to installgrub" or something like that.
And after yet a later rev... It does the installgrub for you automatically.
Or maybe I'm just talking about starting a new mirror of rpool. Maybe the
same thing is not true in regards to zpool upgrade. I don't know for sure.
In any event... You need to do something like this:
installgrub /boot/grub/stage1 /boot/grub/stage2 /dev/rdsk/c1t0d0s0
(substitute whatever device & slice you have used for rpool)
