Followup with modified test plan:
1) Yank disk0 from V240.
Waited for it to be marked FAULTED in zpool status -x
2) Inserted new disk0 scavenged from another system
3) Ran format to set s0 as full-disk to agree with other system
4) Halted system
5) boot disk1
Wanted to make sure Jumpstart mirror

You want to install the zfs boot block, not the ufs
bootblock.
Oh duh. I tried to correct my mistake using this:
installboot /usr/platform/`uname -i`/lib/fs/zfs/bootblk /dev/rdsk/c1t0d0s0
And now get this:
Boot device: disk File and args:
Can't mount root
Evaluating:
The file just loaded

Vincent,
I think you are running into some existing bugs, particularly this one:

Now I pull out disk0 to simulate failure there. OS up and running fine, but
lots of error message about SYNC
Sounds correct to me. The disk isn't sync'd so boot should fail. If
you pull disk0 or set disk1 as the primary boot device what does it
do? You can't expect it to resliver before booting.

Ummm, could you back up a bit there?
What do you mean disk isn't sync'd so boot should fail? I'm coming from UFS
of course where I'd expect to be able to fix a damaged boot drive as it drops
into a single-user root prompt.
I believe I did try boot disk1 but that failed I think due to prior
