I took the brute force approach, but it was simple and passed the boot from
either test: install on both, then mirror s0, and I'm reasonably confident
identical disks will look the same ;-)

Welcome to ZFS! In traditional disk mirrors,
disk A block 0 == disk B block 0
disk A block 1
So I spent some time trying to get the 2nd slice up on the 2nd disk... I did
manage to finally get it on there by saving the partition table to
format.dat and reformatting the 2nd disk using it, but as soon as I did the
zpool attach, it wiped out the slice 2 again. I also tried the prtvtoc and
on the target side remain.
should work fine that way,

Hmmm. I tried c5t1d0 which gave
Sounds like you've got an EFI label on the second disk. Can you run format,
select the second disk, then enter fdisk then print and post the output
here?
Thanks

It looks like we finally got it working. The log of what Mike had me do to
fix it is

case anyone else runs into this. Thanks to everyone who helped with
this.
Thanks again!

The second disk doesn't have the root pool on slice 2 - it is on slice 0 as
with the first disk. All I did differently was to create a slice 2 covering the
whole Solaris FDISK primary partition. If you then issue this command as before:
installgrub /boot/grub/stage1 /boot/grub/stage2
I have to say, looking at that confuses me a little. How can the two disks
be mirrored when the partition tables don't match?

I just tried that, but the installgrub keeps failing:

I ran into this as well. For some reason installgrub needs slice 2 to be the
special backup slice that covers the whole disk, as in Solaris. You actually
specify s0 on the command line since this is the location of the ZFS root, but
installgrub will go away and try to access the whole disk
Have you verified that it will auto failover correctly if one is s0 and one
is s2?

I've always done a disksuite mirror of the boot disk. It's been easry to do
after the install in Solaris. WIth Linux I had do do it during the install.
OpenSolaris 2008.05 didn't give me an option.
How do I add my 2nd drive to the boot zpool to make it a mirror?

Hi Tom,
You need to use the zpool attach command, like this:
# zpool attach pool-name disk1 disk2

It is also necessary to use either installboot (sparc) or installgrub (x86)
to install the boot loader on the attached disk. It is a bug that this
is not done automatically (6668666 - zpool command should put a
bootblock on a disk added as a mirror of a root pool vdev)
