The OpenSolaris installer is not capable of creating the mirror at install
time. The mirror had to have been created my hand after the installation
with a "zfs attach" command. It appears that there may be a problem with
the way ZFS did the attach when this was first created and several others
have seen similar issues (along with the fdisk partition being set to EFI).

The fdisk output for c5t1d0 is missing. The output above shows c5t0d0
in both cases. It might still be useful to see the fdisk info for
c5t1d0 but it probably isn't the problem here. What I believe may be
the problem is that grub expects to put stage1 and stage2 on the device
starting at partition 0 sector 0 but on this disk (c5t1d0) there is no
partition starting at 0. I think what you may have to do is detach
c5t1d0s0 from the mirror and use format to add a partition starting at
0 (probably using 0 - 255) and then attach c5t1d0s0 to the mirror again.
However there have also been some issues with doing a ZFS detach and re-attach
of disks to the morror so you may want to follow the steps that Dan price sent
out last week.
I hope this is helpful!

Dan's suggested steps:
If you want to remove an EFI labelled disk from your root pool, my advice
to you would be to do the following. Note that I have not tested this
particular sequence, but I think it will work. Hah.
0) Backup your data and settings.
1) 'zpool detach' the EFI labelled disk from your pool. After you do this
YOU MUST NOT REBOOT. Your system is now in a fragile state.
2) Run 'zpool status' to ensure that your pool now has one disk.
3) Edit /etc/boot/solaris/filelist.ramdisk. Remove the only line in the
file:
etc/zfs/zpool.cache
4) Delete /platform/i86pc/boot_archive and /platform/i86pc/amd64/boot_archive
5) Run 'bootadm update-archive' -- This rebuilds the boot archive,
omitting the zpool.cache file.
It may also be necessary to do installgrub at this point. Probably, and
it wouldn't hurt.
6) Reboot your system, to ensure that you have a working configuration.
