I believe for some reason when I created a ZFS mirror (using whole disk syntax) the EFI partition was correctly created but the FAT filesystem was not created on the mirror, and I also am not sure whether it should be automatically created.

I'll check later the exact commands but I believe that I mirrored my boot disk as follows :

zpool attach rpool c5t0d0 c5t2d0

resulting in

config:

        NAME        STATE     READ WRITE CKSUM
        rpool       ONLINE       0     0     0
          mirror-0  ONLINE       0     0     0
            c5t0d0  ONLINE       0     0     0
            c5t2d0  ONLINE       0     0     0

The point is that I later executed manually commands to create a FAT filesystem and copied manually EFI files which I think should be done automatically (and my understanding is it should have happened automatically but I think it didn't).

I also tested doing a mirror disk install using the OpenIndiana which failed, I'll open a separate bug report for that

Ideally installing onto a mirror from the OI installer would be the best solution instead of manually mirroring the boot disk .
