>From my notes from mirroring a new install (I install first then mirror).
You won't need pfexec if your super-user.
Inside format, fdisk twice first time delete anything there, second time it
will ask you if you want to install a default Solaris2 setup.
Obviously change the disk id to match your system.
pfexec format
fdisk (delete if required) and install standard Solaris2
pfexec prtvtoc /dev/rdsk/c1d0s2 | pfexec fmthard -s - /dev/rdsk/c2d0s2
pfexec zpool attach -f rpool c1d0s0 c2d0s0
I've never put a ZIL on the same disk, so can't help there sorry.

Subject: [zfs-discuss] zil and root on the same SSD disk
Hi
got a brand new server with 14 x 2TB disk, and 2X160GB SSD disk , my plan
was to install opensolaris on one of the SSD disk and then zfs mirror the
root disk onto the second SSD disk , but since the server will handle some
sync NFS write i also want to add a zil log on the same SSD disks, also
mirrored. I don't have in depth knowledge on solaris or opensolaris , and
don't know much about how partitions works on solaris. I have tried the last
2 days solving this , and reading howtos on the net , but have not been able
to find any step by step howto explaining how I should do it. :-(
I have tried creating on big solaris2 partition , and then used 140G to the
system , and then make a new slice the my zil , witch looked to work , at
least i could add the 20G slice as log device to my pool , but then the
problem came when i tried to to clone the partition map from the system SSD
to the second SSD disk with this command
prtvtoc /dev/rdsk/c7t0d0s2 | fmthard -s - /dev/rdsk/c7t1d0s2
it said something about overlapping partitions/slices ( unfortunately i did
not save the output of the error )
but what is the right way to do this , should i create one big solaris2
partitions and then slice it up or should I create 2 separate partitions ,
and what is the right way to mirror both the system disk and zil log to the
second SSD disk. And is i possible to do the partitioning from the installer
? ( I am installing opensolaris from the Live CD)
please , hoping someone could provide me with a nice step by step howto on
this , or maybe guide be through.
