I just documented mine for Solaris 8. This is using Solstice Disk Suite. The drives are c1t0d0 and c1t1d0. Hope this helps.

Install Solstice disksuite from Solaris Software, disk 2 of 2.
#cd /cdrom/sol_8_202_sparc_2/Solaris_8/EA/products/DiskSuite_4.2.1
1. run ./installer
2. default install (place in /usr/sbin) and allow reboot
Run commands below:
# prtvtoc /dev/rdsk/c1t0d0s2 | fmthard -s - /dev/rdsk/c1t1d0s2
(This causes the mirrored disk to have the exact format as the main root disk).
Run format and check that BOTH internal disks match exactly. If not, this will fail.

BOTH internal drives need to match exactly.

# metadb -a -f c1t0d0s7
# metadb -a c1t1d0s7
# metainit -f d10 1 1 c1t0d0s0
d10: Concat/Stripe is setup
# metainit -f d20 1 1 c1t1d0s0

d26: Concat/Stripe is setup
# metainit d6 -m d16
d6: Mirror is setup

# echo �set md:mirrored_root_flag=1� >> /etc/system

edit /etc/vfstab. Use the /dev/md/dsk/d0 (or 1/3/4/5/6) instead of c1t0d0s0 (or 1/3/4/5/6)
reboot

run following commands:
# metattach d0 d20
d0: submirror d20 is attached
# metattach d1 d21
d1: submirror d21 is attached
# metattach d3 d23
d3: submirror d23 is attached
# metattach d4 d24
d4: submirror d24 is attached
# metattach d5 d25
d5: submirror d25 is attached
# metattach d6 d26
d6: submirror d25 is attached

Check progress of mirror sync. The mirroring takes 2-3 hours.
# metastat|grep -i progress

While waiting, run metastat -p | tee /etc/lvm/md.tab (captures DiskSuite config)

Then run # dumpadm -d /dev/md/dsk/d1

NAME

       install-solaris - install the Solaris operating system

SYNOPSIS

       install-solaris

       install-solaris	invokes  the  Solaris  Install	program. Depending on graphical capability and available memory at the time of invocation,
       install-solaris invokes either a text-based installer or a graphical installer.

       The following minimum requirements for physical memory dictate which features are available during installation:

       For SPARC machines:

       128 MB

	   Minimum physical memory for all installation types

       128 MB

	   Minimum physical memory required for windowing system

       384 MB

	   Minimum physical memory required for graphical-based installation

       For x86 machines:

       256 MB

	   Minimum physical memory for all installation types

       256 MB

	   Minimum physical memory required for windowing system

       512 MB

	   Minimum physical memory required for graphical-based installation

       In some cases, even if the minimum physical memory is present, available virtual memory after system startup can limit the number  of  fea-
       tures available.

       install-solaris	exists	only  on  the Solaris installation media (CD or DVD) and should be invoked only from there. Refer to the  for more
       details.
