it's not exactly doc, but here's my recipe for
cooking solaris7 software raid1 partitions with
disksuite... and a little perl script that you can
use under cron so you know when disks die. use
at your own risk.

Solaris7 + DiskSuite 4.2 Disk Mirroring Cookbook
#==================================================================
# Install and Initialize DiskSuite
#----------------------------------------
# install disksuite...
# mount Easy Access Server 2.0 CD
cd /cdrom/cdrom0/products/DiskSuite_4.2/sparc
pkgadd -d `pwd` # install SUNWmd (1) and SUNWmdn (3)
# add /usr/opt/SUNWmd/bin:/usr/opt/SUNWmd/sbin to PATH in /etc/profile
#----------------------------------------
# steal space from swap to make one tiny
# partition on each disk for the state db...
# this assumes that swap is slice 3...
# if not, adjust these instructions accordingly...
shutdown -g0 -i0 -y
boot -s # at the ok prompt
swap -l # note the swap slice
swap -d /dev/dsk/<slice>
swap -l
format # shrink slice 3 by about 8-10 cyclinders and and
# use the resulting cyclinders to create slice 4
# (doc sez the databases are under 1 meg)
format # format the secondary disk
prtvtoc /dev/rdsk/<slice> # verify the new slice
#----------------------------------------
# make two state databases on each s4 partition....
metadb -a -f -c 2 c0t0d0s4 c0t1d0s4
#----------------------------------------
# check state databases...
metadb # should print four lines of info about c0t0d0s4 c0t1d0s4
#==================================================================
# Create Mirrored Boot/Root Filesystem (on c0t0d0s0 and c0t1d0s0)
# slash on slice 0...
