Dr. Blinn noted "If you boot from the installation media, then you should
be able to get to
the AdvFS software and restore enough of it to use commands like "addvol"."
So perhaps it is not as critical to only have one volume on /usr as I had
first thought.
It seems I missed a couple of steps. Here is the revised list of commands.
vdump -D /usr/local -f /work/local.dump
(verify the dump)
rm -r /usr/local (or rm -rf /usr/local)
mkdir /usr/local
chown root.system /usr/local
chmod 0775 /usr/local
rmvol /dev/rz3g usr_domain
mkfdmn -x 2048 -p 2048 /dev/rz3g local_domain
mkfset local_domain local
mount -t advfs local_domain#local /usr/local
cd /usr/local
vrestore -f /work/local.dump
(edit fstab to reflect changes)
