Your vntab has /usr4/ but you created the file under /usr2/ so
you may want to verify if that is correct.  You can create the
swapfile from vnconfig by the way, vnconfig(8).  Anyway, assuming
that /usr2/swapfile is where the file actually is, you would add the
following to /etc/rc.conf:

swapfile="/usr2/swapfile"

Then, the following code from /etc/rc is activated:

-----
# Add additional swapfile, if configured.
#
case ${swapfile} in
[Nn][Oo] | '')
        ;;
*)
        if [ -w "${swapfile}" -a -c /dev/vn0b ]; then
                echo "Adding ${swapfile} as additional swap."
                vnconfig /dev/vn0b ${swapfile} && swapon /dev/vn0b
        fi
        ;;
esac
-----

Hope that helps.
