    He's what I use on our 690 2 lpar system. When one lpar has the media
    drawer, I use this script to do the mksysb on the other.

    #!/bin/ksh -x

    mkfifo /tmp/pipefile

    mksysb -i /tmp/pipefile &

    sleep 120
    dd if=/tmp/pipefile | rsh <hostname of system that has the drive> dd
    of=/dev/rmt0 obs=1024

    rm /tmp/pipefile
