    Once we wrote a script (as in play) for the sequence of steps to
    reach the end goal, the whole deal was easy. Now I'm working on
    a script to add maintenance level upgrades to each of the servers.
    I can post my script if it would help.

    Certainly. I don't think my company would have a problem with that.
    It's not pretty and formatted. It's a checklist of what I did for the
    upgrade.


    # prepare for upgrade
    mount txwast01a:/export/nim/mksysb /mnt
    rm /mnt/txspf111_mksysb
    time mksysb -i /mnt/txspf111_mksysb
    umount /mnt
    time mksysb -i /dev/rmt0
    make tsm backup (dsmc i)
    unmirrorvg -c 1 rootvg hdisk1
    bosboot -ad /dev/hdisk0
    lsvg -l rootvg

    nimadm
    bootlist -m normal hdisk1 hdisk0
    bootlist -m normal -o

    # load the new os and test
    reboot to hdisk1
    oslevel (should read 5.2.0.0)

    # go forward after the upgrade
    bosboot -ad /dev/hdisk1
    copy /usr/sbin/alt_disk_install from nimadm master to nimadm client
    chmod 755 alt_disk_install
    alt_disk_install -X old_rootvg
    lsvg (old_rootvg is gone)
    lspv (hdisk0 is not assigned to a vg)
    extendvg -f rootvg hdisk0
    mirrorvg -c 2 rootvg hdisk0
    lsvg -l rootvg to check for stale
    bosboot -ad /dev/hdisk0
    bosboot -ad /dev/hdisk1
    bootlist -m normal hdisk0 hdisk1
    * for every stale lv run syncvg -l STALELV

    # fallback to the previous os
    bootlist -m normal hdisk0 hdisk1
    reboot to previous os
    oslevel (should read 4.3.3.0)
    smitty (to remove failed os vg)
    extendvg rootvg hdisk1
    mirrorvg -c rootvg hdisk1
    bosboot -ad /dev/hdisk0

    What is 5.2.2? Do you mean 5200-02 ?

    I have a spreadsheet project plan I created to do this. E-mail me and
    I'll send it to you.
