    I have performed ~15 migrations from 4.3.3 to 5.2.0. The only problems
    I have had are with applications on the servers and not with the OS
    itself. Make sure your firmware is current before doing the migration.

    If your rootvg is mirrored, unmirror it.
    Be sure the CD-ROM microcode is updated.

    E-mail me at com and I'll send you my project plans
    from my upgrades. I did at least 5 over the past 3 months.

    5.1 has been around for over two years now so it's pretty mature.
    I've done a lot of upgrades and had very few problems.

    can you explain your logic in this? I've only done a handful of upgrades,
    but having rootvg mirrored didn't matter a bit, save for remembering to
    bosboot -ad the mirrordisk.

    ... unless you're using alt_disk_install as a upgrade or fallback method, I
    don't see the point.

    BV, is the unmirrowing a prereq for upgrade...what sort of problem did
    you run into?

    Thanks

    We have all the servers here mirrored, but the servers do not generally
    have four disks internally. So I break the mirrored pair and upgrade
    on only a single drive. I'm exposed while the upgrade is going on,
    but as you pointed out I have a built-in fallback method. If the app
    does not run in production with the new OS version, I boot back to
    the original os and re-mirror.

    After upgrading my H80 to 5.2, the system hung and would not reboot.
    I called IBM after about an hour of troubleshooting. We determined
    that the SSA adapter fileset did not get upgraded, and as well, the
    bos.mp for some reason did not get upgraded. I also discovered that
    for some reason, /tmp was missing from /etc/filesystems. The IBM tech
    informed me there was a known issue upgrading to AIX 5 on system with
    rootvg mirrored. As of November, 2003, there was no fix from IBM. We
    determined that was not the case with my system, forced these 2
    filesets to be applied, I added a "/tmp" stanza to /etc/filesystems,
    then booted. No problems.

    If you get the "bug", the system will not boot. fsck will run on all
    filesystems and might even fix things, but the filesystems still will
    not mount. The only fix as of November, 2003 was a mksysb restore and
    try again. The way around the "bug" was to unmirror rootvg first.

    I've had one "huh?" on both of the systems I upgraded from
    AIX 4.3.3-11 to 5.1.0-04 (and then ML05). I run "diag" (or boot into service
    mode), select "Task Selection", and get:

    ....snipped
    Run Diagnostics
    Run Error Log ysis
    Display or Change Diagnostic Run Time Options

    ** CATALOG ERROR ** (68)
    Add Resource to Resource List
    ....snipped

    Anyone have any idea what that "CATALOG ERROR" line is all about?

    Thanks,
    Steve

    Message text is stored in catalogs (*.cat) files.
    The smit & diag panels can use these catalogs to
    get the text to be displayed for panel entries.
    There are catalogs for each locale (e.g. en_US,
    de_DE) and usually for each fileset.

    I would suggest taking a look at the filesets:
    bos.msg.en_US.diag.rte
    and
    devices.msg.en_US.diag.rte
    (substitute your $LANG for en_US).
    One or both of these may not have been updated to 5.1,
    and if they are old (or not installed at all), then
    the 'diag' command can't find the right text to
    display for message #68.

    lslpp -h | grep diag | grep msg
    lppchk -f bos.msg.en_US.diag.rte
    lppchk -f devices.msg.en_US.diag.rte

    If they are not installed, install them from the
    5.1 base media and then apply ML5 again.
