    Their comments/Guideline below are valuable & pointed
    me to where I will try to do in the next upgrade.

    ----------------------------------------
    You can not upgrade the Operating System using the
    standard method while running a Logical Volume Manager
    (Solstice or Veritas or volume manager).Solution:You
    can either convert your meta devices back to standard
    disks or leave the meta devices as is and use Live
    Upgrade
    (http://www.sun.com/blueprints/0302/upgrade20-2.pdf).
    Live Upgrade is volume manager aware.

    -------------------------------------
    You don't need to remove disksuite (specifically, the
    metadevices youare using). What the error message
    probably is, is that the slice (orpartition) that is
    holding your metadb's is too small.Solaris 8 had a
    recommendation of a couple of megabytes to be setaside
    for metadb's.Solaris 9 recommends at least 25
    megabytes be set aside.So, you may need to increase
    the size of your metadb slice byrepartitioning it
    using format before upgrading to S9. This willinvolve
    recreating all your metadevices.
    ---------------------------------
    There will be special instructions for upgrading when
    Disksuiteis used to mirror your drives. Check out the
    Disksuite docsand/or Solaris 9 Advanced Installation
    Guide at docs.sun.com
    ------------------------------------
    I have done 4 upgrade from Sol 8 2/02 to Sol 9 12/03
    whit DiskSuite 4.2.1 with no problem.But you must
    comment in the /etc/vfstab all disks which are not
    local (EMC,...).To be simple, keep only the minimal
    vfstab (ex :
    /,/usr/var,/export,fd,/proc,swap,...)Normaly, with
    this configuration you don't have any problem
    -----------------------------------
    My experience with upgrading machines from Solaris 2.6
    to Solaris8 which were running disksuite to mirror OS
    slices, as well as provide a bit of Raid5 for a data
    slice: an absolute YES, disksuite must be both
    inactive, uninstalled before you can do an upgrade.I
    suspect the same is true for a solaris9 upgrade from
    solaris8.My experience was, it is very (!!) important
    to have all traces of disksuite gone before doing the
    upgrade, otherwise rather unhappy results can
    transpire (my first attempt, I had to
    restore-from-backup as everything was lost on os
    slices .. partially removed disksuite started
    re-synching content between old and new slices, made a
    real mess).ie, I had to:-capture output from metastat
    so you know how things were configured. Take a copy of
    /etc/vfstab too.-edit /etc/vfstab and remove all
    references to metadisks ; instead use "real"
    (/dev/dsk/c0t0d0s0 ... type) slices.-take a copy of
    /etc/system, then edit the real /etc/system and remove
    all MD related lines, usually clearly flagges as such
    (near the end of the file typically). Comment out all
    non-critical OS slices at the same time (ie, spare
    /data slices, NFS mounts if any,
    etc)-Reboot.-Uninstall all packages relating to
    disksuite. Reboot. Just to be paranoid, pop out the
    mirror disk - it is an "emergency backup" in case
    things go badly with the upgrade-upgrade to solaris9
    on the non-mirrored OS slices-when finished, be sure
    to install disksuite / Solaris Disk manager (whatever
    it is called in sol9)-proceed with "setup from
    scratch" new disksuite config, identical to what you
    had before essentially. Only "tricky" bit, IF you had
    any raid5 be sure to initialize the SWRaid array such
    that it doesn't destroy the contents of the slices
    previously defined :-). A few reboots are required I
    expect for this last step.-finally, you are done.
    Phew. ie, IMHO it is a bit of extra hassle. But ... a
    necessary evil it seems.
