Upgrading to 2.6 with DiskSuite?

Summary:
Most people stated that they were able to upgrade without any problems
whatsoever. Meta-devices did not have to be reconfigured. However, it is
necessary to comment out the Disksuite meta-devices prior to upgrade, and
to uncomment them afterwards (Ref: Solaris Advanced Installation Guide
2.6 P.26). It is highly recommended to do an initial install instead, as
the 2.6 filesystem has many new features and requires a newfs.

It is highly recommended in the Solaris documentation to NOT do
an upgrade, do initial install instead. The filesystem for Solaris 2.6
is new&improved. You will only get it's capabilities by running a newfs.
At least for the filesystems that get upgraded.

We upgraded without any problems. No reconfiguration necessary.
Yes. We never even had to touch disk suite. I think we did
have to comment out the disk suite disks in /etc/vfstab to
get it to go though. After the upgrade, just uncomment them.
Matthew Stier <Matthew.Stier@tddny.fujitsu.com> stated:
It is my understanding that to do an upgrade with DiskSuite, you basically need
to remove it, and re-install it after the upgrade.
Note: If you take care and do not disrupt the components of metadevices, (except
for the OS partitons of course) you can rebuild the metadevices after the
OS upgrade and reloading/initializing of DiskSuite.
Note: The above note only applies to RAID 0, 1, and 0+1 devices only. Raid 5
devices are re-init everytime they are recreated.

Please notice that before upgrade , you MUST comment out metadevices
entries (/dev/md) from /etc/vfstab. (which means that metadevices CANNOT
be upgraed) Ref: Solaris Advanced Installation Guide 2.6 P.26.
