Hi,

I am planning an upgrade of my U2 to the latest Solaris 9 version (0/04)
and I have a fairly simple question: the system is mirrored (two disks)
using SVM (don't know the version, but the current OS version on that
system is Solaris 9 01/04). Is there anything special that I need to do
before (or after) upgrading (like breaking the mirror) for the upgrade to
work? Or would the installation process do everything by itself?

TIA, Dragan

Solaris 9 should be happy to upgrade with no intervention to SVM (such
as breaking mirrors) at all.

That's the first thing I tried when I got my paws on the first
pre-release Solaris 9 with SVM integrated - I set up a mirrored swap
and root configuration on Solaris 8/DiskSuite 4.2.1 and upgraded to
Solaris 9. I was very pleasantly surprised with the results.

Of course the usual caveats apply; YMMV, always take a backup first.

Excellent. Great to know that. Thanks Tony.

I hope I would be too. Well, I have a long weekend in front of me (Civic
Holiday in Canada), so even if it breaks, I can rebuild the system.

Of course. The second mirror is the backup :-)

Just joking, of course.

Bye, Dragan
