The perfect occasion to live upgrade

I'm a big fan of Solaris Live Upgrade. I regularly live upgrade new Solaris Nevada builds onto my company's Acer Ferrari 4000 laptop and it's just sooo convenient.

But there are so many customers and other Solaris users out there who still haven't tried live upgrading yet. You know, you're buried in work and you never quite had the time to try it out or read the manual or you simply don't know that it exists etc.

Today, I visited my old university's computing center, the Clausthal University Compute Center and did a Solaris workshop for the campus admins there. What better place and time is there to do a live upgrade than actually doing it while you present?

So this morning we started the Solaris workshop by introducing the three flavours of Solaris: OpenSolaris, the development project; Solaris Express, it's 2-weekly binary release and Solaris 10 the current production release. Since everybody attending the workshop will want to upgrade a Solaris machine sooner or later, why not do it now?

The first golden rule of live upgrading is: Install the new release's live upgrade packages. I had Nevada build 59 with me, so a few pkgadd(1M)s later, that was done. Then lucreate(1M) started it's job of copying my current boot environment into a free slice on my laptop's disk, while I continued with our workshop.

We covered some basics on Solaris 10 and four in-depth segments about SMF, DTrace, ZFS and Zones (and Containers). About halfway through our workshop, lucreate was finished and so we started luupgrade(1M) with a loopback mounted image of the Nevada 59 DVD. Just after we finished our workshop (4 hours total), live upgrade was finished as well and we all gathered around my laptop, watching it reboot into a freshly upgraded Nevada build 59 boot environment :).

Solaris Live Upgrade is one of those things that you postpone for so long, then you finally try it and after you've done it once, you can't imagine living without it. I hope you've become curious now, just like my workshop attendees today, and that you'll soon try it out as well. Of course if it isn't already a part of your everyday life as it should be...

P.S.: Now I'm sitting in my friend Ingo's house and he has this notebook that his wife's granddad gave her and his friend Yi is coming by tonight and guess what we'll do next: Install Solaris Nevada onto that notebook. It's a Medion MD6100 and I've already found the corresponding driver CD with the missing SIS900 network driver on the net so installation should be quite easy...

Hi, I have an open call about LU. Sun france has reproduced my problem: if /opt resides in a SVM soft partition, then he will be not copied to new BE.

Hi Alain, sorry to hear that LU didn't work for you. Have you checked the -m option of lucreate in detail? It allows for multiple paths to be mapped differently to their LU targets. See: http://docs.sun.com/app/docs/doc/816-5166/6mbb1kq79?q=lucreate&a=view I hope Sun Service can resolve your problem quickly. Best regards, Constantin

Yes i have read details about -m option and i use it. I hope LU will work for me after Sun will have solved this issue. I plan to use LU to upgrade or patch my servers: at my work, patches are the first culprit when something go wrong, even if i haven't applied patches at all ! With LU, it's very easy to go back. Just another remark: to use LU on S10 march 2005 i was forced to reboot first to apply patches. Without these, LU don't start.
