Nice post! I didn't know about the media library from the VIOs and I was planning a little trip to my datacenter to put the cds into a real dvd-drive. Now, I'm gonna be able to avoid that! <div>&nbsp;</div> Happy to hear that the upgrade to AIX 7.1 went smoothly. I'm planning one of my NIM server this week and I will definitely use this procedure! <div>&nbsp;</div> Frank.

I use the Virtual media library all the time. It's quick to master and easy to use. One limitation is that it will only serve the clients on the same managed system as the VIO server (unlike NIM). But in these days of multiple LPARs on a single physical server, it's not such a problem. Good luck with it all.

The only thing I was wondering about.. is that with NIM, you can do a lot of customization (post_install script, network assignment, etc.) when duplicating partitions, which I don't think you can do when you build a partition through an ISO file of a mksysb shared through VIO. Or maybe I'm missing something. <div>&nbsp;</div> Your post made me realize that if I can do some customization, my weekly DR rebuilds that I do through NIM now, I could move all of that off to this solution and save hours when restoring all those production mksysbs! <div>&nbsp;</div> Frank.

Yes, you're right. NIM does allow you to tailor those things. I usually build a SOE LPAR with plenty of the standard customisations and then I do the network settings after the LPAR is up and running. NIM requires you to do it before via the SMS menus. <div>&nbsp;</div> Of course if you recover devices on your bosinst menus when you do a mksysb restore, you get all your network settings as well. But generally you'd only use that to rebuild the same LPAR onto the same server, not to clone to a new LPAR.

It's a very good post for another method of upgrading AIX! Well, this method of upgrading does not give an easy way to back out if anything went wrong. I would suggest to use more reliable alt_disk_install to upgrade AIX on any business critical servers.
