AIX

New Question:

The purpose of an alternate disk install is in my opinion to have a ready-to-use-backup and i've read that it is possible to install filesets or software on the cloned disk for testing purposal while the normal system is still running.

The question is: how do you tell AIX (5.2 ML9) to install filesets NOT on the normal rootvg but on the cloned rootvg? And how can you test it?? (off course all this without rebooting...)

thanks!

IBM calls this technique "Alternate Disk Install". You install the OS from your NIM server to a spare disk in the machine. There are tons of docs on this at IBM's website.

However, you can NOT use that disk with the different OS without a reboot. Basically you can have both OS versions installed and choose which you boot to but both can't be running at the same time.

I would like to test a PowerPC emulator and I need some AIX.iso CD image

Does anybody here have this .iso CD image ?

Thread hijack !!
Post your own message please.

pearpc does not claim to even support AIX4.3.3:

"What about AIX? Does it run?
I've got a donated AIX 4.3.3 license and will work at this issue as soon as possible"

AIX 4.3.3 and 5.1 are out of support - no chance of it working with AIX 5.2.
If you want / need a copy of AIX, buy one, it is Licenced, note the comment about having an AIX 4.3.3 LICENCE.

AIX is NOT freeware.

And the one-word-answer is: no way! ;-)

if anybody is going to point out that "no way" are two words I'll throw the whole AIX documentation at his head)

alt_disk_install is good if you want to upgrade a system, but have either very little downtime on your hands or want to be able to switch back very fast in case something fails.

Basically, the (mirrored) rootvg is split into its mirrors and one mirror is mounted in a set of alt_* named directories (usr->alt_usr, etc->alt_etc, etc.). In this alternate hierarchy the updates is made (while running from the unmodified copy) and with a reboot the modified set becomes the default. after testing the new version you can remove the unmodified disk and rebuild the mirror - ready. The user won't notice you working, just the single reboot, is all.

What you want to do is IMHO better accomplished in a micropartition. Create one new partition (via a VIO-Server, you don't even have to have real hardware) and install and test your new version, than either put it into production or not and zap the LPAR (VPAR) you have created - much easier than to twiddle with alt_disk_install, which is not suited for your purpose.

Micro partition, LPAR, don't have that option, no problem, we are talking Alt disk here.

Of course you can, that is half the point (the other being the backup thing).
alt_rootvg_op
Purpose
Performs operations on existing alternate rootvg volume groups.

These power 4 and 5 HMC'd junkies are starting to annoy me now... you don't need a 10k box to doo half the stuff you people think you need to create an lpar / micro partition for.

Alt disk install your new instance on a spare disk and customise / add fixes - software with the alt_rootvg_op command. Of course you will need to actually boot it to test if it all worked - best done at the weekend for the user satisfaction, oh, and the overtime ;-)
