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.
