Clone???

Hi. Assuming you have a fairly recent version of AIX, it's pretty straightforward and there are only a few things to consider.
If the platforms are fairly similar (both are uni-processor or SMP, rspc or chrp, etc..), then all you need to do is make a mksysb backup, ipl and restore the backup.
If the plaftforms are fairly different (one is a uni, the other smp or one is rspc and the other is chrp) then IBM has a VERY neat trick. Make your mksysb as before (and put it in the tape drive of the new system), but when you get ready to restore it place an O/S installation CD -with the same oslevel- as the mksysb in the CDROM, ipl the -CD- and during the install choose restore from system backup. Both the tape and CDROM will be used as needed for any fileset changes that might be needed.
I hope this helps. Let us know how it goes.

hi
Cloning on AIX have very vast meanings.You can clone your current running rootvg
to another free disk(smit alt_clone ) within same machine.You can restore mksysb
of one machine to another machine(even diff architacture or diff o/s level; but deffinetly you require AIX installation CD along with mksysb tape for this purpose so that missing or latest filesets can be installed automatically)
So cloning one RS6000 machine(source machine) require just its mksysb restoration
to one or more target RS6000 machines.
you can also customize your cloning process..see Aix4.3 installation manual for
more detail.
NIM mksysb installation also support cloning.

Also,
If you want to clone the ENTIRE system (i.e. All VG's) It requires multiple steps. The previoulsly mentioned mksysb for rootvg and 'savevg' for the other VG's. A separate utility called sysback will handle it all for you at once. I sat in on a demo of version 5 and it is slick. You can even move LV's between VG's on restore.
