I'd do it by lv.
Do a 'mklvcopy 3 lvname hdisk_name'. One of the nicer features of lvm, you can make 3 copies. Once you get stuff all moved the way you want it, do a 'rmlvcopy lvname 2 hdisk_name'.

Subject: Re: Urgent!! rootvg over 2 disks? [Virus checked]
The way to get around that is to add all of your disks to the vg, move all of the LV's to the disk you want them on (hdisk0 and hdisk1), then run the following:
mirrorvg rootvg hdisk2 hdisk3
This forces AIX to only put the copies on the two disks specified and not do anything crazy when you setup the mirror.
When you want to unmirror you use
umirrorvg rootvg hdisk2 hdisk3

i think you can...you just put all 4 disks in the vg. however, do NOT
expect it to look like that. what really happens is you say "copies 2"
and "each copy on seperate physical disk" and set a stripesize....the
lvm basically throws stuff at the disk. I never figured out a way to
map it the way you said. the end result is the same, in terms of space
use and data protection, but if you lose a drive, it gets complicated....
