It took me too long to find the term I was looking for - kept thinking multi-boot (which is for something else!).
I think what you might be looking for is multibos. The trouble is going to continue to be that /backup is in rootvg and I do not know if it will be available on a second boot (with the multibos)
In short, what multibos does is copy the current rootvg (key) logical volumes - giving them different names (much like alt_disk_install does, but now within the current volume group).
Assumming /backup (since it is not a default rootvg logical volume) will be available after a reboot to the "other" rootvg you could attempt, assuming the sum of the current PP sizes are less than 10G:
For more on multibos look at two articles on IBM Systems Magazine: AIX-Updates-With-Multibos/ and Working with Multibos
However, I would also consider using the information above from ka00na and zxmaus to "almost" use mirrorvg - by just adding the key AIX partitions
to the 10G disk, backup and remove /backup; then remove the copies on original disk; and restore /backup - roughly this:

Guys can anyone tell how can we do faster disk cloning
Below i found in google
1. dd if=/dev/sda of=/dev/sdb bs=4096 conv=noerror,sync
So adding "conv=noerror,sync " makes it faster looks against not adding it
2. Enable write cache activated (hdparm -W1 /dev/sda) then run dd ..

Hi,
I'm looking to copy a boot disk on an old Solaris 8 system using dd. I'll bring the system down to single user mode and begin from there. I'm copying my source disk to a larger target disk. Do I need to do anything other than the 'dd' command below because the target disk is bigger? ... (2 Replies)
