AIX network installation...

I'm researching ways to do network installation for AIX server. What is the best utility out there that works best for AIX network install. So far, I found using Linux server wtih Virtual I/O Server (need VIOS disk) or Network Installation Management (NIM)? Are there other methods?
 
I had used VIO server for installing AIX on virtual machines.

I did a second copy of a LV (on VIO server) being used for AIX OS of some virtual system - after that I did splitlvcopy (possible but not recommended on open LV - so better is to stop for a while system having AIX running on that LV) and used that splitted copy for the other/new system.


you can also use "dd" but also recommended to stop "source" AIX system for that moment

# ls -al /dev/*vdisk1
crw-rw---- 1 root staff 36, 2 Oct 18 15:31 /dev/rvdisk1
brw-rw---- 1 root staff 36, 2 Oct 18 15:31 /dev/vdisk1

# dd if=/dev/rvdisk1 of=/dev/rvdisk1clone bs=8M


The same you can do if you are using whole disks on VIO server for VIO client's OS.

On standalone systems I did the following trick to have system installed quick:

on my P55A I inserted a disk from new machine, created third LV copies of rootvg's LV (mirrorvg -m -c 3 rootvg thedisk). Having quorum off (standard in mirrored rootvg) I got the disk with third copy and place it in new system. After that I had to remove from ODM all no longer accessible disks on both systems (missing disks). Thats all.

I strongly recommend to change rmc resource id on cloned host running the command after it is stated first time: /usr/sbin/rsct/install/bin/recfgct


 
While mirror-cloning a rootvg like this and then splitting off a mirror via VIO server operations is a way to "install/duplicate" a new VIO client machine, it is IMHO not an IBM supported procedure.

That being said, I've been told that some test/porting labs do similar operations to recreate a number of test environments from a "known good" source AIX rootvg...
