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?

AIX network installation...

VIO server is used fot hardware virtualization for LPARs ond not for network install.
For NIM usage have a first look to:

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...
