IBM Redbooks | NIM from A to Z in AIX 5L
NIM does not require all to be on the same subnet. We use one nim master for hundreds of AIX boxes on many subnets. Exactly how I'm not sure, but it definately can be done.
You can definately use NIM to do a bare-metal install of a new server. If you had a hard drive crash you'd replace the drive and install the OS using the same procedures. Then once you have an OS on there you could restore your mksysb to get all the details the same as previously. I'm not sure if you can go directly from the mksysb skipping the initial OS load step or not, but I'm sure the redbook would have that info.

You take the MKSYSB on the client storing the result on the NIM server in for example /export/backup.
You then define the MKSYSB as a NIM resource.
You then allocate the resource to the NIM client to be re-built.
When the crash happens rootvg is replaced on the client and a boot to SMS will occur as there is no O/S. Setup the bootp section of SMS; declare the IP address of the client and the IP address of the NIM server as the server; also declare any gateway address to get round subnet differences. You could try a ping test just to make sure. If all is correct set the client in bootp mode and the system restore will start.
Hope that helps.

Friend's,
I was playing around with NIM in my environment & had a quick question in mind which I didn't/couldn't find answer to, which is -- how to find the name of the NIM server sitting on the NIM client?
All leads to the answer would be much appreciated, many thanks!
