Iam attempting to add a client to NIM however the new client has a different subnet than master 10... & 193... , I've established from redbooks that it should be possible but can't find anything that states how?
Does anyone use nim in this way?
smitty nim --> perform administrative tasks --> Manage network --> define a network (ent)
Define a Network
Type or select values in entry fields.
Press Enter AFTER making all desired changes.
[Entry Fields]
* Network Name [Net_193_X]
* Network Type ent
* Ethernet Type Standard +
* Network IP Address [xx.xx.xx.0]
* Subnetmask [xxx.xxx.xxx.xxx]
Default Gateway for this Network []
Other Network Type +
Comments [193 Network]
You have to define the Network IP address (say you have 10.10.193.xxx) then you will mention 10.10.193.0 (remember the zero)
Also ask your network team what is the subnet mask and enter it there and hit enter.
You can run lsnim -c networks to view the defined network.
Also run lsnim -l Net_193_X, to check the Network address and subnet mask.
You will 1st do an entry on new hosts in /etc/hosts file of nim server (IP and Hostname) and when you define a new machine (you will see the NIM network as Net_193_X)
Now the tricky part,
In the SMS menu of the client under "Gateway IP Address" you will mention the Gateway of client (193.X) and NOT NIM server gateway.

Reason: Added another code
Ok, first of all I need to know the 'IP, gateway address & subnet mask of NIM and client (of 193 network).
If you are restoring mksysb on new client using NIM, you use SMS menu to configure the IP's
Giving an example of my environment
Code:
Under the Main menu,
select option no 2. Setup remote IPL (Initial program Load)
Select the network adapter
Select IPv4, then BOOTP, then IP Parameters
IP Parameters
Interpartition Logical LAN: U9117.MMD.104F3F7-V15-C4-T1
1. Client IP Address [10.10.170.250] --> My client IP
2. Server IP Address [10.10.4.140] --> My NIM IP
3. Gateway IP Address [10.10.170.1] --> Client Default G/W
4. Subnet Mask [255.255.255.0] --> Client Subnet mask
press esc (escape), and select option 3. Ping test
The ping test should be successful.
The above is for new clients
If you are saying you already have some client existing on 193 network, then you gotta define the network on NIM server 1st, and on client run the below
Code:
niminit -a master=<nimserver name> -a name=<clientname>
then run
smitty nim_config_services --> Communication Protocol used by client --> nimsh
Hit enter and try to connect from NIM, it should work.
Hope this helps.

Reason: Example
"Under the hood" NIM is a common bootp-server, if used to boot clients (like in an mksysb install). To work across network boundaries you need to make sure your router(s) is/are configured as a "bootp relay agent", otherwise bootp-broadcasts would be dropped. See RFC 1542 for details.

Hi Guys,
I'm building a new NIM environment with clients on 3 different subnets. I want to get some advise on what is the best approach for this kind of setup.
This is the sample network for my new NIM.
Master IP: 10.20.1.20
Client IP subnet_1: 10.20.1.21
Client IP subnet_1: 10.30.1.21... (5 Replies)
hi Admins,
How can I check the NIM master hostname/IP name from NIM client ? I don't see any option that I can try with nimclient command.
Let me know..
Thanks, (5 Replies)
Hi.
I change my client's IP and hostname but I forgot to change anything on the master. How can I redefine or modify my client's resource from my master, or with using smit niminit from my client ?
