My Nim Server and Client reside on different subnets. When I try to install my VIOS server thru NIM, it results in a error 0608.

There are two network resources configure in NIM, and the system are networked as follows:

NIM server
IP 192.168.0.15
Network IP 192.168.0.0
Gateway 192.168.0.1
Subnet mask 255.255.255.0
NIM Client
IP 192.168.2.20
Network IP 192.168.2.0
Gateway 192.168.2.1
Subnet mask 255.255.255.0
SMS
1. Client IP Address http://192.168.2.20
2. Server IP Address http://192.168.0.15
3. Gateway IP Address http://192.168.2.1
4. Subnet Mask http://255.255.255.000

The Ping test is successful, and I start the VIOS install, which stops which a code 0608 shortly after the Welcome to AIX screen is displayed on SMS.

The NIM server is a Power5 p550, AIX 6.1 TL6 SP6
Client is a Power7 p770

Do I have the basic networking and gateways set properly?
The NIM client is new hardware, on new network gear, and the only system on that network segment currently. I din't know if it is my NIM config, or if I should question teh network gear, as it new and I am the first system on it.

Have you tried netmask 255.255.0.0?

For ARP and TFTP to work the client and server have to be in the same sub-network.

Happen to have this exact issue today while cloning a mksysb image :)
What does your /etc/bootptab look like? modify it such that it has the nim server's address as gw.

After messing about for a day, we put the NIM server and client onto the same switch, and did the install.

I have the NIM server and client working fine across subnets in another environment, and duplicated the setup - Network admin thinks there is something going on between VLANS on the network

the last comment I think is the most correct, you probably have some restriction on the lan switch, happened to me exactly the same, the ping worked like tftp, my configuration was correct but the network administrator had restricted certain features, to remove worked without problems.

I faced this almost 4years back on a client to install aix , ping success-means tcp-active on switch , but i remember udp to be allowed to push the file thru tftp - worth checking .
