We have one NIM Servr which has two different NIM Interface. Primary NIM interface is 172.x.x.3 and secondery interface is 192.168.255.1. First one serves all the 172 address' and 2nd one serves 192.168.255 address. It worked nicely till we got our P6 and P7 Servers. Whenever we try to load P6/P6 lpars using 192.168.255 interface it shows
client
TFTPBOOT

---

Server IP ....................172.x.x.3
Client IP ....................192.168.255.2
Gateway IP....................192.168.255.1
SUBNET IP ....................255.255.255.0
(1) Filename ................/tftpboot/p6_550a_lp01
TFTP Retries ...............5
Block Size.........512
1
2
3

And then it fails. If I use the use the same IPs to load P5 Lpar it works perfectly. Now the same setting works for P4/P5 Servers. But something did change with P6/P7 Servers. I don't know how it gets 172.x.x.x address. I checked the info file and it is pointing to 172.x.x.x address but works for P5 Servers. Can any one please help.

Any idea.

Hmm,
if you have a NIM Server with 2 Nic's, then you have 2 Networks for install
How are the new p6/p7 Servers defined?
Why are they requesting the wrong IP?
Is the 192.net the Install Net?

To install a new machine you can do the following:

• open HMC GUI via Webbrowser
• change profile to boot to SMS
• open console for the lpar you want to install
• boot into SMS
• define your NIM Environment manually (look in NIM Guide from IBM Redbooks)

- Look for the right Ethernet Adapter connected to your NIM Server
- define NIM-Server IP
- define NIM Client IP
- define Protocol Settings
- check with ping test, if the NIM Server is reachable

• exit SMS

look machine installing

Cheers,

Thanks for your reply but the problem is not as simple as it looks at the first place. What you told actually the basic nim load procedure.
Here is the setup which I build 3-4 years ago to use multiple NIC to suport multiple subnets and multiple customers without using any gateway and to load more clients simultaneously. Our current configuration is as below. Last two interface interface doesn't work for p6/p7 servers. I recently upgraded the OS to AIX7

Here is the original configuration

root@srikrishna-lsnim -c networks
SRIKRISHNA_MASTER networks ent
192_net networks ent
SID_NET networks ent

root@srikrishna-lsnim -l 192_net
192_net:
class = networks
type = ent
Nstate = ready for use
prev_state = ready for use
net_addr = 192.168.192.0
snm = 255.255.255.0
routing1 = default 192.168.192.1
root@srikrishna-lsnim -l SRIKRISHNA_MASTER
SRIKRISHNA_MASTER:
class = networks
type = ent
Nstate = ready for use
prev_state = ready for use
net_addr = 172.21.64.0
snm = 255.255.252.0
routing1 = default 172.21.64.1
root@srikrishna-lsnim -l SID_NET
SID_NET:
class = networks
type = ent
Nstate = ready for use
prev_state = information is missing from this object's definition
net_addr = 192.168.255.0
snm = 255.255.255.0
routing1 = default 192.168.255.1

This is working configuration for P4 & P5 Servers for couple of years. I changed the above setting like this and same issue.

One of the experimental configuration

root@srikrishna-lsnim -l SRIKRISHNA_MASTER
SRIKRISHNA_MASTER:
class = networks
type = ent
Nstate = ready for use
prev_state = ready for use
net_addr = 172.21.64.0
snm = 255.255.252.0
routing1 = default 172.21.64.1
routing2 = SID_NET 192.168.255.1

root@srikrishna-lsnim -l SID_NET
SID_NET:
class = networks
type = ent
Nstate = ready for use
prev_state = information is missing from this object's definition
net_addr = 192.168.255.0
snm = 255.255.255.0
routing1 = SRIKRISHNA_MASTER 192.168.255.1

Still no luck with P6/P7 Servers. But all the settings are working perfectly for P4/P5 servers. I tried all combination of the routing information but nothing worked so far.
