AIX

I would guess that your running ip tagging on your sea adapters. Which would mean when you setup your new lpar you would have to give it the correct vlan number for the vlan you addressed it in. On your lpar look at its properties then virtual adapters then your ethernet adapter...you should have a vlan number in there for "VLAN ID" and that vlan id number must be the correct one to match to one of the supported vlans ( which is a network ) on your SEA adapter on the vio. The vlan ID you use must be listed on the vio servers sea adapter properties and the vlan ID must correspond to the ip address you gave the server ( be in that subnet ).

Hi, PPPP

1. make sure lpar AIX_SA vlan id same as AIX_CSS on HMC.
2. try to down detach ent0 on lpar AIX_CSS (if you are able to do so)

Code:

ifconfig en0 down detach

and lpar AIX_SA

Code:

ifconfig en1 down detach

3. start the tcp/ip for AIX_SA first and then for AIX_CSS.

I rephrased my former post from last night and added some info. Hopefully it is more helpful than before.

Hey guys, thanks for all the responses

As I was reading through the post, going through the settings, I found a discrepancy between my non-working LPAR & the working one:

Under Hardware Information -> Virtual I/O Adapters -> Ethernet, on my non-working one (AIX_SA) it shows this:

On the working one (AIX_CSS), it shows this:

Notice the "Virtual Adapter" field for AIX_SA is empty. Could this be the reason why it's not working? How do I fix this?

Thanks!

That's exactly it. It is all on VLAN 1.


Thanks for the link! It goes through how to configure a SEA and how to hook things up properly. But how do I check if my current configuration is correct?

This could be another cause of my problem. The working LPAR is on a different subnet comparing to the non-working one. Forgive me for being an amateur but do they have to be on the same subnet? The VIO's SEA is on the same subnet as the working one. Do I need to create another SEA if my LPAR is on a different subnet?

Here's an update.

I tried to use DHCP and it worked! Then I reconfigured it back to use static IP and it stopped working again. After a while, it just started working I don't have time to figure out what I did to fix it at at this point but will check back later..

Thanks for all the help

Sounds strange If you find out more, keep us updated please, thanks.

You may want to check your LHEA settings from the HMC. A couple of intern's at my last posting had similar issues and majority of time LHEA's were not set right. you may also want to check your loop back to make sure that your TCP/IP protocols are working correctly.
