Ok, that means eth0 (192.168.128.X) is the private network (which communicates with all Manage systems).

Eth1 is your public IP (which you use to establish connection from putty or web).
Unless you do VLAN Tagging or give a dedicated ethernet card to LPAR, they have to be on same subnet as your VIO

Code:

"Now I figured that default gateway has to be the same one that of VIOS  and LPAR's are using in order for HMC to connect to them via console".

This sentence is not really true, because the connection to Manage systems is through Private network and that is the reason you see Manage systems with different subnets are connected to HMC. (my personal example, I have my HMC on 10.10.4.x network and my MS on 4.x and 170.x)

Ok, if your eth2 configuration worked, then something must be wrong with eth1 configuration (either gateway or subnet mask values), or may be that IP is conflicting with other host.
We need more details on this to understand and troubleshoot.

Once you are in HMC, you will use console to get into VIO/LPAR, but in order to reach HMC you configure Public IP (in your case eth2).

So, once you are connected to HMC, then you use console to get to VIOS/LPAR.

Look at the network topology (from HMC under HMC management select that), you should see eth0 as the interface for all connections.

Hope this helps.
