This can be a tough concept to grasp - I'll list the steps I do.

1. Edit VIO profile from the HMC like you list in #2.
- I noticed that the steps you listed in #2 go into the 'Dynamic Logical Partitioning' but be careful because if you don't make changes to the profile also then when you reboot the lpar (VIO or client) all changes will be lost.
- Make sure you put a checkmark in 'Access external network Trunk priority'. Also , make note of which adapter ID you give it (it doesn't matter what the number is, this will be used later when you do the mkvdev command). I used 23 because we have a .23.xxx network segment and a .41.xxx segment (you can guess what I used for the other virtual ethernet adapter id).

2. Edit the lpar client's profile from the HMC and do all of the steps you listed under #2
- BUT do NOT put a checkmark in 'Access external network'
- Use the same Adapter ID you made note of in my Step 1. I also use the same ID for the VLAN ID.

3. Create the SEA on VIO1 - (on our system the 23 segment cable is plugged into ent1)
Example from my VIO1:
# lsdev -Cc adapter |grep ent

ent0 Available 02-08 10/100/1000 Base-TX PCI-X Adapter (14106902)
ent1 Available 0A-00 10/100/1000 Base-TX PCI-Express Adapter (14104003)
ent2 Available 0A-01 10/100/1000 Base-TX PCI-Express Adapter (14104003)
ent3 Available 08-08 2-Port 10/100/1000 Base-TX PCI-X Adapter (14108902)
ent4 Available 08-09 2-Port 10/100/1000 Base-TX PCI-X Adapter (14108902)
ent5 Available Virtual I/O Ethernet Adapter (l-lan)
ent6 Available Virtual I/O Ethernet Adapter (l-lan)

## Find 23 segment (C23) virtual adapter (Ex. ent5)
# lscfg | grep ent | grep Virtual
* ent5 U9117.MMA.10FF11F-V3-C23-T1 Virtual I/O Ethernet Adapter (l-lan)
* ent6 U9117.MMA.10FF11F-V3-C41-T1 Virtual I/O Ethernet Adapter (l-lan)

## So we will create the SEA using ent1 as the physical adapter and ent5 as the virtual adapter
$ mkvdev -sea ent1 -vadapter ent5 -default ent5 -defaultid 23

4. Boot the client lpar or run cfgmgr if it's already up and running - then configure the adapter as usual with 'smitty tcpip'

Hope this helps.

NAME

       roar_vs_connection_obj, roar_vs_stream_obj, roar_vs_vio_obj - VS API interface for use of main API

SYNOPSIS

       #include <roaraudio.h>

       struct roar_connection * roar_vs_connection_obj(roar_vs_t * vss, int * error);

       struct roar_stream     * roar_vs_stream_obj    (roar_vs_t * vss, int * error);

       struct roar_vio_calls  * roar_vs_vio_obj       (roar_vs_t * vss, int * error);

DESCRIPTION

       Those  functions  return  internal  connection, stream and VIO object of the VS object.	They are used to use the main API with a VS opened
       stream.

       roar_vs_connection_obj() returns the connection object used for the control connection to the server.

       roar_vs_stream_obj() returns the stream object storing information about the stream.

       roar_vs_vio_obj() returns the VIO object used to read data from or send data to the server.

       Returned objects are freed as soon as the VS object is closed. If the VS object was created using roar_vs_new_from_con(3) the connection is
       not closed by the VS object and stay valid after close until it is closed by the program or library.

       The VIO object MUST NOT be used while in buffered mode.

PARAMETERS

       vss    The VS object to return internal objects from.

       error  This  is	a pointer to a integer used to store the error value in case of error.	This can be NULL if not used but it is very recom-
	      mended to use this error value to report good error messages to the user.

RETURN VALUE

       On success these calls return the described object.  On error, NULL is returned.
