Hi guys,
            Thanks to all of you who helped me get this sorted.   It's all up 
and running very nicely now with multiple OSAs for redunancy etc and 
hipersockets.

Lutz, Thanks for the clarifications.
Chris, Thanks for the redpaper, it was much clearer, but perhaps that was 
because I had a glimmer of what I was trying to do by that time.


 It's all quite trivial once you have a clear picture of what you are trying to 
do.

For those interested it's quite simple.
Define VSWITCHs and point them at real OSA triplets, not the one used by TCPIP.

CP DEFINE VSWITCH VSWITCH1 RDEV 88B 
CP DEFINE VSWITCH VSWITCH2 RDEV 72B 
CP SET VSWITCH VSWITCH1 GRANT LINUXVM1  
CP SET VSWITCH VSWITCH2 GRANT LINUXVM1  

These get picked up by different switch machines to give additional redundancy.
q vswitch all

In the directory for LINUXVM1 -

NICDEF 0710 TYPE QDIO LAN SYSTEM VSWITCH1  
NICDEF 0870 TYPE QDIO LAN SYSTEM VSWITCH2  

Where 710 and 870 are where the linux machine expects its OSA cards to be.

For hipersockets, just dedicate 3 OSA ports, from the hipersocket channel.
DEDICATE F000 F000  
DEDICATE F001 F001  
DEDICATE F002 F002  

All works a treat once you can imagine how it hangs together.

Talk about making something simple sound complicated. :)

Thanks again,

Ron.
