Oh, I'd say that chatter is still necessary.
But what you do is define two different TCPIP VSWITCH controllers, on
(by definition) different physical OSA ports, with different cables
connecting them to the switch(es, ideally).
Eh? What "by definition"? Define two controllers and don't worry
about
it any more. Just make sure that you have automation watching for
Controller Death and restart it ASAP. The two controllers will
provide
the needed controller redundancy for any and all VSWITCHes you create.
Am I confused? I thought the VSWITCH controller required a dedicated
OSA port.
I guess it doesn't have to be a different physical port, but wouldn't
that be wise in case you lose a port or a cable? Ideally, ports on
entirely different cards, going to different physical switches, right?
Then, if those switches are trunked, no need for host-level VIPA, in
that incoming packets will still be able to get to the host no matter
which physical switch they're hanging off of. If they aren't,
though, you *do* need host-level VIPA providing dummy addresses so
that packets can get down the right wire to the right VSWITCH to the
right guest.
