Thank you very much for the quick reply!

Right, that sounds like what we want. Could you by any chance point me in the
right direction of how I do that, please? (A link to an example documentation
would be wonderful!) And just to clarify, in this configuration, I will still
be able to fail over from one cluster to the other?

Great, thanks! Now I just have to figure out how to do it... Any guidance
would be much appreciated! I have so far managed to install the Sun Cluster
Geographic edition on both machines. For now I installed the quorum server on
one of the machines, too though in service we would put the quorum server on a
third site (as we do with our heartbeat v2 setup at the moment). But I haven't
gotten anywhere with configuring them as all commands seems to need to be
pointed at shared storage for storing their state and the whole point of our
set up is that there is no shared storage anywhere in the system.
Thanks a lot in advance for any further help you can give me!
Best regards,
Anton
