If you have multiple machines set up in an HACMP cluster, is there any value
to attempting IP aliasing on a single nic rather than having multiple nics
available to cover the IP addresses of every machine that might fail over?
Take for example a 3-machine cluster, where A and B could possibly both have
to fail over to machine C. I suppose there could be possible performance
improvements from having three nics in machine C, but is it necessary?
So, what happens if machine A is failed over to C and machine C's single nic
was aliased to machine A's address. If a client attempts a connection (be
it telnet or whatever) to machine A, what happens? Which source address do
the return packets have?
