[H-GEN] Network Failover stuff

[Colin]

Hi Michael

You could try the approach that HP-UX uses with MC Service Guard, 
having a base IP address on each interface, and the application IP address
stacked on the active interface.
Or you could obtain a copy of MC/SG for linux. Information is here

All the best

Colin
