"Failover Only" or "Failover/Failback"

I'm using EVA4000 and two rx2620 servers (HP-UX V2).
I have two HSV200 controllers and also Dual channel FC cards on each rx2620.
I'v installed secure path v3 and I'v defined the preferred paths.
In command view there are some options for Preferred path/mode .
Failover Only and also Failover/Failback.
So wich one is suitable for the mentioned environment ?
As I read HP-UX only supports "Failover only" mode.
