Can you just use dm multipath for this? You would have a dm device with 2 paths. One to each target. You would then logout the session you do not want and dm multipath would switch to using the one you want. > > How: I've used tcpkill to terminate the tcp connecting, in order > to*trigger the recovery mechanism*.

However, if you do a STOP_CONN_TERM call it is going to release some kernel resources you might not want to release if you plan on using the session again. Also it might create leaks and kernel oopses depending on what you do with it later. > > Is this a *BUG* or *by-design*?
