That is certainly a problem, indeed. I'm waiting for the DFS tests to
finish and then send a series that contains a potential fix for that --
e.g. not sharing TCP servers when mounting DFS shares. We used to not
share tcons with DFS mounts because they might contain different prefix
paths but connected to same share, however that wasn't enough because
multiple DFS mounts may connect to same target servers, although they
might failover to completely different servers.

That's a interesting question. I recall discussing this with Aurelien
some time ago while running a few DFS + multichannel tests.
So yes, I agree with you that when we successfully reconnect to failover
target (primary channel), then we should also update all secondary
channels with the new server's ip address and reconnect them.
