You did it in response to Brian's request (which I apparently never quite 
understood), see [1] below.

See also my later email in this thread (one or two days back) which discusses a) 
- f) options about what happens in various cases (multisource on/off, 
reseg/resel/srv-error).

 From Andy:
Hi Matevz,

Unfortunately, you misunderstood. The tried= has no effect on the static 
redirect. In fact, it shouldn't have for the error recovery case. For a 
reselection, I see Brian's point that, by default, you want to stay in your 
local cluster. Now I have to find a way of allowing to say you want to reselect 
irrespective of location.

Sorry, I don't quite understand. They have static redirect on the local fnal
redirector? I thought this does not fire when tried= is specified, only for new
/ initial file opens (at least that's how I understood Andy).
