[ofa-general] OpenSM in WAN ring.

[Steven Carter]

The OpenSM man page says that Up/Down routing should be used for 
networks with loops.  We have three WAN sites linked with a combination 
of Obsidian and Bay IB WAN devices in a ring with an instance of OpenSM 
running at each site.  Although I don't think we've seen any ill affects 
of not using Up/Dn routing, I assume that I should dutifully obey the 
man page.  I intend to run OpenSM with the options '-x -R updn -a' at 
each site, then synchronize guid2lid and opensm.opts.  Does this sound 
like the correct course of action or am I missing something?

Thanks,

Steven.
