One can run 2 OpenSMs on different CA/ports on a single machine. The
main things in doing this is setting them up to use different
directories. This is accomplished via setting OSM_CACHE_DIR. You will
want to configure dump_files_dir and log_file to be different. Also, you
will likely want different subnet_prefix configured in each subnet
(opensm.opts). There may be other configuration files different as well
based on what your requirements are.

Hope this helps.

As to how to do this with opensmd, I'm not sure as I don't work with
that. When you figure this out, it would be useful if you posted the
information. Thanks.
