    Ronald> You mean, if you have an initialized fabric, opensm can't work?

No, just that OpenSM has to be able to handle an uninitialized fabric,
since the SM is responsible for initializing the fabric.  However the
SM should work no matter what state the fabric is in.

The IB spec is probably the best reference for what the SM does.
Volume 1 Chapter 14 has a very thorough description of subnet management.
