any idea when this stuff will get done?
another question: If one brings back the old path (after the first 
failure) and use the old path record
to do lap/apr then reenabling migration using LAP/APR should work, right?

next question is: which component is suppossed to change QP state to 
REARM? spec just says:
"based on a command from a management entity, the QP state is set to 
REARM" .

does the current CM code do it automatically? In my case, its not 
happening...

thanks, som.
