In first run OpenSM will not fetch existing LFTs from the switch and will setup this from "scratch". I think that the reason for delay should be different. Also it is single-switch subnet, its setup should be reasonably fast in both cases. Do you see any errors in OpenSM log file? > my another question, should the HCA that opensm resides on be physically > connected to switch port 0? No. Port 0 is switch's management port and normally it doesn't have physical connection.
