Which driver are you using (VAPI or OFED)?

I hope that the following info will be useful:

in OFED:
ibv_devinfo can give you the available HCAs in you host
in C: ib_register_client will call your handler for every IB device in host

in VAPI:
vstat can give you the available HCAs in you host
in C: EVAPI_list_hcas can give you the available HCA?s

thanks
