hi, I am trying to use the APM support in openib kernel stack and facing some problems. here are the steps I follow:
1. first resolve both the path, primary and alternate path. 2. send REQ using: active_param.primary_path = path; active_param.alternate_path = alt_path; ib_send_cm_req( cm_id, &active_param); this call doesn't return any error 3. in req_handler() we follow the same steps as we have done without APM.. i.e. create qpairs, change qp state to RTR and then send REP. however, when trying to change state to RTR usinb ib_modify_qp() I get an error (-22). two info: same code will work if I pass alt_path as NULL or change the alt_path as primary path. I must be missing something here, I assume this basic APM feature works in RHEL4 update 4 distribtion of openib stack. thanks, som. _______________________________________________ openib-general mailing list [email protected] http://openib.org/mailman/listinfo/openib-general To unsubscribe, please visit http://openib.org/mailman/listinfo/openib-general
