[openib-general] [CM]problem while connecting

[Ian Jiang]

Hi Roland,
Thanks for your reply!
The previous problem disappeared after I modified my code as you told. But
another one while connecting hold me up:

Feb 28 23:05:02 linux3 kernel:  VIPKL(1):
var/tmp/IBGD/tmp/openib/infiniband/ib_verbs/hw/mellanox-hca/vip/qpm.c[1108]:

to INIT failed

Was this caused by my improper QP creation?
Any suggestion is appreciated. Here are the relative codes of my own:

    qp_param.receive_policy = IB_WQ_SIGNAL_ALL;
    qp_param.transport      = IB_TRANSPORT_RC;
    qp_param.device_specific = NULL;

  res = ib_qp_create(&qp_param,
            &params_p->ib_res.cm_qp_p,
            &params_p->ib_res.cm_qpn);
    if (res) {
        PRINT_ERR("ib_qp_create failed\n");
        cm_ib_clean(&params_p->ib_res);
        return -1;
    }
    PRINT_TRACE("QP created: 0x%p, Num: 0x%x\n", params_p->ib_res.cm_qp_p,
params_p->ib_res.cm_qpn);
