Hi, Vlad:
  No, I didn't reboot the server after a successful OFED installation,
and I didn't restart the openibd either. I don't remember I did this
with OFED-3.18 release.

I follow your suggestion, did a reboot after the installation. Now it works fine!
[root at rhel73_host1_guest1_local_htx ~]# modprobe rpcrdma
[root at rhel73_host1_guest1_local_htx ~]# 
[root at rhel73_host1_guest1_local_htx ~]# lsmod |grep rpcrdma
rpcrdma               106978  0 

[root at rhel73_host1_guest1_local_htx ~]# modprobe -r rpcrdma
[root at rhel73_host1_guest1_local_htx ~]# 

I haven't tested the functionality yet. At least module is loading fine now.

Thanks for the help! - David Dai
