Hi All,



I am trying to get the nvmf configuration going with SPDK.



I have the following configuration,



*# ofed 2.4 on both target and initiator*

*# SPDK + 3.18 kernel on target *

*# 4.9 kernel on initiator*

*# mellanox connect3X-Pro*



*/etc/spdk/nvmf.conf*



[Global]

[Rpc]

  Enable No

  Listen 127.0.0.1

[AIO]

  AIO /dev/sdd AIO0



[Nvmf]

  MaxQueuesPerSession 4

  AcceptorPollRate 10000



[Subsystem1]

  NQN nqn.2016-06.io.spdk:cnode1

  Core 0

  Listen RDMA 10.3.7.2:4420

  Host nqn.2016-06.io.spdk:init

  SN SPDK00000000000001

  Namespace AIO0





*From initiator I tried discover and connect*



*# nvme discover -t rdma -a 10.3.7.2 -s 4420*
