And the other choice is to remove the Host related line, which means any host can connect.

Hi Kiru,

According to the error message, I suggest that you add the Host info in the following section.

[Subsystem1]

  NQN nqn.2016-06.io.spdk:cnode1

  Core 0

  Listen RDMA 10.3.7.2:4420

  Host nqn.2016-06.io.spdk:init

                 Host nqn.2014-08.org.nvmexpress:NVMf:uuid:5e5e0064-2ad6-4a43-9c26-063e3ef6cf14

  SN SPDK00000000000001

  Namespace AIO0

Thanks.

Subject: [SPDK] NVMf target configuration issue

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
