Hi,

 

I have the SPDK target working for AIO and Malloc.

 

I now have configured NVMe device on the same setup, but not able to start the target, as the target is not finding the nvme0 bdev.

 

Do we have any other dependency for configuring Nvme devices ?

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.

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

From initiator I tried discover and connect

can you please help on why I am not able to connect in this configuration.
