Hello,

 

I have configured the target and initiator for a subsystem with 1 NVMe device in target.

Here are the errors I am getting on the initiator. I have a good NVMe device on the target side, but I am getting the error below.

If you know why the initiator does not initialize the controller and reason for the error, please let me know.

    Target log:

    Everything seems to be fine on the target application until the initiator connects to it and create a namespace.
