Issue with SmartNIC Configuration on nodes

[Hemil Panchiwala]

Hi,

I’m encountering a problem while setting up nodes with SmartNICs on the Fabric testbed. While I can obtain the MAC addresses for the NICs, other crucial fields such as Physical Device, Device, and IP Address are showing up as None. This is causing issues when I try to execute scripts on the nodes.

Setup Details

I’m using the following code to set up the nodes and SmartNICs:

send_params = {"name": "sender", "site": "SEAT", "host": None, "image": "default_ubuntu_20"} 
send_nic_params = {"model": "NIC_ConnectX_5", "name": "SmartNIC"}
slice = fablib.new_slice(name=slice_name)
send_node = slice.add_node(**send_params)
send_iface = send_node.add_component(**send_nic_params).get_interfaces()[0]

I am attaching the details of the interface printed once the setup is done.

Error

When I try to execute the script (setup.sh as shown below in code) on the node, I am getting an “Authentication failed” error:

send = slice.get_node(send_params["name"])
send_iface = send.get_interface(network_name=network_name)
send.execute(f"echo '{setup_script.format(interface_name=send_iface.get_device_name())}' > ~/setup.sh && chmod +x ~/setup.sh")

This error seems to occur in the last line where send_iface.get_device_name() is returning None.

Questions

I am not sure why are the Physical Device, Device, and IP Address fields showing up as None for the SmartNIC. Also, how can I resolve the “Authentication failed” error? Any insights or suggestions would be greatly appreciated. Thank you for your help!
