Node has no valid management IP.

[PHILIP CUMMINS]

I am following the Hello, Fabric first example, I have been led to believe that I have completed the configuration and validatation

ID	Name	Cores	RAM	Disk	Image	Image Type	Host	Site	Username	Management IP	State	Error	SSH Command	Public SSH Key File	Private SSH Key File
None	Node1	None	None	None	default_rocky_8	qcow2	None	BRIST	rocky		None			/home/fabric/work/fabric_config/slice_key.pub	/home/fabric/work/fabric_config/slice_key

here it the stack trace:

---------------------------------------------------------------------------
Exception                                 Traceback (most recent call last)
Cell In[7], line 4
      1 #node = slic.get_node('Node1')
      3 for node in slice.get_nodes():
----> 4     stdout, stderr = node.execute('echo Hello, FABRIC from node hostname -s')

File /opt/conda/lib/python3.11/site-packages/fabrictestbed_extensions/fablib/node.py:1455, in Node.execute(self, command, retry, retry_interval, username, private_key_file, private_key_passphrase, quiet, read_timeout, timeout, output_file, display)
   1453 management_ip = self.get_management_ip()
   1454 if not management_ip:
-> 1455     raise Exception(f"Node {self.get_name()} has no valid management IP.")
   1457 # Ensure the node is active
   1458 if self.get_reservation_state() != "Active":

Exception: Node Node1 has no valid management IP.
------------------------------e---------------------------------------------

This does match the table, the management IP field is blank, and the state is None. 

Any help would be appreciated, thank you

Hi Philip,

I can confirm that your slice is up and running. Could you please verify it from the Portal via Experiments-> My Slices.

W.r.t to Jupyter Hub, could you please re-run this notebook jupyter-examples-rel1.8.*/configure_and_validate/configure_and_validate.ipynb ?

After this, please try deleting your slice and recreating it via Hello Fabric notebook again.

Thanks,

Komal

deleting the slice, re-running the configuration and validation produces this node list:

ID	Name	Cores	RAM	Disk	Image	Image Type	Host	Site	Username	Management IP	State	Error	SSH Command	Public SSH Key File	Private SSH Key File
4ba39cec-e226-4c75-b905-07abfa96f2b8	Node1	2	8	10	default_rocky_8	qcow2	max-w1.fabric-testbed.net	MAX	rocky	2001:468:c00:ffc4:f816:3eff:fe6f:3234	Active		ssh -i /home/fabric/work/fabric_config/slice_key -F /home/fabric/work/fabric_config/ssh_config rocky@2001:468:c00:ffc4:f816:3eff:fe6f:3234	/home/fabric/work/fabric_config/slice_key.pub	/home/fabric/work/fabric_config/slice_key

the experiment now runs as expected. Hello, Fabric!

Thanks!
