3. To access and investigate an undercloud node, get the IP address of the node from the undercloud:

   Copy to Clipboard Toggle word wrap

   (undercloud) $ source ~/stackrc
   (undercloud) $ openstack server list
    +-------+------------------------+---+----------------------+---+
    | ID    | Name                   |...| Networks             |...|
    +-------+------------------------+---+----------------------+---+
    | d1... | overcloud-controller-0 |...| ctlplane=*10.200.0.11* |...|
    ...

4. To log in to one of the overcloud nodes, run the following commands:

   Copy to Clipboard Toggle word wrap

   (undercloud) $ source ~/overcloudrc
   (overcloud) $ ssh [NODE_NAME]@[NODE_IP]

   Replace the name and IP address with the actual values from your deployment.
