positive.code: 8.  Click **Create Volume**.
  9.  You should see the volume appear in the list of volumes with the status **Available**.
  
  If the volume appears with the status **Error**, you need to check that your OpenStack Cinder Service is configured correctly. See [Cinder Administrator Guide](http://docs.openstack.org/admin-guide-cloud/content/managing-volumes.html) for more information.
  
  To verify that you can attach and mount a volume to an instance, perform the following steps (**assumes you have completed the steps above**):
  
  
negative.code: 7.  You should be able to leave the menu **Port to be associated** alone, but check that it points at the VM you have selected.
  8.  Click **Associate**.
  
  If the steps above do not work for you, consult the [OpenStack Networking Guide](https://docs.openstack.org/neutron/latest/admin/) for more information.
  
  Simply assigning a floating IP address to a virtual machine does not mean that virtual networking is properly configured. You will also need to ensure that the virtual machine can be reached on its floating IP address, so that calls can be made to and from the VM once it's running the BOSH Director or Cloud Foundry. The public-facing router will forward traffic at all ports to your virtual machine, so it is up to the networking configuration of your security group to provide the added layer of security by implementing a firewall.
