Chapter 5. Test the Configured Back End

After you deploy the back end, test that you can successfully create volumes on it.


  1. Log in to the undercloud node as the stack user.
  2. Source the overcloudrc credentials file:

    $ source /home/stack/overcloudrc
  3. Create a new volume type that you can use to specify the new back end. Run the following command to create a volume type called dellsc, run:

    $ cinder type-create dellsc
  4. Map the new volume type to the new back end, tripleo_dellsc , as defined through the CinderDellScBackendName parameter in Chapter 3, Define a Single Back End:

    $ cinder type-key dellsc set volume_backend_name=tripleo_dellsc
  5. Create a new 2GB volume on the new back end:

    $ cinder create --volume-type dellsc 2
