This section details the steps required to configure the TOYOU ACS5000 storage cinder driver.

  1. In the cinder.conf configuration file under the [DEFAULT] section, set the enabled_backends parameter.

    enabled_backends = ACS5000-1
  2. Add a backend group section for the backend group specified in the enabled_backends parameter.

  3. In the newly created backend group section, set the following configuration options:

    # The driver path
    volume_driver = cinder.volume.drivers.toyou.acs5000.acs5000_iscsi.Acs5000ISCSIDriver
    # Management IP of TOYOU ACS5000 storage array
    san_ip =
    # Management username of TOYOU ACS5000 storage array
    san_login = cliuser
    # Management password of TOYOU ACS5000 storage array
    san_password = clipassword
    # The Pool used to allocated volumes
    acs5000_volpool_name = pool01
    # Backend name
    volume_backend_name = ACS5000
