#
# Configure the Dell Storage Center Driver for cinder.
#
# === Parameters
#
# [*san_ip*]
# (required) IP address of Enterprise Manager.
#
# [*san_login*]
# (required) Enterprise Manager user name.
#
# [*san_password*]
# (required) Enterprise Manager user password.
#
# [*dell_sc_ssn*]
# (required) The Storage Center serial number to use.
#
# [*target_ip_address*]
# (optional) The IP address that the iSCSI daemon is listening on.
# Defaults to undef. Only applicable for iSCSI driver.
#
# [*volume_backend_name*]
# (optional) The storage backend name.
# Defaults to the name of the backend
#
# [*backend_availability_zone*]
# (Optional) Availability zone for this volume backend.
# If not set, the storage_availability_zone option value
# is used as the default for all backends.
# Defaults to $::os_service_default.
#
# [*dell_sc_api_port*]
# (optional) The Enterprise Manager API port.
# Defaults to $::os_service_default
#
# [*dell_sc_server_folder*]
# (optional) Name of the server folder to use on the Storage Center.
# Defaults to 'srv'
#
# [*dell_sc_verify_cert*]
# (optional) Enable HTTPS SC ceritifcate verification
# Defaults to $::os_service_default
#
# [*dell_sc_volume_folder*]
# (optional) Name of the volume folder to use on the Storage Center.

#
# [*secondary_sc_api_port*]
# (optional) Secondary Dell API port.
# Defaults to $::os_service_default
#
# [*extra_options*]
# (optional) Hash of extra options to pass to the backend stanza.
# Defaults to: {}
# Example:
# { 'dellemc_sc_backend/param1' => { 'value' => value1 } }
#
# [*manage_volume_type*]
# (Optional) Whether or not manage Cinder Volume type.
# If set to true, a Cinder Volume type will be created
# with volume_backend_name=$volume_backend_name key/value.
# Defaults to false.
#
# [*use_multipath_for_image_xfer*]
# (Optional) Enables multipath configuration.
# Defaults to true.
#
# [*sc_storage_protocol*]
