You can use the stack user account to run commands that require elevated privileges such as deploying the back end or loading environment variables for accessing the overcloud. For more information about the stack user, see Creating the stack user in the Director Installation and Usage guide.

The environment file in Chapter 3, Create the Environment File, configures the Block Storage service to use two NetApp back ends. The following snippet displays the relevant settings: 

enabled_backends = netapp1,netapp2

volume_driver=cinder.volume.drivers.netapp.common.NetAppDriver
netapp_login=root
netapp_storage_protocol=iscsi
netapp_password=p@$$w0rd
netapp_storage_family=ontap_7mode
netapp_server_port=80
netapp_server_hostname=10.35.64.11

[netapp2]
