Appendix A. Appendix

A.1. The stack user

The Creating a Director Installation User section instructs readers to create a user named stack, which in turn will be used to deploy the Overcloud. You can use the stack account to run commands that require elevated privileges, such as deploying the back end (Chapter 4, Deploy the Configured Back Ends) or loading the necessary environment variables for accessing the Overcloud (Chapter 5, Test the Configured Back End).

Presumably, if you followed the instructions in Director Installation and Usage, the stack user would already exist. As such, it would be convenient to use it as needed.

A.2. Resulting Configuration from Sample Environment File

The environment file in xref:envfile will configure the Block Storage service to use two NetApp back ends. The following snippet displays the relevant settings:

enabled_backends = netapp1,netapp2

[netapp1]
volume_backend_name=netapp_1
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]
volume_backend_name=netapp_2
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
