Configuring Cinder with a NetApp Backend

This guide assumes that your undercloud is already installed and ready to deploy an overcloud.

Deploying the Overcloud

Note

The Deploying with Heat Templates doc has a more detailed explanation of the following steps.

1. Copy the NetApp configuration file to your home directory:

   sudo cp /usr/share/openstack-tripleo-heat-templates/environments/cinder-netapp-config.yaml ~
   

2. Edit the permissions (user is typically stack):

   sudo chown $USER ~/cinder-netapp-config.yaml
   sudo chmod 755 ~/cinder-netapp-config.yaml
   

3. Edit the parameters in this file to fit your requirements. Ensure that the following line is changed:

   OS::TripleO::ControllerExtraConfigPre: /usr/share/openstack-tripleo-heat-templates/puppet/extraconfig/pre_deploy/controller/cinder-netapp.yaml
   

4. Continue following the TripleO instructions for deploying an overcloud. Before entering the command to deploy the overcloud, add the environment file that you just configured as an argument:

   openstack overcloud deploy --templates -e ~/cinder-netapp-config.yaml
   

5. Wait for the completion of the overcloud deployment process.

Creating a NetApp Volume

Note

The following steps will refer to running commands as an admin user or a tenant user. Sourcing the overcloudrc file will authenticate you as the admin user. You can then create a tenant user and use environment files to switch between them.

1. Create a new volume type that maps to the new NetApp backend [admin]:

   cinder type-create [name]
   cinder type-key [name] set volume_backend_name=tripleo_netapp
   

2. Create the volume [admin]:

   cinder create --volume-type [type name] [size of volume]
   

3. Attach the volume to a server:

   nova volume-attach <server> <volume> <device>
