Volume driver configuration
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
This section describes how to configure the FusionStorage Volume Driver.
|
||||
|
||||
To configure the volume driver, follow the steps below:
|
||||
|
||||
#. Configure the ``cinder.conf`` file.
|
||||
|
||||
In the ``[default]`` block of ``/etc/cinder/cinder.conf``,
|
||||
enable the ``VOLUME_BACKEND``:
|
||||
|
||||
.. code-block:: ini
|
||||
|
||||
enabled_backends = VOLUME_BACKEND
|
||||
|
||||
Add a new block ``[VOLUME_BACKEND]``, and add the following contents:
|
||||
|
||||
.. code-block:: ini
|
||||
|
||||
[VOLUME_BACKEND]
|
||||
volume_driver = cinder.volume.drivers.fusionstorage.dsware.DSWAREDriver
|
||||
volume_backend_name = backend_name
|
||||
manager_ips =
|
||||
host1:ip1,
|
||||
host2:ip2
|
||||
storage =
|
||||
UserName: username,
|
||||
Password: password,
|
||||
RestURL: url,
|
||||
StoragePool: pool0;pool1;pool2
|
||||
|
||||
* ``volume_driver`` indicates the loaded driver.
|
||||
|
||||
* ``volume_backend_name`` indicates the name of the backend.
|
||||
|
||||
* ``manager_ips`` indicates the management host name and its corresponding IP address;
|
||||
The parameters takes the standard dict config form, such as
|
||||
manager_ips = host1:ip1, host2:ip2.
|
||||
|
||||
* ``storage`` indicates the FusionStorage and user info, include "UserName",
|
||||
"Password", "RestURL", "StoragePool". The parameters takes the standard
|
||||
dict config form.
|
||||
|
||||
#. Run the :command:`service cinder-volume restart` command to restart the
|
||||
Block Storage service.
