Dell EMC PowerStore driver
|
||||
==========================
|
||||
|
||||
This section explains how to configure and connect the block
|
||||
storage nodes to an PowerStore storage cluster.
|
||||
|
||||
Supported operations
|
||||
~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
- Create, delete, attach and detach volumes.
|
||||
- Create, delete volume snapshots.
|
||||
- Create a volume from a snapshot.
|
||||
- Copy an image to a volume.
|
||||
- Copy a volume to an image.
|
||||
- Clone a volume.
|
||||
- Extend a volume.
|
||||
- Get volume statistics.
|
||||
- Attach a volume to multiple servers simultaneously (multiattach).
|
||||
- Revert a volume to a snapshot.
|
||||
|
||||
Driver configuration
|
||||
~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
Add the following content into ``/etc/cinder/cinder.conf``:
|
||||
|
||||
.. code-block:: ini
|
||||
|
||||
[DEFAULT]
|
||||
enabled_backends = powerstore
|
||||
|
||||
[powerstore]
|
||||
# PowerStore REST IP
|
||||
san_ip = <San IP>
|
||||
# PowerStore REST username and password
|
||||
san_login = <San username>
|
||||
san_password = <San Password>
|
||||
# Storage protocol
|
||||
storage_protocol = <Storage protocol> # FC or iSCSI
|
||||
# Volume driver name
|
||||
volume_driver = cinder.volume.drivers.dell_emc.powerstore.driver.PowerStoreDriver
|
||||
# Backend name
|
||||
volume_backend_name = <Backend name>
|
||||
# PowerStore appliances
|
||||
powerstore_appliances = <Appliances names> # Ex. Appliance-1,Appliance-2
|
||||
# PowerStore allowed ports
|
||||
powerstore_ports = <Allowed ports> # Ex. 58:cc:f0:98:49:22:07:02,58:cc:f0:98:49:23:07:02
|
||||
|
||||
Driver options
|
||||
~~~~~~~~~~~~~~
|
||||
|
||||
The driver supports the following configuration options:
|
||||
|
||||
.. config-table::
|
||||
:config-target: PowerStore
|
||||
|
||||
cinder.volume.drivers.dell_emc.powerstore.driver
|
||||
|
||||
SSL support
|
||||
~~~~~~~~~~~
|
||||
|
||||
To enable the SSL certificate verification, modify the following options in the
|
||||
``cinder.conf`` file:
|
||||
|
||||
.. code-block:: ini
|
||||
|
||||
driver_ssl_cert_verify = True
|
||||
driver_ssl_cert_path = <path to the CA>
|
||||
|
||||
By default, the SSL certificate validation is disabled.
|
||||
|
||||
If the ``driver_ssl_cert_path`` option is omitted, the system default CA will
|
||||
be used.
|
||||
|
||||
Thin provisioning and compression
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
The driver creates thin provisioned compressed volumes by default.
|
||||
Thick provisioning is not supported.
