+-----------------+------------------------+
| Storage model | Firmware version |
+=================+========================+
| XP8 | 90-01-41 or later |
+-----------------+------------------------+
| XP7 | 80-05-43 or later |
+-----------------+------------------------+
Required storage licenses:
* Thin Provisioning
* Fast Snap
Supported operations
~~~~~~~~~~~~~~~~~~~~
* Create, delete, attach, and detach volumes.
* Create, list, and delete volume snapshots.
* Create a volume from a snapshot.
* Create, list, update, and delete consistency groups.
* Create, list, and delete consistency group snapshots.
* Copy a volume to an image.
* Copy an image to a volume.
* Clone a volume.
* Extend a volume.
* Migrate a volume.
* Get volume statistics.
* Efficient non-disruptive volume backup.
* Manage and unmanage a volume.
* Attach a volume to multiple instances at once (multi-attach).
* Revert a volume to a snapshot.
.. note::
The volume having snapshots cannot be extended in this driver.
Configuration
~~~~~~~~~~~~~
Set up HPE XP storage
----------------------
You need to specify settings as described below for storage systems. For
details about each setting, see the user's guide of the storage systems.
#. User accounts
Create a storage device account belonging to the Administrator User Group.
#. THP pool
Create a THP pool that is used by the driver.
#. Ports
Enable Port Security for the ports used by the driver.
Set up HPE XP storage volume driver
------------------------------------
Set the volume driver to HPE XP block storage driver by setting the
volume_driver option in the cinder.conf file as follows:
If you use Fibre Channel:
.. code-block:: ini
[hpe_xp]
volume_driver = cinder.volume.drivers.hpe.xp.hpe_xp_fc.HPEXPFCDriver
volume_backend_name = hpexp_fc
san_ip = 1.2.3.4
san_login = hpexpuser
san_password = password
hpexp_storage_id = 123456789012
hpexp_pools = pool0
If you use iSCSI:
.. code-block:: ini
[hpe_xp]
volume_driver = cinder.volume.drivers.hpe.xp.hpe_xp_iscsi.HPEXPISCSIDriver
volume_backend_name = hpexp_iscsi
san_ip = 1.2.3.4
san_login = hpexpuser
san_password = password
hpexp_storage_id = 123456789012
hpexp_pools = pool0
This table shows configuration options for HPE XP block storage driver.
.. config-table::
:config-target: HPE XP block storage driver
cinder.volume.drivers.hpe.xp.hpe_xp_rest
Required options
----------------
- ``san_ip``
IP address of SAN controller
- ``san_login``
Username for SAN controller
- ``san_password``
Password for SAN controller
- ``hpexp_storage_id``
Product number of the storage system.
- ``hpexp_pools``
Pool number(s) or pool name(s) of the THP pool.
