=============================================
Seagate Array Fibre Channel and iSCSI drivers
=============================================
The ``STXFCDriver`` and ``STXISCSIDriver`` Cinder drivers allow the
Seagate Technology (STX) storage arrays to be used for Block Storage in
OpenStack deployments.
System requirements
~~~~~~~~~~~~~~~~~~~
To use the Seagate drivers, the following are required:
- Seagate storage array with:
- iSCSI or FC host interfaces
- G28x firmware or later
- Network connectivity between the OpenStack host and the array management
interfaces
- The HTTPS or HTTP protocol must be enabled on the array
Supported operations
~~~~~~~~~~~~~~~~~~~~
- Create, delete, attach, and detach volumes.
- Create, list, and 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.
- Migrate a volume with back-end assistance.
- Retype a volume.
- Manage and unmanage a volume.
Configuring the array
~~~~~~~~~~~~~~~~~~~~~
#. Verify that the array can be managed via an HTTPS connection. HTTP can also
be used if ``driver_use_ssl`` is set to (or defaults to) False
in the ``cinder.conf`` file.
Confirm that virtual pools A and B are present if you plan to use virtual
pools for OpenStack storage.
If you plan to use vdisks instead of virtual pools, create or identify one
or more vdisks to be used for OpenStack storage; typically this will mean
creating or setting aside one disk group for each of the A and B
controllers.
#. Edit the ``cinder.conf`` file to define a storage back-end entry for each
storage pool on the array that will be managed by OpenStack. Each entry
consists of a unique section name, surrounded by square brackets, followed
by options specified in a ``key=value`` format.
* The ``seagate_pool_name`` value specifies the name of the storage pool
or vdisk on the array.
* The ``volume_backend_name`` option value can be a unique value, if you
wish to be able to assign volumes to a specific storage pool on the
array, or a name that is shared among multiple storage pools to let the
volume scheduler choose where new volumes are allocated.
#. The following ``cinder.conf`` options generally have identical values
for each backend section on the array:
* ``volume_driver`` specifies the Cinder driver name.
* ``san_ip`` specifies the IP addresses or host names of the array's
management controllers.
* ``san_login`` and ``san_password`` specify the username and password
of an array user account with ``manage`` privileges
* ``driver_use_ssl`` must be set to True to enable use of the HTTPS
protocol.
* ``seagate_iscsi_ips`` specfies the iSCSI IP addresses
for the array if using the iSCSI transport protocol
In the examples below, two back ends are defined, one for pool A and one for
pool B, and a common ``volume_backend_name`` is used so that a single
volume type definition can be used to allocate volumes from both pools.
