TOYOU ACS5000 iSCSI driver
|
||||
==========================
|
||||
|
||||
TOYOU ACS5000 series volume driver provides OpenStack Compute instances
|
||||
with access to TOYOU ACS5000 series storage systems.
|
||||
|
||||
TOYOU ACS5000 storage can be used with iSCSI connection.
|
||||
|
||||
This documentation explains how to configure and connect the block storage
|
||||
nodes to TOYOU ACS5000 series storage.
|
||||
|
||||

Configure TOYOU ACS5000 iSCSI backend
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
|

This section details the steps required to configure the TOYOU ACS5000
|
||||
storage cinder driver.
|

||||
|
||||
|
||||
#. Add a backend group section for the backend group specified
|
||||
in the enabled_backends parameter.
|
||||
|
||||
#. In the newly created backend group section, set the
|
||||
following configuration options:
|
||||
|
||||
.. code-block:: ini
|
||||
|
||||
[ACS5000-1]
