This change addresses a long-standing issue in rST documentation imported from XML.
That import process added backslash escapes in front of various characters. The three
most common being '(', ')', and '_'.
These instances are removed.

Convert a Duplex System to Direct Connection
|
|
============================================
|
|
|
|
On a |prod| |AIO| system configured to use switch-based network connection for
|
|
the management and cluster host networks, you can convert to direct
|
|
\(peer-to-peer) connection.
|
|
|
|
The connection type is initially configured at installation. You can change
|
|
it at any time. You must use the CLI to make the change.
|
|
|
|
.. xbooklinkFor more about the available connection modes,
|
|
see |planning-doc|: `Networks for a Duplex System <networks-for-a-starlingx-duplex-system>`.

|
|
|
#. Use the :command:`system modify` command to specify direct
|
|
connection (**duplex-direct**).
|
|
|
|
.. code-block:: none
|
|
|
|
~(keystone_admin)]$ system modify --system_mode=duplex-direct
|
|
|
|
This raises **Config-out-of-date** alarm messages on both controllers.
|
|
|
|
#. Lock and then unlock the standby controller to update its configuration.
|
|
|
|
Wait for the controller to be reported as **Unlocked**, **Available**,
|
|
and **Online**, and its **Config-out-of-date** alarm message to be
|
|
cleared.
|
|
|
|
#. Swact the controllers.
|
|
|
|
#. Lock the new standby controller.
|
|
|
|
#. Disconnect the management and infrastructure cables from the |ToR| switch.
|
|
|
|
This raises **Port failed** and **Interface failed** alarms on the
|
|
active controller for the management and infrastructure interfaces.
|
|
|
|
#. Reconnect the cables in a peer-to-peer configuration.
|
|
|
|
Wait for the network interface alarms to be cleared.
|
|
|
|
#. Unlock the standby controller to update its configuration.
|
|
|
|
Wait for the controller to be reported as **Unlocked**, **Available**,
|
|
and **Online**, and its **Config-out-of-date** alarm message to be
|
|
cleared.

The system is now reconfigured to use direct connections for the internal
|
|
networks.
