Changed paths to avoid '..', which breaks symlinks in newer versions of sphinx. Consolidated installation include files under /_includes. Prefixed r5 versions with 'r5_' Moved files that are used up/down, but at different paths under /shared/_includes and /shared/figures Move two include files to /_includes Moved addtional images to /shared/figures/... Required for DS platform builds. Signed-off-by: Ron Stone <ronald.stone@windriver.com> Change-Id: Ia38f4205c5803b3d1fc043e6c59617c34a4e5cbd Signed-off-by: Ron Stone <ronald.stone@windriver.com>

Add Compute Nodes to an Existing Duplex System
|
|
==============================================
|
|
|
|
You can add up to 6 compute nodes to an existing Duplex system by following
|
|
the standard procedures for adding compute nodes to a system.
|
|
|
|

|
|
|
|
Before adding compute nodes to a duplex system, you can either add and
|
|
provision platform RAM and CPU cores on the controllers or reallocate RAM and
|
|
CPU cores from the VMs to the platform.
|
|
|
|
.. xbooklink To add platform RAM and CPU cores on the controllers,
|
|
see |node-doc|: `Changing Hardware Components for a Controller Host <changing-hardware-components-for-a-controller-host>`.
|
|
|
|
The requirements for each added compute node are as follows:

#. Provision the resources.
|
|
|
|
To allocate resources to the controller, update the controller resource
|
|
inventory in |prod-os|. See |node-doc|: :ref:`Memory Tab <memory-tab>` and
|
|
:ref:`Processor Tab <processor-tab>`.
|
|
|
|
#. Add the hosts \(compute nodes\).
|
|
|
|
Add one or more host entries to the system inventory.
|
|
|
|
.. xbooklink See |prod|| Installation Overview: `Adding Hosts Using the host-add Command <adding-hosts-using-the-host-add-command>`.
