Introduction
============
------------------------
First of all, the Fuel deployment ISO image needs to be retrieved, the
-Fuel .iso image of the AArch64 Brahmaputra release can be found at *Reference: 2*
+ArmbandFuel .iso image of the AArch64 Brahmaputra release can be found
+at *Reference: 2*
Building the ISO image
----------------------
-Alternatively, you may build the .iso from source by cloning the
-opnfv/armband git repository. To retrieve the repository for the AArch64 Brahmaputra 3.0 release use the following command:

baseline required to replicate the Brahmaputra release:
-$ git checkout stable/brahmaputra
+$ git checkout brahmaputra.3.0
Go to the armband directory and build the .iso:

Next, familiarize yourself with Fuel by reading the following documents:

=====================
The following minimum hardware requirements must be met for the
-installation of Brahmaputra using Fuel:

Help with Hardware Requirements
===============================
#. In the "Network Setup" section - Configure DHCP/Static IP information for your FUEL node - For example, ETH0 is 10.20.0.2/24 for FUEL booting and ETH1 is DHCP/Static in your corporate/lab network (see figure below).
- - Configuration of ETH1 interface for connectivity into your corporate/lab network is mandatory. You need to have internet access over this interface.
- Due to the architecture of ports.ubuntu.com mirror, currently Fuel cannot create a full local mirror of all required AArch64 packages. Internet access is needed to deploy with Fuel on AArch64 nodes.
+ - **Note**: ArmbandFuel@OPNFV requires internet connectivity during bootstrap
+ image building, due to missing arm64 (AArch64) packages in the partial
+ local Ubuntu mirror (consequence of ports.ubuntu.com mirror architecture).
+
+ - Configuration of ETH1 interface for connectivity into your corporate/lab
+ network is mandatory, as internet connection is required during deployment.

#. Install the wanted plugin with the command "fuel plugins --install /opt/opnfv/<plugin-name>-<version>.<arch>.rpm"
Expected output: "Plugin ....... was successfully installed." (see figure below)
+ **NOTE**: AArch64 Brahmaputra 3.0 ships only with Opendaylight plugin,
+ see *Reference 15*.

Create an OpenStack Environment
- Select "Neutron with ML2 plugin"
- - Select "Neutron with tunneling segmentation" (Required when using the ODL or ONOS plugins)
+ - Select "Neutron with tunneling segmentation" (Required when using the ODL plugin)
- Press <Next>
- Click on the <+Add Nodes> button
- - Check <Controller>, <Telemetry - MongoDB> and optionally an SDN Controller role (OpenDaylight controller/ONOS) in the Assign Roles Section.

- Check one node which you want to act as a Controller from the bottom half of the screen

-OPTIONAL - Set Local Mirror Repos
+OPTIONAL - UNTESTED - Set Local Mirror Repos
---------------------------------
+**NOTE**: AArch64 Brahmaputra 3.0 does not fully support local Ubuntu mirrors,
+or at least does not ship with arm64 packages in local repos by default.
+In order to use local (partial) Ubuntu mirrors, one should add arm64 packages
+by hand to the existing amd64 mirrors and re-generate repo metadata.
+Local MOS/Auxiliary repos contain packages for both amd64 and arm64.
+
+**NOTE**: Below instruction assume you already added (by hand) arm64
+Ubuntu necessary packages to the local repository!
+
The following steps can be executed if you are in an environment with
no connection to the Internet. The Fuel server delivers a local repo
that can be used for installation / deployment of openstack.
- Allow tests to run and investigate results where appropriate
+ - Check *Reference 15* for known issues / limitations on AArch64, like
+ unsupported migration tests when using a GICv3 interrupt controller
