Expansion Guide
===============
Edit NETWORK File
-----------------
The below file is the inventory template of deployment nodes:
"./deploy/conf/hardware_environment/huawei-pod1/network.yml"
You need to edit the network.yml which you had edited the first deployment.
NOTE:
External subnet's ip_range should exclude the IPs those have already been used.
Edit DHA File
-------------
The below file is the inventory template of deployment nodes:
"./deploy/conf/hardware_environment/expansion-sample/hardware_cluster_expansion.yml"
You can write your own IPMI IP/User/Password/Mac address/roles reference to it.
- name -- Host name for deployment node after installation.
- ipmiIP -- IPMI IP address for deployment node. Make sure it can access
from Jumphost.
- ipmiUser -- IPMI Username for deployment node.
- ipmiPass -- IPMI Password for deployment node.
- mac -- MAC Address of deployment node PXE NIC .
**Set TYPE/FLAVOR and POWER TOOL**
E.g.
.. code-block:: yaml
TYPE: baremetal
FLAVOR: cluster
POWER_TOOL: ipmitool
**Set ipmiUser/ipmiPass and ipmiVer**
E.g.
.. code-block:: yaml
ipmiUser: USER
ipmiPass: PASSWORD
ipmiVer: '2.0'
**Assignment of roles to servers**
E.g. Only increase one compute node
.. code-block:: yaml
hosts:
- name: host6
mac: 'E8:4D:D0:BA:60:45'
interfaces:
- eth1: '08:4D:D0:BA:60:44'
ipmiIp: 172.16.131.23
roles:
- compute
E.g. Increase two compute nodes
.. code-block:: yaml
hosts:
- name: host6
mac: 'E8:4D:D0:BA:60:45'
interfaces:
- eth1: '08:4D:D0:BA:60:44'
ipmiIp: 172.16.131.23
roles:
- compute
- name: host6
mac: 'E8:4D:D0:BA:60:78'
interfaces:
- eth1: '08:4D:56:BA:60:83'
ipmiIp: 172.16.131.23
roles:
- compute
Start Expansion
~~~~~~~~~~~~~~~
1. Edit network.yml and dha.yml file
You need to Edit network.yml and virtual_cluster_expansion.yml or
hardware_cluster_expansion.yml. Edit the DHA and NETWORK envionment variables.
External subnet's ip_range and management ip should be changed as the first 6
IPs are already taken by the first deployment.
E.g.
.. code-block:: bash
--- network.yml 2017-02-16 20:07:10.097878150 +0800
+++ network-expansion.yml 2017-05-03 10:01:34.537379013 +0800

2. Edit deploy.sh
2.1. Set EXPANSION and VIRT_NUMBER.
VIRT_NUMBER decide how many virtual machines needs to expand when virtual expansion
E.g.
.. code-block:: bash
export EXPANSION="true"
export MANAGEMENT_IP_START="10.1.0.55"
export VIRT_NUMBER=1
export DEPLOY_FIRST_TIME="false"
2.2. Set scenario that you need to expansion
E.g.
.. code-block:: bash
# DHA is your dha.yml's path
export DHA=./deploy/conf/hardware_environment/expansion-sample/hardware_cluster_expansion.yml
# NETWORK is your network.yml's path
export NETWORK=./deploy/conf/hardware_environment/huawei-pod1/network.yml
Note: Other environment variable shoud be same as your first deployment.
Please check the environment variable before you run deploy.sh.
2. Run ``deploy.sh``
.. code-block:: bash
./deploy.sh
