Configure Two Bonded Adapters
|
||||
-----------------------------
|
||||
|
||||
The following example set the xCAT properties for compute node ``cn1`` to create:
|
||||
|
||||
* Compute node ``cn1`` has two physical NICs: eth2 and eth3
|
||||
* Bond eth2 and eth3 as ``bond0``
|
||||
* Assign ip ``40.0.0.1`` to the bonded interface ``bond0``
|
||||
|
||||
Define attributes in the ``nics`` table
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
|
||||
#. Using the ``mkdef`` or ``chdef`` commands
|
||||
|
||||
a. Compute node ``cn1`` has two physical NICs: ``eth2`` and ``eth3`` ::
|
||||
|
||||
chdef cn1 nictypes.eth2=ethernet nictypes.eth3=ethernet
|
||||
|
||||
b. Define ``bond0`` and bond ``eth2`` and ``eth3`` as ``bond0`` ::
|
||||
|
||||
chdef cn1 nictypes.bond0=bond nicdevices.bond0="eth2|eth3"
|
||||
chdef cn1 nicips.bond0=40.0.0.1
|
||||
|
||||
Add network object into the networks table
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
Use the ``chdef`` command to add/modify the networks in the ``networks`` table ::
|
||||
|
||||
chdef -t network net40 net=40.0.0.0 mask=255.0.0.0
|
||||
chdef cn1 nicnetworks.bond0=net40
|
||||
|
||||
Add ``confignetwork`` into the node's postscripts list
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
Use command below to add ``confignetwork`` into the node's postscripts list ::
|
||||
|
||||
chdef cn1 -p postscripts=confignetwork
|
||||
|
||||
|
||||
During OS deployment on compute node, ``confignetwork`` postscript will be executed.
|
||||
If the compute node is already running, use ``updatenode`` command to run ``confignetwork`` postscript without rebooting the node::
|
||||
|
||||
updatenode cn1 -P confignetwork
|
||||
|
||||
|
||||
Verify bonding mode
|
||||
~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
Login to compute node cn1 and check bonding options in ``/etc/sysconfig/network-scripts/ifcfg-bond0`` file ::
|
||||
|
||||
BONDING_OPTS="mode=802.3ad xmit_hash_policy=layer2+3"
|
||||
|
||||
|
||||
* ``mode=802.3ad`` requires additional configuration on the switch.
|
||||
* ``mode=2`` can be used for bonding without additional switch configuration.
|
||||
|
||||
If changes are made to ``/etc/sysconfig/network-scripts/ifcfg-bond0`` file, restart network service.

Configure BOND, VLAN and BRIDGES
|
||||
--------------------------------
|
||||
|
||||
The ``confignetwork`` postscript can be used to configure the network interfaces on the compute nodes to support VLAN, BONDs, and BRIDGES. In order for the ``confignetwork`` postscript to run successfully, the following attributes must be configured for the node in the ``nics`` table:
|
||||
|
||||
* ``nicips``
|
||||
* ``nictypes``
|
||||
* ``nicnetworks``
|
||||
* ``nicdevices`` - resolves the relationship among the physical network interface devices
|
||||
|
||||
The following example set the xCAT properties for compute node ``cn1`` to achieve the following network configuration using the ``confignetwork`` postscript:
|
||||
|
||||
* Compute node ``cn1`` has two physical NICs: ``eth2`` and ``eth3``
|
||||
* Bond ``eth2`` and ``eth3`` as ``bond0``
|
||||
* From ``bond0``, create 2 VLANs: ``bond0.1`` and ``bond0.2``
|
||||
* Make bridge ``br1`` using ``bond0.1`` with IP (10.0.0.1)
|
||||
* Make bridge ``br2`` using ``bond0.2`` with IP (20.0.0.1)
|
||||
|
||||
Define attributes in the ``nics`` table
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
Chose one of two methods described below:
|
||||
|
||||
#. Using the ``mkdef`` or ``chdef`` commands
|
||||
|
||||
a. Compute node ``cn1`` has two physical NICs: ``eth2`` and ``eth3`` ::
|
||||
|
||||
chdef cn1 nictypes.eth2=ethernet nictypes.eth3=ethernet
|
||||
|
||||
b. Define ``bond0`` and bond ``eth2`` and ``eth3`` as ``bond0`` ::
|
||||
|
||||
chdef cn1 nictypes.bond0=bond \
|
||||
nicdevices.bond0="eth2|eth3"
|
||||
|
||||
c. From ``bond0``, create 2 VLANs: ``bond0.1`` and ``bond0.2`` ::
|
||||
|
||||
chdef cn1 nictypes.bond0.1=vlan \
|
||||
nictypes.bond0.2=vlan \
|
||||
nicdevices.bond0.1=bond0 \
|
||||
nicdevices.bond0.2=bond0
|
||||
|
||||
d. Create bridge ``br1`` using ``bond0.1`` with IP (10.0.0.1) ::
|
||||
|
||||
chdef cn1 nictypes.br1=bridge \
|
||||
nicdevices.br1=bond0.1 \
|
||||
nicips.br1=10.0.0.1 \
|
||||
nicnetworks.br1="net10"
|
||||
|
||||
e. Create bridge ``br2`` using ``bond0.2`` with IP (20.0.0.1) ::
|
||||
|
||||
chdef cn1 nictypes.br2=bridge \
|
||||
nicdevices.br2=bond0.2 \
|
||||
nicips.br2=20.0.0.1 \
|
||||
nicnetworks.br2="net20"
|
||||
|
||||
#. Using an xCAT stanza file
|
||||
|
||||
- Prepare a stanza file ``<filename>.stanza`` with content similiar to the following: ::
|
||||
|
||||
# <xCAT data object stanza file>
|
||||
cn1:
|
||||
objtype=node
|
||||
arch=x86_64
|
||||
groups=kvm,vm,all
|
||||
nicdevices.br1=bond0.1
|
||||
nicdevices.br2=bond0.2
|
||||
nicdevices.bond0.1=bond0
|
||||
nicdevices.bond0.2=bond0
|
||||
nicdevices.bond0=eth2|eth3
|
||||
nictypes.eth2=ethernet
|
||||
nictypes.eth3=ethernet
|
||||
nictypes.bond0=bond
|
||||
nictypes.bond0.1=vlan
|
||||
nictypes.bond0.2=vlan
|
||||

|
||||
nictypes.br2=bridge
|
||||
nicips.br1=10.0.0.1
|
||||
nicips.br2=20.0.0.1
|
||||
nicnetworks.br1=net10
|
||||
nicnetworks.br2=net20
|
||||
|
||||
- Using the ``mkdef -z`` option, define the stanza file to xCAT: ::
|
||||
|
||||
cat <filename>.stanza | mkdef -z
|
||||
|
||||
Define the additional networks to xCAT
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
If this is a new network being created on the compute nodes, an entry needs to be created into the xCAT database.
|
||||
|
||||
The ``nicnetworks`` attribute only defines the nic that uses the IP address.
|
||||
Other information about the network should be defined in the ``networks`` table.
|
||||
|
||||
Use the ``chdef`` command to add/modify the networks in the ``networks`` table ::
|
||||
|
||||
chdef -t network net10 net=10.0.0.0 mask=255.0.0.0
|
||||
chdef -t network net20 net=20.0.0.0 mask=255.0.0.0
|
||||
|
||||
Add ``confignetwork`` into the node's postscripts list
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
Use the following command to add ``confignetwork`` into postscript list to execute on reboot: ::
|
||||
|
||||
chdef cn1 -p postscripts=confignetwork
|
||||
|
||||
If the compute node is already running, use ``updatenode`` command to run ``confignetwork`` postscript without rebooting the node::
|
||||
|
||||
updatenode cn1 -P confignetwork

Use Customized Scripts To Configure NIC
|
||||
---------------------------------------
|
||||
|
||||
If using customized script to configure NIC, ``niccustomscripts`` for the specified nic in ``nics`` table should be configured. In the customized scripts, it can use data from xCAT DB, These data are parsed as global value from ``/xcatpost/mypostscript`` in compute node. Here is a simple example :
|
||||
|
||||
#. Compute node ``cn1`` with one physical NIC: ``eth1``
|
||||
#. Put customized script ``cfgeth1`` under xCAT MN ``/install/postscripts``
|
||||
#. Configure ``niccustomscripts`` in ``nics`` table ::
|
||||
chdef cn1 niccustomscripts.eth1=cfgeth1
|
||||
|
||||
#. The script ``cfgeth1`` uses data from xCAT DB, for example, it uses network ``net50`` from ``networks`` table ::
|
||||
|
||||
chdef -t network net50 net=50.0.0.0 mask=255.0.0.0
|
||||
|
||||
**Notes:** The network ``net50`` is parsed as ``NETWORKS_LINE1`` in ``/xcatpost/mypostscript`` as following, so script ``cfgeth1`` can use global value ``NETWORKS_LINE1`` directly ::
|
||||
|
||||
NETWORKS_LINE1='netname=net50||net=50.0.0.0||mask=255.0.0.0||mgtifname=||gateway=||dhcpserver=||tftpserver=||nameservers=||ntpservers=||logservers=||dynamicrange=||staticrange=||staticrangeincrement=||nodehostname=||ddnsdomain=||vlanid=||domain=||disable=||comments='
|
||||
|

#. When ``confignetwork`` is running in ``cn1``, ``confignetwork`` will execute ``cfgeth1`` to configure eth1, so adding ``confignetwork`` into the node's postscripts list. During OS deployment on compute node, ``confignetwork`` postscript will be executed. ::

Configure Additional Network Interfaces - confignetwork
|
||||
-------------------------------------------------------
|
||||
|
||||
The ``confignetwork`` postscript can be used to configure the network interfaces on the compute nodes to support Ethernet adapters, VLAN, BONDs, and BRIDGES. ``confignetwork`` can be used in postscripts during OS privision, it can also be executed in ``updatenode``. The way the ``confignetwork`` postscript decides what IP address to give the secondary adapter is by checking the ``nics`` table, in which the nic configuration information is stored. In order for the ``confignetwork`` postscript to run successfully, the following attributes must be configured for the node in the ``nics`` table:
|
||||
|
||||
* ``nicips``
|
||||
* ``nictypes``
|
||||
* ``nicnetworks``
|
||||
|
||||
If configuring VLAN, BOND, or BRIDGES, ``nicdevices`` in ``nics`` table must be configured. VLAN, BOND or BRIDGES is only supported on RHEL.
|
||||
|
||||
* ``nicdevices`` - resolves the relationship among the physical network interface devices
|
||||

||||

Configure Additional Network Interfaces - confignetwork
|
||||
-------------------------------------------------------
|
||||
|
||||
The ``confignetwork`` postscript can be used to configure the network interfaces on the compute nodes to support Ethernet adapters, VLAN, BONDs, and BRIDGES. ``confignetwork`` can be used in postscripts during OS privision, it can also be executed in ``updatenode``. The way the ``confignetwork`` postscript decides what IP address to give the secondary adapter is by checking the ``nics`` table, in which the nic configuration information is stored. In order for the ``confignetwork`` postscript to run successfully, the following attributes must be configured for the node in the ``nics`` table:
|
||||
|
||||
* ``nicips``
|
||||
* ``nictypes``
|
||||
* ``nicnetworks``
|
||||
|
||||
If configuring VLAN, BOND, or BRIDGES, ``nicdevices`` in ``nics`` table must be configured. VLAN, BOND or BRIDGES is only supported on RHEL.
|
||||
|
||||
* ``nicdevices`` - resolves the relationship among the physical network interface devices
|
||||
|
||||
The following scenarios are examples to configure Ethernet adapters/BOND/VLAN/Bridge.
|
||||
|
||||
#. Configure Ethernet adapters:
|
||||
|
||||
* Scenario 1: :doc:`Configure Ethernet Network Interface <../../../../common/deployment/network/cfg_network_ethernet_nic>`
|
||||
To configure Ethernet install NIC or other Ethernet network adapters as static
|
||||
|
||||
#. Configure BOND **[RHEL]**:
|
||||
|
||||
* Scenario 2: :doc:`Configure Bond using two Ethernet Adapters <../../../../common/deployment/network/cfg_network_bond>`
|
||||
|
||||
#. Configure VLAN **[RHEL]**:
|
||||
|
||||
* Scenario 3: :doc:`Configure VLAN Based on Ethernet Adapter <../../../../common/deployment/network/cfg_network_vlan>`
|
||||
* Scenario 4: :doc:`Configure VLAN Based on Bond Adapters <../../../../common/deployment/network/cfg_network_bond_vlan>`
|
||||
|
||||
#. Configure Bridge **[RHEL]**:
|
||||
|
||||
* Scenario 5: :doc:`Configure Bridge Based On Ethernet NIC <../../../../common/deployment/network/cfg_network_bridge>`
|
||||
* Scenario 6: :doc:`Configure Bridge Based on Bond Adapters <../../../../common/deployment/network/cfg_network_bond_bridge>`
|
||||
* Scenario 7: :doc:`Configure Bridge Based on VLAN <../../../../common/deployment/network/cfg_network_vlan_bridge>`
|
||||
|
||||
* Scenario 8: :doc:`Configure Bridge Based on VLAN,VLAN use BOND adapter <../../../../common/deployment/network/cfg_network_bond_vlan_bridge>`
