We don't have parameter "True" of option "--support-standalone-ports". We use [--support-standalone-ports | --unsupport-standalone-ports]. Thus, I remove parameter "True" of --support-standalone-ports of guide. Closes-Bug: #1640592 Change-Id: I2c94c9ff869a4c62e994fa8fd9e312c4f4c0ff39

Port groups support
|
|
===================
|
|
|
|
The Bare Metal service supports static configuration of port groups (bonds) in
|
|
the instances via configdrive. See `kernel documentation on bonding`_ to see
|
|
why it may be useful and how it is setup in linux. The sections below describe
|
|
how to make use of them in the Bare Metal service.
|
|
|
|
Switch-side configuration
|
|
-------------------------
|
|
|
|
If port groups are desired in the ironic deployment, they need to be configured
|
|
on the switches. It needs to be done manually, and the mode and properties
|
|
configured on the switch have to correspond to the mode and properties that
|
|
will be configured on the ironic side, as bonding mode and properties may be
|
|
named differently on your switch, or have possible values different from the
|
|
ones described in `kernel documentation on bonding`_. Please refer to your
|
|
switch configuration documentation for more details. In the future, we may
|
|
pass the port group mode and properties to ML2 drivers so that they can do the
|
|
configuration automatically, but it is not supported as of now.
|
|
|
|
Provisioning and cleaning cannot make use of port groups if they need to boot
|
|
the deployment ramdisk via (i)PXE. If your switches or desired port group
|
|
configuration do not support port group fallback, which will allow port group
|
|
members to be used by themselves, you need to set port group's
|
|
``standalone_ports_supported`` value to be ``False`` in ironic, as it is
|
|
``True`` by default.
|
|
|
|
Port groups configuration in the Bare Metal service
|
|
---------------------------------------------------
|
|
|
|
Port group configuration is supported in ironic API microversions 1.26, the
|
|
CLI commands below specify it for completeness.
|
|
|
|
#. When creating a port group, the node to which it belongs must be specified,
|
|
along with, optionally, its name, address, mode, properties, and if it
|
|
supports fallback to standalone ports::
|
|
|
|
openstack --os-baremetal-api-version 1.26 baremetal port group create \
|
|
--node $NODE_UUID --name test --address fa:ab:25:48:fd:ba --mode 802.3ad \
|
|
--property miimon=100 --property xmit_hash_policy="layer2+3" \
|
|
--support-standalone-ports
|
|
|
|
A port group can also be updated with ``openstack baremetal port group set``
|
|
command, see its help for more details.
|
|
|
|
If an address is not specified, the port group address on the deployed
|
|
instance will be the same as the address of the neutron port that is
|
|
attached to the port group. If the neutron port is not attached, the port
|
|
group will not be configured.
|
|
|
|
.. note::
|
|
|
|
In standalone mode, port groups have to be configured manually. It can
|
|
be done either statically inside the image, or by generating the
|
|
configdrive and adding it to the node's ``instance_info``. For more
|
|
information on how to configure bonding via configdrive, refer to
|
|
`cloud-init documentation <https://cloudinit.readthedocs.io/en/latest/topics/datasources/configdrive.html#version-2>`_
|
|
and `code <https://git.launchpad.net/cloud-init/tree/cloudinit>`_.
|
|
cloud-init version 0.7.7 or later is required for bonding configuration
|
|
to work.
|
|
|
|
If the port group's address is not explicitly set in standalone mode, it
|
|
will be set automatically by the process described in
|
|
`kernel documentation on bonding`_.
|
|
|
|
During interface attachment, port groups have higher priority than ports,
|
|
so they will be used first. (It is not yet possible to specify which one is
|
|
desired, a port group or a port, in an interface attachment request). Port
|
|
groups that don't have any ports will be ignored.
|
|
|
|
The mode and properties values are described in the
|
|
`kernel documentation on bonding`_. The default port group mode is
|
|
``active-backup``, and this default can be changed by setting the
|
|
``[DEFAULT]default_portgroup_mode`` configuration option in the ironic API
|
|
service configuration file.
|
|
|
|
#. Associate ports with the created port group.
|
|
|
|
It can be done on port creation::
|
|
|
|
openstack --os-baremetal-api-version 1.26 baremetal port create \
|
|
--node $NODE_UUID --address fa:ab:25:48:fd:ba --port-group test
|
|
|
|
Or by updating an existing port::
|
|
|
|
openstack --os-baremetal-api-version 1.26 baremetal port set \
|
|
$PORT_UUID --port-group $PORT_GROUP_UUID
|
|
|
|
When updating a port, the node associated with the port has to be in
|
|
``enroll``, ``manageable``, or ``inspecting`` states. A port group can have
|
|
the same or different address as individual ports.
|
|
|
|
#. Boot an instance (or node directly, in case of using standalone ironic)
|
|
providing an image that has cloud-init version 0.7.7 or later and supports
|
|
bonding.
|
|
|
|
When the deployment is done, you can check that the port group is set up
|
|
properly by running the following command in the instance::
|
|
|
|
cat /proc/net/bonding/bondX
|
|
|
|
where ``X`` is a number autogenerated by cloud-init for each configured port
|
|
group, in no particular order. It starts with 0 and increments by 1 for every
|
|
configured port group.
