Configuring PXE boot interface
|
|
==============================
|
|
|
|
Enable persistent boot device for deploy/clean operation
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
Ironic uses non-persistent boot for cleaning/deploying phases as default,
|
|
in PXE interface. For some drivers, a persistent change is far more
|
|
costly than a non-persistent one, so this can bring performance improvements.
|
|
|
|
Enable persistent boot device on node
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
1. Set the flag ``force_persistent_boot_device`` to ``True`` in the node's ``driver_info``::
|
|
|
|
$ openstack baremetal node set --driver-info force_persistent_boot_device=True <node>
|
|
|
|
.. note::
|
|
It's recommended to check if the node's state has not changed as there
|
|
is no way of locking the node between these commands.
|
|
|
|
Once the flag is present, the next cleaning and deploy steps will be done
|
|
with persistent boot for that node.
