Hardware assisted secure erase, i.e the ``erase_devices`` clean step, is
12+
enabled by default. This is normally dependent on the `Hardware Manager
13+
<https://docs.openstack.org/ironic-python-agent/latest/contributor/hardware_managers.html>`__
14+
in use. For example, when using the GenericHardwareManager the priority would
15+
be 10, whereas if using the `ProliantHardwareManager
16+
<https://docs.openstack.org/ironic/latest/admin/drivers/ilo.html#disk-erase-support>`__
17+
it would be 0. The idea is that we will prevent the catastrophic case where
18+
data could be leaked to another tenant; forcing you to have to explicitly relax
19+
this setting if this is a risk you want to take. This can be customised by
20+
editing the following variables:
21+
22+
.. code-block::

See `Ironic documentation

<https://docs.openstack.org/ironic/latest/admin/cleaning.html>`__ for more
31+
details.
