Built-in hardware managers

GenericHardwareManager

This is the default hardware manager for ironic-python-agent. It provides support for hardware-inventory and the default deploy and clean steps.

deploy.write_image(node, ports, image_info, configdrive=None): A deploy step backing the write_image deploy step of the direct deploy interface <admin/interfaces/deploy.html#direct-deploy>. Should not be used explicitly, but can be overridden to provide a custom way of writing an image.
deploy.erase_device_metadata(node, ports): Erases partition tables from all recognized disk devices. Can be used with software RAID since it requires empty holder disks.
raid.apply_configuration(node, ports, raid_config, delete_existing=True): Apply a software RAID configuration. It belongs to the raid interface and must be used through the ironic RAID feature <admin/raid.html>.

deploy.erase_devices: Securely erases all information from all recognized disk devices. Relatively fast when secure ATA erase is available, otherwise can take hours, especially on a virtual environment. Enabled by default.
deploy.erase_device_metadata: Erases partition tables from all recognized disk devices. Can be used as an alternative to the much longer erase_devices step.
raid.create_configuration: Create a RAID configuration. This step belongs to the raid interface and must be used through the ironic RAID feature <admin/raid.html>.
raid.delete_configuration: Delete the RAID configuration. This step belongs to the raid interface and must be used through the ironic RAID feature <admin/raid.html>.
