ironic.drivers.modules.pxe.PXEBoot
iRMC PXE boot.
-
clean_up_instance
(task)[source]¶ Cleans up the boot of instance.
This method cleans up the environment that was setup for booting the instance. It unlinks the instance kernel/ramdisk in node’s directory in tftproot and removes the PXE config.
- Parameters
task – a task from TaskManager.
- Raises
IRMCOperationError, if some operation on iRMC failed.
- Returns
None
-
prepare_instance
(task)[source]¶ Prepares the boot of instance.
This method prepares the boot of the instance after reading relevant information from the node’s instance_info. In case of netboot, it updates the dhcp entries and switches the PXE config. In case of localboot, it cleans up the PXE config.
- Parameters
task – a task from TaskManager.
- Returns
None
- Raises
IRMCOperationError, if some operation on iRMC failed.
-
prepare_ramdisk
(task, ramdisk_params)[source]¶ Prepares the boot of Ironic ramdisk using PXE.
This method prepares the boot of the deploy kernel/ramdisk after reading relevant information from the node’s driver_info and instance_info.
- Parameters
task – a task from TaskManager.
ramdisk_params – the parameters to be passed to the ramdisk. pxe driver passes these parameters as kernel command-line arguments.
- Returns
None
- Raises
MissingParameterValue, if some information is missing in node’s driver_info or instance_info.
- Raises
InvalidParameterValue, if some information provided is invalid.
- Raises
IronicException, if some power or set boot device operation failed on the node.

IRMCVirtualMediaBoot
[source]¶ Bases:
ironic.drivers.base.BootInterface
,ironic.drivers.modules.irmc.boot.IRMCVolumeBootMixIn
iRMC Virtual Media boot-related actions.
-
capabilities
= ['iscsi_volume_boot', 'fibre_channel_volume_boot']¶
-
clean_up_instance
(task)[source]¶ Cleans up the boot of instance.
This method cleans up the environment that was setup for booting the instance.
- Parameters
task – a task from TaskManager.
- Returns
None
- Raises
IRMCOperationError if iRMC operation failed.
-
clean_up_ramdisk
(task)[source]¶ Cleans up the boot of ironic ramdisk.
This method cleans up the environment that was setup for booting the deploy or rescue ramdisk.
- Parameters
task – a task from TaskManager.
- Returns
None
- Raises
IRMCOperationError if iRMC operation failed.
-
get_properties
()[source]¶ Return the properties of the interface.
- Returns
dictionary of <property name>:<property description> entries.
-
prepare_instance
(task)[source]¶ Prepares the boot of instance.
This method prepares the boot of the instance after reading relevant information from the node’s database.
- Parameters
task – a task from TaskManager.
- Returns
None
-
prepare_ramdisk
(task, ramdisk_params)[source]¶ Prepares the deploy or rescue ramdisk using virtual media.
Prepares the options for the deploy or rescue ramdisk, sets the node to boot from virtual media cdrom.
- Parameters
task – a TaskManager instance containing the node to act on.
ramdisk_params – the options to be passed to the ramdisk.
- Raises
ImageRefValidationFailed if no image service can handle specified href.
- Raises
ImageCreationFailed, if it failed while creating the floppy image.
- Raises
InvalidParameterValue if the validation of the PowerInterface or ManagementInterface fails.
- Raises
IRMCOperationError, if some operation on iRMC fails.
-
supported
= False¶
-
validate
(task)[source]¶ Validate the deployment information for the task’s node.
- Parameters
task – a TaskManager instance containing the node to act on.
- Raises
InvalidParameterValue, if config option has invalid value.
- Raises
IRMCSharedFileSystemNotMounted, if shared file system is not mounted.
- Raises
InvalidParameterValue, if some information is invalid.
- Raises
MissingParameterValue if ‘kernel_id’ and ‘ramdisk_id’ are missing in the Glance image, or if ‘kernel’ and ‘ramdisk’ are missing in the Non Glance image.
-
validate_rescue
(task)[source]¶ Validate that the node has required properties for rescue.
- Parameters
task – a TaskManager instance with the node being checked
- Raises
MissingParameterValue if node is missing one or more required parameters
- Raises
InvalidParameterValue, if any of the parameters have invalid value.
-

IRMCVolumeBootMixIn
[source]¶ Bases:
object
Mix-in class for volume boot configuration to iRMC
iRMC has a feature to set up remote boot to a server. This feature can be used by VIOM (Virtual I/O Manager) library of SCCI client.

attach_boot_iso_if_needed
(task)[source]¶ Attaches boot ISO for a deployed node if it exists.
This method checks the instance info of the bare metal node for a boot ISO. If the instance info has a value of key ‘irmc_boot_iso’, it indicates that ‘boot_option’ is ‘netboot’. Threfore it attaches the boot ISO on the bare metal node and then sets the node to boot from virtual media cdrom.
- Parameters
task – a TaskManager instance containing the node to act on.
- Raises
IRMCOperationError if attaching virtual media failed.
- Raises
InvalidParameterValue if the validation of the ManagementInterface fails.
Check if Share File System (NFS or CIFS) is mounted.
- Raises
InvalidParameterValue, if config option has invalid value.
- Raises
IRMCSharedFileSystemNotMounted, if shared file system is not mounted.
