The ironic.drivers.modules.irmc.boot Module

iRMC Boot Driver

class ironic.drivers.modules.irmc.boot.IRMCPXEBoot[source]

Bases: ironic.drivers.modules.pxe.PXEBoot

iRMC PXE boot.

clean_up_instance(*args, **kwargs)[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(*args, **kwargs)[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(*args, **kwargs)[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.

class ironic.drivers.modules.irmc.boot.IRMCVirtualMediaBoot[source]

Bases: ironic.drivers.base.BootInterface, ironic.drivers.modules.irmc.boot.IRMCVolumeBootMixIn

iRMC Virtual Media boot-related actions.

clean_up_instance(*args, **kwargs)[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(*args, **kwargs)[source]

Cleans up the boot of ironic ramdisk.

This method cleans up the environment that was setup for booting the deploy ramdisk.

Parameters:task – a task from TaskManager.
Returns:None
Raises:IRMCOperationError if iRMC operation failed.
get_properties()[source]
prepare_instance(*args, **kwargs)[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(*args, **kwargs)[source]

Prepares the deploy ramdisk using virtual media.

Prepares the options for the deployment 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 deploy 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.

validate(*args, **kwargs)[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.
class ironic.drivers.modules.irmc.boot.IRMCVolumeBootMixIn[source]
