DRAC Management driver for Ironic

https://blueprints.launchpad.net/ironic/+spec/drac-management-driver

The proposal presents the work required to add support for boot management features for Dell Remote Access Controllers.

Problem description

Dell Remote Access Controller is an interface card from Dell offering remote system management. This proposal adds the boot management capabilities for DRAC.

Proposed change

  • Create a DracManagement class and implement the following methods interacting with the WS-Management API “(WS-Man)” described in the DCIM BIOS and Boot Management Profile using the python binding of the OpenWSMAN library:

    • set_boot_device() - To set the boot device for a node. The persistent

      flag will be supported to indicate if the change should be applied for the next boot only, or persistently.

    • get_boot_device() - To get the current boot device of a node with the

      indication whether it’s persistent, or not.

    • get_supported_boot_devices() - To get a list of the supported boot

      devices of a node. The supported boot devices will be disk and pxe.

  • Add DracPXEDriver class to the list of the available drivers, which uses the PXEDeploy, DracPower, and DracManagement interfaces. (The above change is a prerequisite for this one, because PXE requires setting the boot device to network).

Work Items

  • Add methods supporting boot management to the management interface.

  • Create the DracPXEDriver class.

Dependencies

  • This feature depends on the python binding of the OpenWSMAN library which was introduced by the power management interface of the DRAC driver.

  • This feature requires 11th or 12th generation of Dell PowerEdge servers.

Testing

  • Unit tests

  • 3rd-party CI: we would like to do it for this driver, but do not have sufficient hardware available at this time.

Documentation Impact

None
