|
|
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.
