DRAC Power Driver for Ironic¶
https://blueprints.launchpad.net/ironic/+spec/drac-power-driver
The proposal presents the work required to add support for power management features for Dell Remote Access Controller in Ironic.
Problem description¶
Dell Remote Access Controller is an interface card from Dell offering a remote system management. This proposal adds the power management capabilities for DRAC.
Proposed change¶
Adding a new DracDriver to the list of available drivers in Ironic and
implementing the DracPower module to interact with WS-Management API “(WS-Man)”
described in the DCIM Base Server and Physical Asset Profile using the
python binding of the OpenWSMAN library.
Alternatives¶
There are other ways to interact with WS-Management endpoints but they are wrappers around OpenWSMAN command-line client. These are:
Data model impact¶
None
REST API impact¶
None
Driver API impact¶
None
Nova driver impact¶
None
Security impact¶
Admin credentials will be stored unencrypted in the DB and they will be visible in the driver_info field of the node when a node-show is issued.
Other end user impact¶
- The following driver_info fields are required:
drac_host: hostname or IP of the WS-Man endpoint
drac_port: port of the WS-Man endpoint (default value is 443, assuming the user configured the endpoint in secure mode)
drac_path: path of the WS-Man endpoint (default value is ‘/wsman’)
drac_protocol: protocol of the WS-Man endpoint (default value is ‘https’, assuming the user configured the endpoint in secure mode)
drac_username: username for the WS-Man endpoint
drac_password: password for the WS-Man endpoint
Scalability impact¶
None
Performance Impact¶
None
Other deployer impact¶
None
Developer impact¶
None

Work Items¶
Add DracDriver
Implement DracPower module for the DracDriver
Dependencies¶
This feature depends on the python binding of the OpenWSMAN library. It’s released under a simplified BSD licence and is available as a supported package in Ubuntu and Red Hat repositories.
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¶
The required driver_info properties need be included in the documentation to instruct operators how to use Ironic with DRAC.
