Appendix B. Power Management Drivers

Although IPMI is the main method the director uses for power management control, the director also supports other power management types. This appendix contains a list of the power management features that the director supports. Use these power management settings for Section 6.1, “Registering Nodes for the Overcloud”.

B.1. Intelligent Platform Management Interface (IPMI)

The standard power management method using a baseboard management controller (BMC).

pm_type
Set this option to ipmi.
pm_user; pm_password
The IPMI username and password.
pm_addr
The IP address of the IPMI controller.
pm_port (Optional)
The port to connect to the IPMI controller.

B.2. Redfish

A standard RESTful API for IT infrastructure developed by the Distributed Management Task Force (DMTF)

pm_type
Set this option to redfish.
pm_user; pm_password
The Redfish username and password.
pm_addr
The IP address of the Redfish controller.
pm_system_id
The canonical path to the system resource. This path must include the root service, version, and the path/unqiue ID for the system. For example: /redfish/v1/Systems/CX34R87.

B.3. Dell Remote Access Controller (DRAC)

DRAC is an interface that provides out-of-band remote management features including power management and server monitoring.

pm_type
Set this option to idrac.
pm_user; pm_password
The DRAC username and password.
pm_addr
The IP address of the DRAC host.

B.4. Integrated Lights-Out (iLO)

iLO from Hewlett-Packard is an interface that provides out-of-band remote management features including power management and server monitoring.

pm_type
Set this option to ilo.
pm_user; pm_password
The iLO username and password.
pm_addr

The IP address of the iLO interface.

  • To enable this driver, add ilo to the enabled_hardware_types option in your undercloud.conf and rerun openstack undercloud install.
  • The director also requires an additional set of utilities for iLo. Install the python-proliantutils package and restart the openstack-ironic-conductor service:

    $ sudo yum install python-proliantutils
    $ sudo systemctl restart openstack-ironic-conductor.service
  • HP nodes must have a minimum ILO firmware version of 1.85 (May 13 2015) for successful introspection. The director has been successfully tested with nodes using this ILO firmware version.
  • Using a shared iLO port is not supported.

B.5. Cisco Unified Computing System (UCS)

UCS from Cisco is a data center platform that combines compute, network, storage access, and virtualization resources. This driver focuses on the power management for bare metal systems connected to the UCS.

pm_type
Set this option to cisco-ucs-managed.
pm_user; pm_password
The UCS username and password.
pm_addr
The IP address of the UCS interface.
pm_service_profile

The UCS service profile to use. Usually takes the format of org-root/ls-[service_profile_name]. For example:

"pm_service_profile": "org-root/ls-Nova-1"
  • To enable this driver, add cisco-ucs-managed to the enabled_hardware_types option in your undercloud.conf and rerun the openstack undercloud install command.
  • The director also requires an additional set of utilities for UCS. Install the python-UcsSdk package and restart the openstack-ironic-conductor service:

    $ sudo yum install python-UcsSdk
    $ sudo systemctl restart openstack-ironic-conductor.service

B.6. Fujitsu Integrated Remote Management Controller (iRMC)

Fujitsu’s iRMC is a Baseboard Management Controller (BMC) with integrated LAN connection and extended functionality. This driver focuses on the power management for bare metal systems connected to the iRMC.

Important

iRMC S4 or higher is required.

pm_type
Set this option to irmc.
pm_user; pm_password
The username and password for the iRMC interface.
pm_addr
The IP address of the iRMC interface.
pm_port (Optional)
The port to use for iRMC operations. The default is 443.
pm_auth_method (Optional)
The authentication method for iRMC operations. Use either basic or digest. The default is basic
pm_client_timeout (Optional)
Timeout (in seconds) for iRMC operations. The default is 60 seconds.
pm_sensor_method (Optional)

Sensor data retrieval method. Use either ipmitool or scci. The default is ipmitool.

  • To enable this driver, add irmc to the enabled_hardware_types option in your undercloud.conf and rerun the openstack undercloud install command.
  • If you enable SCCI as the sensor method, you must also install an additional set of utilities. Install the python-scciclient package and restart the openstack-ironic-conductor service:

    $ yum install python-scciclient
    $ sudo systemctl restart openstack-ironic-conductor.service

B.7. Red Hat Virtualization

This driver provides control over virtual machines in Red Hat Virtualization through its RESTful API.

pm_type
Set this option to staging-ovirt.
pm_user; pm_password
The username and password for your Red Hat Virtualization environment. The username also includes the authentication provider. For example: admin@internal.
pm_addr
The IP address of the Red Hat Virtualization REST API.
pm_vm_name
The name of the virtual machine to control.
mac

A list of MAC addresses for the network interfaces on the node. Use only the MAC address for the Provisioning NIC of each system.

  • To enable this driver, add staging-ovirt to the enabled_hardware_types option in your undercloud.conf and rerun the openstack undercloud install command.

B.8. Manual Management

Use the ‘manual-management’ driver to control bare metal devices that do not have power management. The director does not control the registered bare metal devices, and you must perform manual power operations at certain points in the introspection and deployment processes.

Important

This option is only available for testing and evaluation purposes. It is not recommended for Red Hat OpenStack Platform enterprise environments.

pm_type

Set this option to manual-management.

  • This driver does not use any authentication details because it does not control power management.
  • To enable this driver, add manual-management to the enabled_hardware_types option in your undercloud.conf and rerun the openstack undercloud install command.
  • When performing introspection on nodes, manually start the nodes after running the openstack overcloud node introspect command.
  • When performing overcloud deployment, check the node status with the ironic node-list command. Wait until the node status changes from deploying to deploy wait-callback and then manually start the nodes.
  • After the overcloud provisioning process completes, reboot the nodes. To check the completion of provisioning, check the node status with the ironic node-list command, wait until the node status changes to active, then manually reboot all overcloud nodes.
