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 provides a list of the supported power management features. Use these power management settings for Section 5.1, “Registering Nodes for the Overcloud”.
B.1. 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
pxe_drac. - pm_user; pm_password
- The DRAC username and password.
- pm_addr
- The IP address of the DRAC host.
B.2. 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
pxe_ilo. - pm_user; pm_password
- The iLO username and password.
- pm_addr
The IP address of the iLO interface.
-
Edit the
/etc/ironic/ironic.conffile and addpxe_iloto theenabled_driversoption to enable this driver. The director also requires an additional set of utilities for iLo. Install the
python-proliantutilspackage and restart theopenstack-ironic-conductorservice:sudo yum install python-proliantutils sudo systemctl restart openstack-ironic-conductor.service
$ sudo yum install python-proliantutils $ sudo systemctl restart openstack-ironic-conductor.serviceCopy to Clipboard Copied! Toggle word wrap Toggle overflow - HP nodes must a 2015 firmware version for successful introspection. The director has been successfully tested with nodes using firmware version 1.85 (May 13 2015).
- Using a shared iLO port is not supported.

B.3. Cisco Unified Computing System (UCS)
UCS from Cisco is a data center platform that unites 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
pxe_ucs. - 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"
"pm_service_profile": "org-root/ls-Nova-1"Copy to Clipboard Copied! Toggle word wrap Toggle overflow -

B.4. 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.
iRMC S4 or higher is required.
- pm_type
-
Set this option to
pxe_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
basicordigest. The default isbasic - 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
ipmitoolorscci. The default isipmitool.-
Edit the
/etc/ironic/ironic.conffile and addpxe_irmcto theenabled_driversoption to enable this driver. The director also requires an additional set of utilities if you enabled SCCI as the sensor method. Install the
python-scciclientpackage and restart theopenstack-ironic-conductorservice:yum install python-scciclient sudo systemctl restart openstack-ironic-conductor.service

B.5. SSH and Virsh
The director can access a host running libvirt through SSH and use virtual machines as nodes. The director uses virsh to control the power management of these nodes.
This option is available for testing and evaluation purposes only. It is not recommended for Red Hat OpenStack Platform enterprise environments.
- pm_type
-
Set this option to
pxe_ssh. - pm_user; pm_password
The SSH username and contents of the SSH private key. If using the CLI tools to register your nodes, the private key must be on one line with new lines replaced with escape characters (
\n). For example:-----BEGIN RSA PRIVATE KEY-----\nMIIEogIBAAKCAQEA .... kk+WXt9Y=\n-----END RSA PRIVATE KEY-----
-----BEGIN RSA PRIVATE KEY-----\nMIIEogIBAAKCAQEA .... kk+WXt9Y=\n-----END RSA PRIVATE KEY-----Copy to Clipboard Copied! Toggle word wrap Toggle overflow Add the SSH public key to the libvirt server’s
authorized_keyscollection.- pm_addr
The IP address of the virsh host.
-
The server hosting libvirt requires an SSH key pair with the public key set as the
pm_passwordattribute. -
Ensure the chosen
pm_userhas full access to the libvirt environment.
-
The server hosting libvirt requires an SSH key pair with the public key set as the
B.6. Fake PXE Driver
This driver provides a method to use bare metal devices without power management. This means the director does not control the registered bare metal devices and as such require manual control of power at certain points in the introspect and deployment processes.
This option is available for testing and evaluation purposes only. It is not recommended for Red Hat OpenStack Platform enterprise environments.
- pm_type
Set this option to
fake_pxe.- This driver does not use any authentication details because it does not control power management.
Edit the
/etc/ironic/ironic.conffile and addfake_pxeto theenabled_driversoption to enable this driver. Restart the baremetal services after editing the file:sudo systemctl restart openstack-ironic-api openstack-ironic-conductor
$ sudo systemctl restart openstack-ironic-api openstack-ironic-conductorCopy to Clipboard Copied! Toggle word wrap Toggle overflow -
When performing introspection on nodes, manually power the nodes after running the
openstack baremetal introspection bulk startcommand. -
When performing overcloud deployment, check the node status with the
ironic node-listcommand. Wait until the node status changes fromdeployingtodeploy wait-callbackand then manually power 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-listcommand, wait until the node status changes toactive, then manually reboot all overcloud nodes.
