Power Management

You can power on, power off, and reboot clients using the Uyuni Web UI.

This feature uses the IPMI protocol and is managed using a Cobbler profile. The client must be IPMI-enabled, and configured to use a power management server. To use any power management functionality, IPMI configuration details must be added to Uyuni.

Navigate to Systems  Systems List, select the client you want to manage, and navigate to the Provisioning  Power Management tab. Complete the details for the power management server, and click the appropriate button for the action to take, or click Save only to save the details without taking any action.

You can apply power management actions to multiple clients at the same time by adding them to the system set manager. For more information about using the system set manager, see client-configuration:system-set-manager.adoc.

Power Management and Cobbler

The first time you use a power management feature, a Cobbler system record is automatically created, if one does not yet exist for the client. These automatically created system records are not bootable from the network, and include a reference to a dummy system image. This is needed because Cobbler does not currently support system records without profiles or images.

Cobbler power management uses fence-agent tools to support protocols other than IPMI. Only IPMI protocols are supported by Uyuni. You can configure your client to use other protocols by adding the fence-agent names as a comma-separated list to the java.power_management.types configuration parameter in the rhn.conf configuration files.
