Violation Actions
|
The Violation Actions property enables you to specify the settings you want ILOM to take if the power limit cannot be achieved within the set grace period.
You can choose to specify one of the following actions:
- None - If you enable this option and the power limit cannot be achieved, ILOM will display a Status Error Message to notify you that ILOM is unable to achieve the power capping limit specified.
or

Before You Begin
- Review the Power Monitoring Terminology defined in the Oracle Integrated Lights Out Manager (ILOM) 3.0 Concepts Guide.
- Review the conceptual information about power supply redundancy for CMM systems in the Oracle Integrated Lights Out Manager (ILOM) 3.0 Concepts Guide.
- You must have ILOM 3.0.6 or later installed on your server to configure the CMM power supply redundancy properties.
- You must have Administrator (a) role privileges in ILOM to change any power management configuration variables.
View or Configure CMM Power Supply Redundancy Properties
|
1. Log in to the ILOM CMM web interface.
2. In the left pane of the CMM web interface, select CMM then in the right pane of the web interface page, select the Power Management --> Redundancy tabs.
The Power Management Redundancy page appears.
3. In the Redundancy page, view or configure the properties.:
- Power Supply Redundancy Policy - Select the number of power supplies to allocate for redundancy.
- None - To reserve no power supplies.
- N+N - To reserve half of the power supplies.
| Note - When you change the redundancy policy, this change affects the amount of power the CMM is permitted to allocate to server modules (blades). The chassis Permitted Power is set to the power that the available power supplies can provide minus the redundant power available. In addition, when there is no redundant power available to the system, a loss of a power supply will cause the system to reduce the Permitted Power. If the system reduces the Permitted Power below the power that had already been allocated, you should immediately take steps to turn off the server modules to reduce the allocated power.
|
- Redundant Power - This value is provided by the system. It represents the available power that is not allocated.
