9 Managing power policies A power policy contains a variety of settings that help in regulating the power consumption for a specific device or a group. A policy is useful for power management in different situations. For example, you can create a policy to: ● Power Cap—Ensure that power consumption does not exceed the capacity of the circuit. ● Control Power Usage—Schedule power usage according to the workload of the device or group.
● If the device is PowerEdge VRTX or PowerEdge FX2 chassis, they have a Chassis Management Controller (CMC) Enterprise license To create a power policy in Power Manager, perform the following steps: 1. From OpenManage Enterprise, click Power Management > Power Policies. The Power Policies tab is displayed. 2. Click Create. The Create Power Policy wizard is displayed. 3. Provide a policy name and a description and click Next. To enable the policy after creation, Enable option is selected by default. 4.
Editing policy Based on the power history of the selected devices or groups, update the power cap value in a policy. NOTE: You cannot edit the selection of a device or group. To edit a policy, perform the following steps: 1. From OpenManage Enterprise, click Power Management > Power Policies. The Power Policies tab is displayed. 2. Select a policy that you want to edit and click Edit. The power policy wizard is displayed. 3. To save the changes made, click Finish. The changes are saved successfully.
10 Managing Emergency Power Reduction Emergency Power Reduction (EPR) feature helps reduce power consumption of devices immediately during a power emergency. For example, a power failure and your devices are running on UPS, you can initiate EPR to reduce the power consumption of your managed devices. NOTE: Applying EPR on the devices, throttles down the power to an extremely low level, which impacts performance, or shuts them down completely.
Disabling Emergency Power Reduction To bring back the devices or devices that are part of a group to their normal mode, disable the Emergency Power Reduction (EPR) To disable the EPR, perform the following steps: 1. From OpenManage Enterprise, click Power Management > Emergency Power Reduction. 2. Select the devices or groups for which you want to disable EPR, and click Disable. In the confirmation page, click Yes. EPR is disabled successfully.
11 Thresholds Thresholds enable you to specify warning and critical limits for power and temperature metrics on devices and groups. Power Manager generates alerts through OpenManage Enterprise if the configured limits are violated and you are notified of the violations. The status of power and temperature are displayed in form of graphs on the Metrics or Group Details tab.
Viewing Alert Thresholds View the status of the device or group based on the configured alert thresholds. Ensure that you add devices or groups to Power Manager. To view the alert thresholds graphs for power and temperature: 1. From OpenManage Enterprise, perform one of the following steps: ● For device: a. Click Devices. All the devices that are discovered in OpenManage Enterprise are displayed. b. From the list of devices, select a device name. The details of the device are displayed on the Overview page.
Deleting Alert Thresholds To remove the thresholds that are configured on devices or groups, clear all the thresholds. To delete alert thresholds, perform the following steps: 1. From OpenManage Enterprise, perform one of the following steps: ● For device: a. Click Devices. All the devices that are discovered in OpenManage Enterprise are displayed. b. From the list of devices, select a device name. The details of the device are displayed on the Overview page. c.
12 Alerts An alert is helpful during monitoring thresholds when you want a notification about when the power of a device or a group exceeds the limits set on them. Also, when there are changes to a group you are monitoring.
13 Scalability and performance Power Manager supports up to 3000 target devices in one data center. It is important to configure appropriate Power and Temperature Sampling Intervals in Power Manager, because sampling intervals impact the system performance and footprint significantly, including network bandwidth consumption, database size, and trend graph display latency. The default power and temperature intervals in Power Manager are 15 minutes.
14 Widgets for Power Manager Widgets enable you to have quick access to selected groups to view their power and thermal history. Also, view the maximum energy consumers regarding a server, chassis, and group.
15 Reports in Power Manager Reports contain information about the specific devices or devices part of a group, jobs, alerts, and other elements of your data center. Reports are built-in, and user-defined. The built-in reports are downloaded in .HTML format. However, you can download the report in CSV, PDF, or .XLS format also.

16 Frequently Asked Questions Why do I see two entries with the same date in the graph when the time duration was chosen for showing the graph is changed? Cause: When viewing the Metrics and Monitoring History graphs for 3 months, 6 months, or 1 year the data is autoconverted from UTC time zone to your current time zone and displayed. And, due to the time zone differences, there are two entries for the same day on the graphs.
Table 9.
Why can I not install Power Manager? Cause: There are two cases in which the installation of Power Manager may fail: ● If you have selected the online updates option in OpenManage Enterprise, check for the connectivity for the online path is successful. ● If you have selected the offline updates option in OpenManage Enterprise, ensure that the ome_powermanager_1.0.0.tar.gz folder has all the files for extension catalog with the sign file and the extension installer packages, including the RPMs.
You can apply policies on supported PowerEdge servers with iDRAC Enterprise, PowerEdge FX2, FX2s, and VRTX chassis with CMC Enterprise license. NOTE: PowerEdge M1000e and PowerEdge MX7000 chassis do not require CMC Enterprise license.
Why are some of the fields in reports empty? Cause: The fields may be empty in a report due to the following reasons: ● When the device was not reachable for that duration. ● When that category is not applicable for that device. ● When the values are not defined for certain fields in Power Manager and these fields are part of the report.
17 Troubleshooting Why cannot I apply Emergency Power Reduction (EPR) on target device or a group? Scenario: When you are trying to apply EPR on a device, the EPR operation may fail and there is an entry in the Audit Logs. When you are trying to apply EPR option on a group, the EPR operation may fail with the following error message: Unable to enable the Emergency Power Reduction feature because target devices are unavailable in the group.
Power policy not updated after the changes Scenario: When the time span of an active policy is changed, the policy is not disabled on the device. Resolution: Resolve the issue using one of the following methods: ● Manually disable the policy on the device. ● Disable the policy in Power Manager, change the time span, and then enable the policy.
Policy not deactivated Scenario: When scheduling a power policy for a single day, the policy does not deactivate later. Resolution: To deactivate the policy perform one of the following actions: ● In Power Management > Power Policies page, select the policy and click Disable. ● In Power Management > Power Policies page, select the policy and click Edit.
