16 Frequently Asked Questions Why am I not able to view the metrics? Cause: After removing the required iDRAC or DC License, or the OpenManage Enterprise Advanced Feature license, the license-dependent features are not available on the User Interface (UI). Hence, the metric is not available, and the values are not collected by Power Manager from the next inventory cycle.
Why do I not see all metric types for different types of devices? Cause: Different devices support different types of metrics. Table 15.
Why do I see a failure of EPR in audit log but EPR is applied successfully for the group? Cause: When EPR option is applied for a group, and if the EPR option is applied successfully for at least one device in the group, we can see the EPR banner at the group level. However, the EPR option may fail on other devices of the group due to connectivity issues or license expiry and so on. Hence, there are EPR audit logs for successful and failure scenarios for all devices of the group.
Why is Power Manager not listed on Console and Extensions page? Cause: Power Manager may not be listed due to the following reasons: ● The offline share folder is not accessible. ● Power Manager extension and tar folder.s are not present in the offline share folder ● If the extension catalog file is edited, then the signature files get corrupted. Resolution: Ensure that the offline share folder is reachable through OpenManage Enterprise with the following files: ● ome_powermanager_1.0.0.tar.
Why can I not select a particular child group? Cause: When you select a group, all the child groups within this group are also selected. But when you clear a child group the selection gets cleared at the main group level also.
How do I see the old metric data? Cause: The old metric data is not available after a few days because the data is deleted. This configuration depends on the selection of Delete Power Manager data option available in Power Manager Preferences section. Why are the values I set using threshold REST API not configured? Cause: If you use threshold REST API before installing and adding the devices to Power Manager, the values are not retained.
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.
For an MX7000 chassis, the power cap value is displayed as same as the upper bound value. When you manually change the power cap percentage, the value is not updated and even if you change the value, the percentage is not updated. Resolution: Provide the power cap value, and save the policy. The policy imposes the specified power cap value on the selected devices or groups.
Resolution: Create an alert policy by selecting the group for which you want to ignore the alerts by selecting the Ignore option in Create Alert Policy wizard. 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.
