15 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). Therefore, 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 18.
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, the EPR banner is displayed at the group level. However, the EPR option may fail on other devices within the group due to connectivity issues or license expiry and so on. Therefore, use the EPR audit logs for successful and failure scenarios for all devices of the group.
Why is Power Manager not listed on Console and plugins page? Cause: Power Manager may not be listed due to the following reasons: ● The offline share folder is not accessible. ● Power Manager plugin and tar folder.s are not present in the offline share folder. ● If the plugin catalog file is edited, then the signature files can 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 do I not see temperature metric for some devices? Cause: The temperature metric is not visible for devices if they are powered off. 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. Likewise, when you clear a child group the selection gets cleared at the main group level.
Why can I not clear the checkbox for policies? Cause: The checkbox for policies in the Power Policies page is disabled if that policy is being enabled, disabled, or edited. After the job is completed, you can clear the policy. 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 the Delete Power Manager data option available in the Power Manager Preferences section.
16 Troubleshooting Data purge interval not reset Scenario: After reinstalling or updating to the latest version of Power Manager, the data purge interval is not reset to the default value.
Why is OpenManage Enterprise unresponsive when I try to perform plugin lifecycle-related actions (install/uninstall/ enable/disable)? Scenario: After rebooting OpenManage Enterprise appliance, if you try to perform any plugin lifecycle-related actions for Power Manager, the job is initiated in the back-end but you still see the Console and Plugins or Console and Extensions page.
Resolution: When there are updates to the static group membership through OpenManage Enterprise, there are multiple entries of this update in the Audit Logs and Alert Log. All options for managing physical groups are not displayed Scenario: After creating a physical group, you may not see Create New Physical Group, Edit Group, Manage Rack, Delete Group, or Attributes options when you click more options. Resolution: As a workaround, wait for some time or refresh the page, and then click more options.
