Resolution: The chassis is added to the group at the back-end, but the GUI times out before the chassis responds to
OpenManager Power Center.
In the compare report, why is the average power value of a
device different when the service is stopped for a few
hours?
Possible Cause: There may be an inconsistency in the logic for All Devices and Managed Groups.
Resolution: You can select the device from the Managed Groups where the power value calculation is more accurate.
Why is the “policy return to normal” event not displayed
when the only device in the Chassis Management Controller
(CMC) is deleted?
Possible Cause: When the last blade in the chassis is deleted, the power value returns to “–1” as there is no device in the
chassis. The comparison between the power value and the policy capping fails and the “policy return to normal” event is not
triggered.
Resolution: You can add a blade to the chassis if the power value does not exceed the power capping value. The “policy return
to normal” event is triggered. You can delete the events manually.
After discovering the devices, incorrect device information
is displayed? Why is this happening?
Possible Cause: It may be due to the IPMI privilege level limit set to operator/user level in iDRAC.
Resolution: Ensure that in the iDRAC page, the channel privilege level limit in the IPMI settings section is set to Administrator.
I am not able to view the power headroom graph on the
home screen. How do I troubleshoot?
Scenario 1
Possible Cause: The Estimated Max Power for some unsupported devices is not available.
Resolution: Configure the Estimated Max Power and then view the graph.
Scenario 2
Possible Cause: The peak power of a group is not available.
Resolution: Add devices to the group and assign power before viewing the graph.
Scenario 3
Possible Cause: The Power Capacity of the group is not available.
Resolution: Configure the power capacity of the group or add rack (for which the power capacity is mandatory) in a group, so
that the power capacity of the group can be calculated from the power capacity of the racks in that particular group.
Scenario 4
Possible Cause: The monitored peak power of the group is higher than the power capacity of the group.
Resolution: Configure the power capacity of the group or the racks in the group.
