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.
