31 Emergency Power Reduction (EPR) feature with OpenManage Enterprise Power Manager
What happens to the EPR applied on individual device level (EPR1) when the same device is added to
a static group monitored in Power Manager and another EPR (EPR 2) is already applied or applied
later on group level?
Description:
EPR applied at group level is not effective on the device, when the added device already has an EPR applied
on it.
For example, consider the following scenario:
1. Add two Power Manager capable devices (Device1, Device2) into Power Manager.
2. Create a Static Group (SG1) with Device2 in OpenManage Enterprise and add the group in Power
Manager Monitoring List.
3. Apply EPR1 on Device1.
4. Apply EPR2 on the Static Group (SG1) with Device2. EPR is applied on Device2.
5. Add Device1 with an active EPR (EPR1) to the Static Group with active EPR2.
Results:
Addition of Device2 is successful to the Custom Group. EPR2 applied in Group level is effective on Device2,
whereas the EPR1 is in control of Device1. Same is the behavior even if EPR is applied later to the Static
Group (SG1) after adding Device1 with EPR1.
What happens when a device with EPR Throttle (EPR1) applied is added to a static group and later an
EPR Shutdown (EPR2) is applied on the static group?
Description:
EPR applied on group level is not effective on the device when the device added to the static group already
has an active EPR.
For example, consider the following scenario:
1. Discover and add two Power Manager capable devices (Device1, Device2) into Power Manager.
2. Create a Static Group (SG1) with Device2 in OpenManage Enterprise and add the group in Power
Manager.
3. Apply EPR Throttle (EPR1) on Device1.
4. Add Device1 with an active EPR Throttle (EPR1) to the Static Group. The group now contains
Device1 and Device2.
5. Apply EPR Shutdown (EPR2) on the Static Group (SG1).
Results:
EPR2 (EPR Shutdown) applied on group level is applied only on Device2. EPR shutdown action will fail in
Device1 with following audit log entry:
Message ID—CPWR0023, Severity—Warning, Category—Configuration
Unable to enable the Emergency Power Reduction feature on the target <Device1> because the feature is
already enabled on the target.
