Selecting the check box to enable Max Power Conservation Mode (MPCM), displays the following message:
Enabling Max Power Conservation Mode option will force servers into a low power,
limited performance mode and disable server power up. Press OK to continue.
Scenario 3: The EPP option is grayed out and not available for selection, if:
EPP is disabled with 3000W PSUs, and any of the following power settings is enabled:
Server Based Power Management (SBPM)
Redundancy Policy: Power Supply Redundancy or No Redundancy
Max Power Conservation Mode (MPCM).
Dynamic Power Supply Engagement (DPSE).
System Input Power Cap is set to value less than or equal to 13300W or (45381 BTU/h) .
The chassis does not have six 3000W PSUs or all the PSUs do not support EPP , the EPP option is grayed out and not
available for selection.
Extended Power Performance Scenarios - Using
RACADM
Scenario 1: Managing EPP feature control (enable/disable) using racadm getconfig/config set commands
To enable EPP feature on a 3000W AC PSU configuration, use:
racadm config -g cfgChassisPower -o cfgChassisEPPEnable 1
To disable EPP feature on a 3000W AC PSU configuration, use:
To disable EPP feature on a 3000W AC PSU configuration, use:
To verify if the EPP feature is enabled on a 3000W AC PSU configuration, use:
racadm getconfig -g cfgChassisPower -o cfgChassisEPPEnable
Scenario 2: Viewing EPP feature status using racadm getpbinfo:
racadm getpbinfo
Extended Power Performance(EPP) Status = Enabled (inactive)
Available Power in EPP Pool = 3167 W (10806 BTU/h)
Used Power in EPP Pool = 0 W (0 BTU/h)
EPP Percent - Available = 100.0
Scenario 3: Viewing EPP feature control operations recorded in CMC logs:
racadm getraclog
Jul 31 14:16:11 CMC-4C2WXF1 Log Cleared
Jul 31 14:15:49 CMC-4C2WXF1 Extended Power Performance is Enabled
Jul 31 14:15:49 CMC-4C2WXF1 Extended Power Performance is Disabled
Scenario 4: Changing Power configuration properties that are incompatible with EPP, when EPP is enabled:
Enabling Server Based Power Mangement (SBMP) on a 3000W AC PSU
racadm config -g cfgChassisPower -o cfgChassisServerBasedPowerMgmtMode 1
This feature is not supported while Extended Power Performance is enabled.
Enabling Dynamic Power Supply Engagement on a 3000W AC PSU
racadm config -g cfgChassisPower -o cfgChassisDynamicPSUEngagementEnable 1
This feature is not supported while Extended Power Performance is enabled.
Changing Power Redundancy Policy from Grid Redundancy Policy to PSU Redundancy Policy on a 3000W AC PSU
racadm config -g cfgChassisPower -o cfgChassisRedundancyPolicy 2
This feature is not supported while Extended Power Performance is enabled.
