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
