Configuring Power Budget and Redundancy Using RACADM
NOTE: To perform power management actions, you must have Chassis Configuration Administrator privilege.
To enable and set the redundancy policy:
1. Open a serial/Telnet/SSH text console to CMC and log in.
2. Set properties as needed:
• To select a redundancy policy, type:
racadm config -g cfgChassisPower -o
cfgChassisRedundancyPolicy <value>
where <value> is 0 (No Redundancy), 1 (Grid Redundancy), 2 (Power Supply Redundancy). The default is 0.
For example, the following command enables Grid Redundancy mode:
racadm config -g cfgChassisPower -o cfgChassisRedundancyPolicy 1
• To enable or disable Extended Power Performance mode, type:
racadm config -g cfgChassisPower -o cfgChassisEPPEnable <value>
where <value> is 0 (disable), 1 (enable). The default is 1 for 3000 W PSUs
• To set the System Input Power Cap value, type:
racadm config -g cfgChassisPower -o cfgChassisPowerCap <value>
where <value> is a number between 2715–16685 representing the maximum power limit in Watts. The default is 16685.
For example, the following command sets the System Input Power Cap to 5400 watts:
racadm config -g cfgChassisPower -o cfgChassisPowerCap 5400
.
• To enable or disable dynamic PSU engagement, type:
racadm config -g cfgChassisPower -o cfgChassisDynamicPSUEngagementEnable <value>
where <value> is 0 (disable), 1 (enable). The default is 0.
For example, the following command disables dynamic PSU engagement:
racadm config -g cfgChassisPower -o cfgChassisDynamicPSUEngagementEnable 0
.
• To enable the Max Power Conservation Mode, type:
racadm config -g cfgChassisPower -o cfgChassisMaxPowerConservationMode 1
• To restore normal operation, type:
racadm config -g cfgChassisPower -o cfgChassisMaxPowerConservationMode 0
• Enable 110 VAC PSUs:
racadm config -g cfgChassisPower -o cfgChassisAllow110VACOperation 1
• Enable Server Performance Over Power Redundancy:
racadm config -g cfgChassisPower -o cfgChassisPerformanceOverRedundancy 1
• Disable Server Performance Over Power Redundancy:
racadm config -g cfgChassisPower -o cfgChassisPerformanceOverRedundancy 0
• To enable the power remote logging feature, type the following command:
racadm config -g cfgRemoteHosts -o cfgRhostsSyslogPowerLoggingEnabled 1
• To specify the desired logging interval, type the following command:
racadm config -g cfgRemoteHosts -o cfgRhostsSyslogPowerLoggingInterval n
where n is 1-1440 minutes.
• To determine if the power remote logging feature is enabled, type the following command:
racadm getconfig -g cfgRemoteHosts -o cfgRhostsSyslogPowerLoggingEnabled
