Set Advanced Power Capping Policy

Before You Begin

  • Oracle ILOM SP firmware version 3.1.1 or later is required.

  • The Power Limit (power_limit) property must be set on the server prior to setting the Power Capping Policy. For details, see Set SP Power Target Limit Properties.

  • The Admin (a) role is required in Oracle ILOM to modify the Advanced Power Capping Policy properties.


Note - An overly aggressive Soft Power Capping Policy might produce an excessive amount of ILOM log entries that are related to assertion and deassertion of the power budget status (/SYS/PWRBS) sensor. To reduce these log entries shown in the ILOM log file, consider increasing the properties for either the Power Target Limit or Soft Cap Policy, or both.

This procedure provides both web and CLI SP instructions.

  • To set the SP Power Capping Policy, perform one of the following Oracle ILOM interface procedures:
    Oracle ILOM Interface
    Set Power Capping Policy (Soft Cap, Hard Cap, and Violation Actions) Procedure
    Web
    1. Click Power Management > Power Limit.

    2. Enable one of the following Advanced Power Capping Policy options:

      Soft Cap (default) - When enabled, the system power is capped only if the system power consumption (Actual power) exceeds the target power limit and the user-configurable grace period (default, 10 seconds).

      System administrators can choose to accept the default grace period of 10 seconds or modify the default grace period by clicking Custom and entering the allowable grace period seconds (1 to 99999).

      - or -

      Hard Cap – When enabled, the system power consumption is capped to keep the Peak Permitted Power under the target power limit.

    3. Enable one of the following Policy Violation Actions:

      None (default) – When enabled, no action is taken when the system power consumption violates the Power Policy.

      - or -

      Hard Power Off – When enabled, the system is immediately powered off when the system power consumption violates the Power Policy.

    4. Click Save to apply the changes.

    CLI
    1. To set a Soft Cap or Hard Cap value for the Power Capping Policy type:

      set /SP/powermgmt/budget pendingtimelimit=default|integer between 1 and 99999|0 commit_pending=true

      Where:

      default or integer between 1 and 99999 is a Soft Cap value – The power capping policy is set to Soft Cap by default with a default time limit of 10 seconds. When a Soft Cap value is set (default or 1 to 99999), the system power is capped only if the system power consumption (Actual power) exceeds the target power limit and the user-configurable timelimit property (default, 10 seconds).

      - or -

      0 is a Hard Cap value – When set to 0, the system power consumption is capped to keep the Peak Permitted Power under the target power limit.

    2. To set a value for violation_actions, type:

      set /SP/powermgmt/budget pendingviolation_actions=none|hardpoweroff commit_pending=true

      Where:

      none|hardpoweroff – Type none for the system to take no action if the power policy is violated.Type hardpoweroff to immediately power off the system if the system power consumption violates the power policy.
