Querying and Configuring Power Capping

Querying and Configuring Power Capping

This topic describes the Querying and Configuring Power Capping.

Scenarios

Query and configure power capping for the chassis and server nodes.

Prerequisites

Conditions

You have logged in to a server node. For details, see Logging In to a Server Over a Serial Port by Using PuTTY or Logging In to a Server Over a Network Port by Using PuTTY.

Data

Data preparation is not required for this operation.

Procedure

  1. Use PuTTY to log in to the management module.
  2. Run the following command to query the chassis power capping status:

    ipmcget -t powercapping -d info

    The command output is as follows:

    iBMC:/->ipmcget -t powercapping -d info 
    Shelf Power Capping Info: 
     Mode           : Manual 
     Enable         : Enabled 
     Value          : 1300W 
     Threshold      : 10% 
     Current Power  : 441W 
     
    Blades Power Capping Info: 
     Blade Presence  FailedAction  ManualState  CappingState  Setting(W)  LimitPower(W)  CurrentPower(W) 
     blade1  Presence  NoAction      enabled      enabled       600         157           100    
     blade2  Presence  PowerOff      disabled     enabled       153         106           84     
     blade3  Absence    
     blade4  Absence    
     blade5  Presence  PowerOff      disabled     enabled       153         73            12     
     blade6  Absence    
     blade7  Absence    
     blade8  Presence  PowerOff      disabled     enabled       153         0             12     
    NOTE:

    If a 4U4 node is installed, it occupies a slot with an even number and one with an odd number. Power capping data is displayed for the odd slot number, and Absence is displayed for the even slot number.

  3. Run the following command to set the chassis power capping threshold:

    ipmcset -t powercapping -d threshold -v <value>

    The following describes the parameter.

    Parameter

    Parameter Description

    Value

    value

    Chassis power capping threshold

    0 to the maximum threshold

    NOTE:

    The maximum threshold is a customized value.

    Example: # Set the chassis power capping threshold to 70.

    iBMC:/->ipmcset -t powercapping -d threshold -v 70 
    Set shelf power capping threshold successfully.     

  4. Run the following command to set the chassis power cap value:

    ipmcset -t powercapping -d shelfvalue -v <value>

    The following describes the parameter.

    Parameter

    Parameter Description

    Value

    value

    Chassis power cap value

    -

    NOTE:

    The chassis power cap value range depends on the minimum total power of server nodes and rated chassis power.

    Example: # Set the chassis power cap value to 1200.

    iBMC:/->ipmcset -t powercapping -d shelfvalue -v 1200 
    Set shelf power capping value successfully.     

  5. Run the following command to set the chassis power capping mode:

    ipmcset -t powercapping -d mode -v <option>

    The following describes the parameter:

    Parameter

    Parameter Description

    Value

    option

    Power capping mode

    • 0: equal mode.
    • 1: manual mode.
    • 2: proportional mode.

    Example: # Set the chassis power capping mode to the manual mode.

    iBMC:/->ipmcset -t powercapping -d mode -v 1 
    Set shelf power capping mode (manual) successfully.     

  6. (Optional) Run the following command to set the power cap value of a server node:

    ipmcset -t powercapping -d bladevalue -v<bladeid><value>

    The following describes the parameters:

    Parameter

    Parameter Description

    Value

    bladeid

    Server node ID

    1 to 8

    value

    Server node power cap value

    -

    NOTE:
    • Before setting the node power cap value, set the chassis power capping mode to the manual mode.
    • The server node power cap value range depends on the minimum power cap values of all present nodes and chassis power cap value.

    Example: # Set the power cap value of server node 1 to 160.

    iBMC:/->ipmcset -t powercapping -d bladevalue -v 1 160 
    Set blade power capping value successfully.     

  7. (Optional) Run the following command to set the action performed after node power capping fails:

    ipmcset -t powercapping -d failaction -v<bladeid><option>

    The following describes the parameters:

    Parameter

    Parameter Description

    Value

    bladeid

    Server node ID

    1 to 8

    option

    Action performed after node power capping fails

    • 0: no action.
    • 1: shuts down the server node.
    NOTE:

    If the action performed after node power capping fails is set to shutdown, a server node will shut down 10 seconds after its power capping fails.

    Example: # Set the action performed after node power capping fails of server node 1 to "shutdown".

    iBMC:/->ipmcset -t powercapping -d failaction -v 1 1 
    WARNING: The system will power off automatically in 15 seconds after power capping fails. Continue? [Y/N]:y 
    Set blade power capping failed action successfully.     

  8. Run the following command to enable or disable power capping:

    ipmcset -t powercapping -d enable -v <enabled|disabled>

    The following describes the parameters:

    Parameter

    Parameter Description

    Value

    enabled

    Enables power capping.

    -

    disabled

    Disables power capping.

    -

    Example: # Enable chassis power capping.

    iBMC:/->ipmcset -t powercapping -d enable -v enabled  
    Set shelf power capping enable state (enabled) successfully.     

  9. Query and verify the power capping status. For details, see Querying and Configuring Power Capping.
