Impact on the System

The DIMM cannot be used, which affects server performance.

Possible Causes

  • The DIMMs installed are not compatible with the CPU.
  • The DIMM layout does not comply with the configuration rules.


  1. Power off the compute node and remove it from the chassis. Then check the models of the DIMMs for which the alarm is generated.

    You can power off the compute node using either of the following methods:
    • On the HMM CLI, run the smmset -l bladeN -d powerstate -v poweroff command.
    • On the HMM WebUI, choose PSUs & Fans > PSU Management > Power Control, and click the power control button to power off the compute node.

  2. Use the Huawei ServerCompatibility Checker to check whether the DIMM models are compatible with the server.

    • If yes, go to 3.
    • If no, go to 5.

  3. Check whether the DIMMs are installed in correct slots.

    For details about DIMM installation positions, see the user guide of the server you use.

    • If yes, go to 6.
    • If no, go to 4.

  4. Install the DIMMs in correct slots. Then, check whether the alarm is cleared.

    • If yes, no further action is required.
    • If no, go to 6.

  5. Replace the DIMMs with compatible ones and power on the server. Then, check whether the alarm is cleared.

    For details about how to replace a DIMM, see the user guide of the server you use

    • If yes, no further action is required.
    • If no, go to 6.
