Use this information to resolve issues that you might have when setting up your system.

Use the information in this section to diagnose and resolve problems that you might encounter during the initial installation and setup of your server.

Solution does not power on​

Complete the following steps until the problem is resolved:
Note
The power-control button will not function until approximately 5 to 10 seconds after the solution has been connected to power.

  1. Make sure that the power-control button is working correctly:

    1. Disconnect the solution power cords.

    2. Reconnect the power cords.

    3. (Trained technician only) Reseat the operator information panel cable, and then repeat steps 1a and 1b.

      • (Trained technician only) If the solution starts, reseat the operator information panel. If the problem remains, replace the operator information panel.

      • If the solution does not start, bypass the power-control button by using the force power-on jumper. If the solution starts, reseat the operator information panel. If the problem remains, replace the operator information panel.

  2. Make sure that the reset button is working correctly:

    1. Disconnect the solution power cords.

    2. Reconnect the power cords.

    3. (Trained technician only) Reseat the operator information panel cable, and then repeat steps 2a and 2b.

      • (Trained technician only) If the solution starts, replace the operator information panel.

      • If the solution does not start, go to step 3.

  3. Make sure that both power supplies installed in the solution are of the same type. Mixing different power supplies in the solution will cause a system error (the system-error LED on the front panel turns on).

  4. Make sure that:

    • The power cords are correctly connected to the solution and to a working electrical outlet.

    • The type of memory that is installed is correct.

    • The DIMMs are fully seated.

    • The LEDs on the power supply do not indicate a problem.

    • The processors are installed in the correct sequence.

  5. Reseat the following components:

    1. Operator information panel connector

    2. Power supplies

  6. Replace the following components. restarting the solution each time:

    1. Operator information panel connector

    2. Power supplies

  7. If you just installed an optional device, remove it, and restart the solution. If the solution now starts, you might have installed more devices than the power supplies support.

  8. See Power supply LEDs.

  9. If the error recurs, check FFDC logs for more details.

    Note
    To collect FFDC logs, you can perform one of the following actions:

    • Insert a USB storage device to the USB connector on SMM2 and then press the USB port service mode button to collect FFDC logs. See System Management Module 2 (SMM2) for the location of the connector and button.

    • Login to the SMM2 WebGUI and click on the Capture button of FFDC in the Management Module section under Enclosure Rear Overview (see Enclosure Rear Overview).

The solution immediately displays the POST Event Viewer when it is turned on​

Complete the following procedure to solve the problem.

  1. Correct any errors that are indicated by the light path diagnostics LEDs.

  2. Make sure that the solution supports all the processors and that the processors match in speed and cache size.

    You can view processor details from system setup.

    To determine if the processor is supported for the solution, see Lenovo ServerProven website.

  3. (Trained technician only) Make sure that processor 1 is seated correctly

  4. (Trained technician only) Remove processor 2 and restart the solution.

  5. Replace the following components one at a time, in the order shown, restarting the solution each time:

    1. (Trained technician only) Processor

    2. (Trained technician only) System board

Embedded hypervisor is not in the boot list​

Complete the following steps until the problem is resolved:

  1. Make sure that the optional embedded hypervisor flash device is selected on the boot manager <F12> Select Boot Device at startup.

  2. Make sure that the embedded hypervisor flash device is seated in the connector correctly.

  3. See the documentation that comes with the optional embedded hypervisor flash device to validate that the device is configured correctly.

  4. Make sure that other software works on the server.

Solution cannot recognize a drive​

Complete the following procedure to solve the problem.

  1. Observe the associated yellow drive status LED. If the LED is lit, it indicates a drive fault.

  2. If the LED is lit, remove the drive from the bay, wait 45 seconds, and reinsert the drive, making sure that the drive assembly connects to the drive backplane.

  3. Observe the associated green drive activity LED and the yellow status LED:

    • If the green activity LED is flashing and the yellow status LED is not lit, the drive is recognized by the controller and is working correctly. Run the diagnostics tests for the hard disk drives. When you start a solution and press the key specified in the on-screen instructions, the Lenovo XClarity Provisioning Manager interface is displayed by default. You can perform hard drive diagnostics from this interface. From the Diagnostic page, click Run Diagnostic > Disk Drive Test.

    • If the green activity LED is flashing and the yellow status LED is flashing slowly, the drive is recognized by the controller and is rebuilding.

    • If neither LED is lit or flashing, check the drive backplane.

    • If the green activity LED is flashing and the yellow status LED is lit, replace the drive. If the activity of the LEDs remains the same, go to step drive problems. If the activity of the LEDs changes, return to step 1.

  4. Make sure that the drive backplane is correctly seated. When it is correctly seated, the drive assemblies correctly connect to the backplane without bowing or causing movement of the backplane.

  5. Reseat the backplane power cable and repeat steps 1 through 3.

  6. Reseat the backplane signal cable and repeat steps 1 through 3.

  7. Suspect the backplane signal cable or the backplane:

    • Replace the affected backplane signal cable.

    • Replace the affected backplane.

  8. Run the diagnostics tests for the SAS/SATA adapter and hard disk drives. When you start a solution and press the key according to the on-screen instructions, the LXPM interface is displayed by default. (For more information, see the “Startup” section in the LXPM documentation compatible with your solution at Lenovo XClarity Provisioning Manager portal page.) You can perform hard drive diagnostics from this interface. From the Diagnostic page, click Run Diagnostic > HDD test/Disk Drive Test.

    Depending on the LXPM version, you may see HDD test or Disk Drive Test.

    Based on those tests:

    • If the adapter passes the test but the drives are not recognized, replace the backplane signal cable and run the tests again.

    • Replace the backplane.

    • If the adapter fails the test, disconnect the backplane signal cable from the adapter and run the tests again.

    • If the adapter fails the test, replace the adapter.

Displayed system memory is less than installed physical memory​

Complete the following procedure to solve the problem.

Note
Each time you install or remove a memory module, you must disconnect the solution from the power source; then, wait 10 seconds before restarting the solution.
  1. Make sure that:

    • No error LEDs are lit on the operator information panel.

    • No memory module error LEDs are lit on the system board.

    • Memory mirrored channel does not account for the discrepancy.

    • The memory modules are seated correctly.

    • You have installed the correct type of memory module.

    • After changing or replacing a memory module, memory configuration is updated accordingly in the Setup Utility.

    • All banks of memory are enabled. The solution might have automatically disabled a memory bank when it detected a problem, or a memory bank might have been manually disabled.

    • There is no memory mismatch when the solution is at the minimum memory configuration.

  2. Reseat the memory modules, and then restart the solution.

  3. Check the POST error log:

    • If a memory module was disabled by a systems-management interrupt (SMI), replace the memory module.

    • If a memory module was disabled by the user or by POST, reseat the memory module; then, run the Setup utility and enable the memory module.

  4. Re-enable all memory modules using the Setup utility, and then restart the solution.

  5. (Trained technician only) Install the failing memory module into a memory module connector for processor 2 (if installed) to verify that the problem is not the processor or the memory module connector.

  6. (Trained technician only) Replace the system board.

A Lenovo optional device that was just installed does not work.​

  1. Check the Lenovo XClarity Controller event log for any events associated with the device.

  2. Make sure that the following conditions are met:

    • The device is installed in the correct port.

    • The device is designed for the solution (see Lenovo ServerProven website).

    • You followed the installation instructions that came with the device, and the device is installed correctly.

    • You have not loosened any other installed devices or cables.

    • You updated the configuration information in the Setup utility. Whenever memory or any other device is changed, you must update the configuration.

  3. Reseat the device that you just installed.

  4. Replace the device that you just installed.

Voltage planar fault is displayed in the event log​

Complete the following procedure to solve the problem.

  1. Revert the system to the minimum configuration. See Enclosure specifications for the minimally required number of processors and DIMMs.

  2. Restart the system.

    • If the system restarts, add each of the items that you removed one at a time, restarting the system each time, until the error occurs. Replace the item for which the error occurs.

    • If the system does not restart, suspect the system board.
