Power on and power off problems

Use this information to resolve issues when powering on or powering off the server.

Embedded hypervisor is not in the boot list​

Complete the following steps until the problem is solved.

  1. If the server has been installed, moved, or serviced recently, or if this is the first time the embedded hypervisor is being used, make sure that the device is connected properly and that there is no physical damage to the connectors.

  2. See the documentation that comes with the optional embedded hypervisor flash device for setup and configuration information.

  3. Check Lenovo ServerProven website to validate that the embedded hypervisor device is supported for the server.

  4. Make sure that the embedded hypervisor device is listed in the list of available boot options. From the management controller user interface, click Server Configuration > Boot Options.

    For information about accessing the management controller user interface, see the Opening and Using the XClarity Controller Web Interface section in the XCC documentation version compatible with your server at Lenovo XClarity Controller portal page.

  5. Check Lenovo Data Center Support for any tech tips (service bulletins) related to the embedded hypervisor and the server.

  6. Make sure that other software works on the server to ensure that it is working properly.

Single server does not power on​

Complete the following steps until the problem is resolved:
  1. If you recently installed, moved, or serviced the server, reseat the server in the bay. If the server was not recently installed, moved, or serviced, perform a virtual reseat through the CMM service command. For more information about the CMM service command, see the the "Flex System Chassis Management Module: Command-Line Interface Reference Guide".
  2. Check the event log on the CMM 2 for any events that are related to the server and solve them.
  3. Make sure that the CMM 2 can recognize the server. Log in to the CMM 2 user interface and verify that the server appears in the chassis view. If the CMM 2 cannot recognize the server, remove it, and inspect the server and the back of the node bay to make sure that there is no physical damage to the connectors.
  4. Make sure that the power policy that is implemented on the CMM 2 is sufficient to enable the server node to power on. You can view the power policy using theCMM 2 pmpolicy command or the CMM 2 web interface.
  5. Replace the system-board assembly (see System-board assembly replacement).
    Note
    Until you are able to replace the system-board assembly, you can attempt to power on the server from the CMM 2.

Multiple servers do not power on​

Complete the following steps until the problem is resolved:
  1. If you recently installed, moved, or serviced the computer nodes, reseat the compute nodes in the bays. If the compute nodes were not recently installed, moved, or serviced, perform a virtual reseat through the CMM service command. For more information about the CMM service command, see the the "Flex System Chassis Management Module: Command-Line Interface Reference Guide".
  2. Check the CMM 2 event log for any events that are related to the servers, and solve them.

Server does not power off​

Complete the following steps until the problem is resolved:

  1. Attempt to power off the server through the CMM 2 interface.

  2. Attempt to restart the system-management processor for the compute node through the CMM 2 interface. Click the server in the chassis view and then click Restart System Mgmt Processor. After the system-management processor has been restarted, attempt to power off the node from the CMM 2.

  3. Attempt to power off the server by using the power button on the front of the server.

  4. Attempt to reset the compute node from the CMM 2 command-line interface (CLI) by using the reset command.

  5. Reseat the CMM 2. Then, perform steps 1-4 again.
