Replacing a Controller Module

Replacing a Controller Module

This section explains how to replace a controller module of the C72.

Impact on the System

You must power off the C72 before replacing a controller module. This interrupts the services running on the C72. Exercise caution when performing this operation.

Prerequisites

  • A replacement controller module is ready.
  • The controller module that you want to replace has been located.
  • The cable connection positions of the controller module that you want to replace are labeled on the cables.
  • The cables have been disconnected from the controller module that you want to replace.
  • You have obtained the EulerLinux.x86_64.iso file by decompressing the OceanStor_9000_version-os.zip package and a USB flash drive with a usable capacity of at least 1 GB.
    NOTE:
    How to obtain the operating system image refer to OceanStor 9000 Software Installation Guide.

Precaution

  • After the controller is replaced, the SPH hot patch on the original controller is lost. Therefore, you must install the SPH hot patch on the new controller.
  • Use care when you remove and insert a controller module to avoid any damage to the appearance or connectors of the controller module.
  • You are advised to replace a controller module within the shortest time possible.

Tools and Materials

  • ESD wrist strap
  • ESD bag
  • Labels
  • USB flash drive

Procedure

  1. Wear an ESD wrist strap.
  2. Log in to the node through the serial port as user root (default password is Root@storage), then run poweroff to poweroff the node and wait for the shutdown to complete.

    Set Bits per second to 115200, Data bits to 8, Stop bits to 1, Parity to None, and Flow control to None.

    Wait for the serial screen to have no output, indicates that the shutdown has been completed.

  3. After marking the cable connection positions on the new control module, unplug cables from the control module to be replaced.
  4. Press the latch on the controller module, open the ejector handle, and remove the controller module, as shown in Figure 7-20.

  5. Use a Phillips screwdriver to remove the screw from the interface module, and pull out the interface module upwards, as shown in Figure 7-21.

    Figure 7-21  Removing an interface module

  6. Place the removed controller module into an ESD bag.
  7. Take the replacement controller module out of its ESD bag.
  8. Insert the interface module downwards into the slot, and use the Phillips screwdriver to fasten the interface module to the replacement controller module, as shown in Figure 7-22.

  9. Open the ejector handle of the replacement controller module, insert the controller module into the empty slot, and close the ejector handle, as shown in Figure 7-23.

  10. Connect cables.
  11. Wait about 2 minutes and check the statuses of the power and alarm indicators on the controller module to determine whether the controller module is successfully installed. Figure 7-24 shows the locations of the power and alarm indicators on a controller module.

    • If the power indicator is on and the alarm indicator is off, the controller module is successfully installed.
    • If the power indicator is off or the alarm indicator is on, the newly installed controller module is faulty, the slot that houses the controller module is faulty, or the controller module is incorrectly installed.

  12. Use an operating system image file matching the original version of the node to be restored. You can refer to OceanStor 9000 Software Installation Guide to install an operating system image.

    If you want to obtain the version information about the node, log in to the DeviceManager, click the device icon to go to Device View. Then click the node name and choose Basic Node Information.

  13. Log in to the operating system as user root by using the serial port. Configure a preset IP address for an original back-end network port of the node, enabling the node to communicate with other nodes in the system. For example, if the back-end network port is P0, its preset IP address is 192.168.0.10, and subnet mask is 16 bits, run the ifconfig P0 192.168.0.10/16 command to configure the IP address.

    The back-end network port name and IP address of a node can be found in the configuration file for software installation. Or you can log in to the DeviceManager, click the device icon to go to Device View. Then click the node name and choose Ports.

  14. On the node to be repaired, run the /usr/bin/BackUp_KeyData_Recovery.sh local_ip remote_ip command to restart the node.

    In the command, local_ip is the back-end network IP address of the node to be restored, and remote_ip s that of the normal node. The versions of the two nodes must be the same. If you want to obtain the version information about the nodes, log in to the DeviceManager, click the device icon to go to Device View. Then click the node name and choose Basic Node Information.

  15. Log in to the DeviceManager, click the device icon to go to Device View. Then click the node name and choose Basic Node Information. View whether the node is operating correctly.

    If a node is normal, its Health Status is Normal and Running Status is Online.

    • If yes, go to 16.
    • If no, contact technical support engineers.

  16. Inspect the system using SmartKit. Choose Home > Storage > Routine Maintenance > More > Inspection to check the system status. For details, see the OceanStor 9000 Routine Maintenance.

    • If all inspection items are successful: The inspection is successful.
    • If some inspection items fail the inspection: The inspection is failed. Rectify the faults by taking recommended actions in the inspection reports. You need to reperform inspection after rectifying. If the inspection is still failed, contact Huawei technical support.

  17. Check the firmware version.
    1. Use a serial port to log in to the operating system as user root.
    2. Run the command cli_start -u admin to log in to the CLI. Enter the password of user admin when prompted.
    3. Run show node firmware_c72 to check whether the value of Matched is yes.

      • If yes, no action is required.
      • If no, run reboot. The firmware version will be upgraded automatically.

Follow-up Procedure

After replacing the controller module, label it to facilitate subsequent operations.
