Replacing a Storage Node

Replacing a Storage Node

This section explains how to replace a storage node.

Impact on the System

You must power off a storage node before replacing it. Exercise caution when performing this operation.

Prerequisites

  • The replacement storage node is ready.
  • The storage node that you want to replace has been located.
  • The cable connection positions of the storage node that you want to replace have been labeled on the cables.

Precaution

  • Remove and insert a storage node with even force. Excessive force may damage the appearance or connectors of the storage node.
  • To prevent personal injury, arrange two persons to replace it.

Tools and Materials

  • Phillips screwdriver
  • ESD wrist strap
  • ESD bag
  • ESD table
  • Labels

Procedure

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

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

  3. Label the cable connections between the node and power sockets and peripheral devices. Disconnect the cables from the faulty storage node.
  4. Remove the storage node from the rack.
    1. Use a Phillips screwdriver to remove the M6 screws from the mounting ears, as shown in step 1 in Figure 6-83.
    2. Pull the storage node out of the cabinet along guide rails and place the storage node on an ESD table, as shown in step 2 in Figure 6-83.

  5. Take out the replacement storage node and place it on an ESD table.
  6. Remove all system disk modules, service disk modules, and non-volatile dual in-line memory modules (NVDIMMs) from the faulty storage node and reinstall them in the replacement storage node.
    1. Remove all system disk modules, service disk modules, and NVDIMMs from the replacement storage node and put them into ESD bags.
    2. Correctly label the slot IDs of all system disk modules and service disk modules in the faulty storage node.
    3. Remove all system disk modules and service disk modules from the faulty storage node and insert them into the replacement storage node in original sequence.

      Insert the system disk modules and service disk modules into the same slots in the replacement storage node as in the faulty storage node. Otherwise, system services may be affected.

    4. Remove the NVDIMMs from the faulty storage node and insert them into the replacement storage node.
  7. Mount the replacement storage node.
    1. Slide the storage node into the cabinet along guide rails, as shown in step 1 in Figure 6-84.
    2. Use M6 screws to secure the storage node in the cabinet, as shown in step 2 in Figure 6-84.
    3. Ensure that the storage node is horizontally installed and tightly screwed.

  8. Connect the end marked with PC of the KVM cable to the VGA port of the storage node.

    After hardware installation, if there are operations need to be performed using BIOS, for the initial startup, clear NVDIMM data using the BIOS. Otherwise, the operating system may fail to be started. Before connecting the power cable and powering on the storage node, connect the KVM cable, and then adjust the display content of the KVM to the port connected to the storage node.

  9. Connect the power cable to the storage node according to the cable connection label.
  10. Log in to the storage node using the KVM.
  11. Clear NVDIMM data.
    1. During the system startup process, press Esc when the Press Esc for boot options message is displayed, choose SCU, input the BIOS password to enter the BIOS screen.

    2. Choose Security > Clear NvDimm Flash.

      Figure 6-87  Choosing Clear NvDimm Flash

    3. In the Clear NvDimm Flash? dialog box, select Yes and press Enter.

    4. Wait 20 seconds. Check whether the displayed dialog box states "Clear NvDimm flash success. Please reboot system!"

      • If yes, go to 11.e.
      • If no, contact technical support.

  12. Activate the RAID (system disks) of the storage node.
    1. Press Ctrl+C to go to the SAS BIOS interface when the following information is displayed during the startup of the operating system running on the storage node.

      Press Ctrl-C to start LSI Corp Configuration Utility...

    2. Press Enter and choose RAID Properties > View Existing Volume > Manage Volume > Activate Volume, as shown in Figure 6-91.

    5. Press Esc, choose Save changes then exit this menu, press Esc twice, then chooseExit the Configuration Utility and Reboot.
  13. Configure an IP address for the Intelligent Platform Management Interface (IPMI) of the storage node.
    1. Run the restart command on the KVM to restart the storage node.
    2. During the system startup process, press Esc when the Press Esc for boot options message is displayed, choose SCU, input the BIOS password to enter the BIOS screen.
    3. Choose Advanced > IPMI BMC Configuration > BMC Configuration.
    4. Set IP Source to Static.
    5. Set correct IPv4 IP Address, IPv4 Subnet Mask, and IPv4 Gateway Address.
    6. Press F10 and select yes to save the configurations and exit the BIOS screen.
  14. Run poweroff to power off the storage node.
  15. Press the Power button on the front panel of the storage node to power on the storage node.
  16. Run the script to check the status of the storage node.

    cd /opt/product/deploy/script

    ./envcheck.py

    Normal result is as follows:
    [2014-11-05 16:45:02,491][INFO    ][module:envcheck, line:0620]

  17. Check whether the network ports of the storage node are named A0-0, A0-1, B3-0, and B3-1.
    1. Run ifconfig -a on the KVM to check whether the network ports of the storage node are named A0-0, A0-1, B3-0, and B3-1.

      • If yes, go to 18.
      • If no, go to 17.b.

    2. Run reboot to restart the storage node to identify the new network adapter.
  18. Connect signal cables to the storage node according to the cable connection label.
  19. Check the status of the storage node on the DeviceManager.
    1. Start the browser on the maintenance terminal and log in to the DeviceManager.
    2. In the Alarms area on the home page, check whether a new alarm is reported.

      • If yes, handle the alarm according to the alarm help.
      • If no, go to 19.c.

    3. On the right of the home page, click System to go to the System page.
    4. Click Device View tab to go to the Device View page.
    5. In Nodes, check the status of the node that is newly added to the cluster.

      • Health Status: Normal
      • Running Status: Online

  20. Inspect the system using SmartKit. Choose Home > Storage > Routine Maintenance > More > Inspection to check the system status. For details, see the OceanStor 9000 V5 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.
