Replacing a Storage Node

Replacing a Storage Node

This section explains how to replace a storage node.

Impact on the System

Power off the storage node that you want to replace and replace it with caution.

Prerequisites

  • A new storage node has been prepared. The model of the new storage node must be the same as that of the storage node to be replaced.
  • The storage node that you want to replace has been located.
  • The cable connection on the new storage node is clearly marked.

Precaution

  • Use even strength when you remove or insert a storage node. 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 straps
  • ESD bags
  • 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 cables of the faulty storage node.
  4. Remove the faulty node from the cabinet.
    1. Use a Phillips screwdriver to remove M6 screws from the faulty storage node, as shown in step 1 in Figure 3-71.
    2. Pull the faulty storage node out of the cabinet along guide rails and place the storage node on the ESD table, as shown in step 2 in Figure 3-71.

    Figure 3-71  Removing a faulty storage node

  5. Put the new storage node on the ESD table.
  6. Install all the system disk modules, service disk modules, and NVDIMM memory modules of the faulty storage node to the new storage node.
    1. Remove all the system disk modules, service disk modules, and NVDIMM memory modules from the faulty storage node and place them in 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 NVDIMM memory modules of the faulty storage node and insert them to the new storage node.
  7. Install the new storage node into the cabinet.
    1. Slide the storage node into the cabinet along guide rails, as shown in step 1 in Figure 3-72.
    2. Use M6 screws to fix the storage node in the cabinet, as shown in step 2 in Figure 3-72.
    3. Ensure that the storage node is horizontally installed and tightly screwed.

  8. Insert the KVM cable's end labeled PC 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 power cables to the power socket of the new storage node based on cable labels.
  10. Log in to the new storage node using the KVM.
  11. Clear NVDIMM data.
    1. During the system startup process, hold down F2 or 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 3-73  Choosing Clear NvDimm Flash

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

      Figure 3-74  Starting to clear NVDIMM data

    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 system disk RAID group of the storage node.
    1. If the following information is displayed during the startup of the operating system of the storage node, press Ctrl+C to go to the SAS BIOS interface.

      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 3-77.

    5. Press Esc, choose Save changes then exit this menu, press Esc twice, then choose Exit the Configuration Utility and Reboot.
  13. Configure an IP address for an IPMI Port of the storage node.
    1. On the KVM, run the restart command to restart the storage node.
    2. During the system startup process, hold down F2 or press Esc when the Press Esc for boot options message is displayed, choose SCU, input the BIOS password to enter the BIOS screen.
    3. Navigate to Advanced > IPMI BMC Configuration > BMC Configuration.
    4. Set IP Source to Static.
    5. Set a correct IPv4 IP Address, IPv4 Subnet Mask, and IPv4 Gateway Address.
    6. Press F10 and select yes to save configurations and exit the BIOS screen.
  14. Restart the storage node and go to the lower kernel version to check the status of the storage node.
    1. Restart the storage node and go to the lower kernel version, as shown in Figure 3-80.

    2. Run the script to check the status of the storage node.

      cd /opt/huawei/deploy/script

      ./envcheck.py

      Normal result is as follows:
      [2014-12-16 17:46:41,769][INFO    ][module:envcheck, line:0654]
