Replacing a Main Control Board Enclosure

Replacing a Main Control Board Enclosure

This section explains how to replace a storage node by replacing main control board enclosure for a Mini-capacity node.

Impact on the System

The Mini-capacity node must be powered off before replacement of a main control board enclosure. Therefore, the services running on the Mini-capacity node will be affected. Perform this operation with caution.

Prerequisites

  • The replacement main control board enclosure is ready.
  • The cable connections have been labeled.

Precaution

  • Only qualified technical support engineers are allowed to replace a main control board enclosure.
  • Ensure that both power supplies of the Mini-capacity node have been shut down.

Tools and Materials

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

Procedure

  1. Wear the ESD wrist strap and ESD gloves. Accomplish the following steps to wear an ESD wrist strap:

    1. Stretch your hand through the ESD wrist strap.
    2. Fasten the buckle and ensure that the ESD wrist strap fully touches the skin.
    3. The ESD wrist strap can be classified into the ESD wrist strap with a plug and the ESD wrist strap with a metal clip.

      • Insert the plug of the ESD wrist strap into the ESD socket of the cabinet.



      • Clip the metal clip of the wrist strap to the square hole on the side of the cabinet.



    4. Ensure that the buckle of the wrist strap is fastened and the plug is inserted tightly into the ESD socket or the metal clip is tightly clipped to the square hole on the cabinet.

  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 Mini-capacity node and power sockets and peripheral devices. Then disconnect the cables.
  4. Pull out the main control board enclosure.

    1. Press the buttons on the inner sides of the two handles on the back of the enclosure, as shown in step 1 in Figure 2-58.
    2. Open the handles completely, as shown in step 2 in Figure 2-58.
    3. The main control board enclosure will be slowly pulled out when you open the handles, as shown in step 3 in Figure 2-58. Pull out the main control board enclosure and place it on an ESD platform.

  5. Remove the system disk modules and NVDIMM module from the main control board enclosure, and put them into ESD bags. For details about how to remove them, see Replacing a System Disk Module and Replacing an NVDIMM Module.
  6. Take the replacement main control board enclosure out of its ESD bag.
  7. Install the system disk modules and NVDIMM module into the main controller board enclosure in sequence. For details about how to install them, see Replacing a System Disk Module and Replacing an NVDIMM Module.
  8. Install the main control board enclosure.

    1. Hold the main control board enclosure and slide it into the cabinet, as shown in step 1 in Figure 2-59.
    2. Lift the two handles on the back of the main control board enclosure upward to push the main control board enclosure into place, as shown in step 2 in Figure 2-59. Close the two handles.

    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. Correctly connect the Mini-capacity node to the power sockets and peripheral devices according to the cable connection labels. Then power on the Mini-capacity node.
  10. 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.
