Replacing a Mainboard of a TaiShan 2280 V2 25-Slot Node

Replacing a Mainboard of a TaiShan 2280 V2 25-Slot Node

This section describes how to replace a mainboard.

Impact on the System

Before replacing a mainboard on a storage node, you must power off the node. This will adversely affect the services running on the node.

Prerequisites

A spare mainboard is ready.

Precautions

Before replacing a mainboard, mark the connections of the cables.

Tools and Materials

  • Flat-head screwdrivers
  • Phillips screwdrivers
  • ESD wrist straps
  • ESD bags
  • Labels

Procedure

  1. Log in to the primary management node as user dsware, and run the sh /opt/dsware/client/bin/dswareTool.sh --op setServerStorageMode -ip Management IP address of the faulty node -mode 1 command to switch to the maintenance mode. To run this command, enter the name and password of CLI super administrator account admin as prompted.
  2. Check whether the BIOS on the spare mainboard needs to be upgraded to a customized BIOS.

    1. Log in to any storage node as user fsadmin.
    2. Run the su - root command and enter the password of user root to switch to user root.
    3. Run the dmidecode -t 4 command. If the command output is as follows, upgrade the BIOS to a customized one after 29 by following the server firmware upgrade guide of the desired version. The customized BIOS is released with FusionStorage Block Storage software.

      Current speed: 2400 MHZ

      Core Enabled: 32

      Version: Kunpeng 920-4826

      If the command output is different from the above, you do not need to upgrade the BIOS.

  3. Remove the faulty node from its cabinet, and remove its chassis cover. For details, see Basic Operations.
