Replacing a 12 x 3.5-Inch Rear Disk Backplane of a TaiShan 5280 V2 36-Slot Node

Replacing a 12 x 3.5-Inch Rear Disk Backplane of a TaiShan 5280 V2 36-Slot Node

A disk backplane provides power and data transmission channels for disks.

Impact on the System

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

Prerequisites

  • A spare disk backplane is ready.

Precautions

None

Tools and Materials

  • Flat-head screwdrivers
  • Phillips screwdrivers
  • ESD gloves
  • 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. Remove the faulty node from its cabinet, and remove its chassis cover. For details, see Basic Operations.
  3. Remove the disk module.

    Correctly record the slots where disk modules reside. Install disk modules into the same slots before and after the replacement. Otherwise, services may be affected.

    1. Press the button that secures the disk module ejector lever, as shown in step 1 in Figure 8-14.

      The ejector lever automatically ejects.

    2. Hold the ejector lever, and pull out the disk module for approximately 3 cm, as shown in step 2 in Figure 8-14.
    3. Wait at least 30 seconds until the disk stops spinning, and slowly pull out the disk module, as shown in step 3 in Figure 8-14.

  4. Remove the air duct.

    Lift the air duct according to the signs on the air duct, as shown in Figure 8-15.

  5. Remove the fan module.

    1. Press the latches on both sides of the fan module to unlock it, as shown in step 1 in Figure 8-16.
      Figure 8-16 Removing a fan module
    2. Lift the fan module slowly, as shown in step 2 in Figure 8-16.
    3. When the fan module is loose, remove it from the slot.

  6. Remove the fan module bracket.

    Press and hold down the latches on both sides of the fan module bracket, and lift the fan module bracket, as shown in steps 1 and 2 in Figure 8-17.

  7. Remove the 12 x 3.5-inch rear disk backplane.

    1. Remove all cables from the rear disk backplane.
    2. Unscrew the rear disk enclosure, as shown in step 1 in Figure 8-18.

  8. Place the removed disk backplane in an ESD bag.
  9. Take the spare disk backplane out of its ESD bag.
  10. Install the 12 x 3.5-inch rear disk backplane.

    1. Hook the disk backplane, and push it in the arrow direction until the latches are locked and it does not move, as shown in Figure 8-21.

    3. Connect the cables for the disk backplane.

  11. Install the fan module bracket.

    Insert the fan module bracket into the chassis, as shown in Figure 8-23.

  14. Install the disk module.

    Install disk modules into the same slots before and after the replacement. Otherwise, services may be affected.

    1. Raise the ejector lever and push the disk module in along the guide rails until it does not move, as shown in step 1 in Figure 8-26.
      Figure 8-26 Installing a disk module
    2. Ensure that the ejector lever is fastened to the beam, and lower the ejector lever to completely insert the disk module into the slot, as shown in step 2 in Figure 8-26.

  15. Install the chassis cover, and put the node back into the cabinet. For details, see Basic Operations.
  16. 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 0 command to switch to the normal mode. To run this command, enter the name and password of CLI super administrator account admin as prompted.
  17. Connect the storage node to the power sockets and peripheral devices according to the cable connection labels. Ensure that all cables are correctly connected and then power on the storage node. If the storage node is not powered on, press the power button on the front panel.
  18. Check whether the backplane is successfully replaced.

    • If the disks are powered on properly and the disk indicators are steady on, the backplane is successfully replaced.
    • If the disk indicators are off, the backplane fails to be replaced. Reinstall it or contact Huawei technical support engineers.

  19. Check the system status.

    On SmartKit, choose Home > Storage > Routine Maintenance > More > Inspection and check the system status.
    • If all inspection items pass the inspection, the inspection is successful.
    • If some inspection items fail, the inspection fails. Rectify the faults by taking recommended actions in the inspection reports. Perform inspection again after fault rectification. If the inspection still fails, contact Huawei technical support.

    For details, see the FusionStorage Block Storage Administrator Guide.
