Replacing a 4 x 2.5-Inch Rear Disk Assembly

Replacing a 4 x 2.5-Inch Rear Disk Assembly

NOTE:

This chapter applies to TaiShan 2280 V2 12-slot nodes, TaiShan 2280 V2 25-slot nodes, TaiShan 5280 V2 36-slot nodes, 2288H V5 12-slot nodes, and 5288 V5 36-slot nodes.

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

Impact on the System

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

Prerequisites

A spare disk assembly 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 7-1.

      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 7-1.
    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 7-1.

  4. Remove the 4 x 2.5-inch rear disk assembly.

    1. Remove all cables from the rear disk assembly.
    2. Unscrew the rear disk assembly, as shown in step 1 in the following figures.

      Figure 7-4 Removing the rear disk assembly of a TaiShan 2280 V2 node
      Figure 7-5 Removing the rear disk assembly of a TaiShan 5280 V2 node
    3. Take out the rear disk assembly, as shown in step 2 in the preceding figures.

  5. Place the removed disk assembly in an ESD bag.
  6. Take the spare disk assembly out of its ESD bag.
  7. Install the 4 x 2.5-inch rear disk assembly.

    1. Install the rear disk assembly in the chassis and tighten the screws, as shown in steps 1 and 2 in the following figures.

      Figure 7-9 Installing the rear disk assembly of a TaiShan 5280 V2 node
    2. Connect the cables for the rear disk assembly.

  8. 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 7-10.
      Figure 7-10 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 7-10.

  9. Install the chassis cover, and put the node back into the cabinet. For details, see Basic Operations.
  10. 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.
  11. 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.
  12. Check whether the disk assembly is successfully replaced.

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

  13. 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.

Follow-up Procedure

Label the replaced disk assembly to facilitate subsequent operations.
