Replacing a Disk Module (25-Slot)

Replacing a Disk Module (25-Slot)

This section describes how to replace a disk module, including the replacement of failing disk and faulty disk.

Impact on the System

During the replacement of a disk module, if system reconstruction is complete, host services are not affected; if system reconstruction is not complete, host services are slightly affected.


  • The replacement disk module is ready.
  • To prevent services from being affected, use Huawei-certified disk modules that match the product model as spare disk modules (which are obtained by service engineers based on the part numbers of failed disk modules).
  • The disk module that you want to replace has been located. You can locate disk modules in either of the following ways:
    • Record the enclosure IDs and slot IDs of the disk modules.
    • Use management software to light the enclosure location indicator and disk module location indicator (for details, see the online help of the management software).


  • When handling a disk module, hold only its edge to prevent it from damage.
  • Remove and insert a disk module with even force. Excessive force may damage the appearance or connectors of the disk module.
  • When removing a non SSD disk module, pull the disk module partially out of its slot. Wait about 20 seconds until its disk spins down and then pull it completely out of the slot.
  • To prevent disk module damage, wait at least one minute after removal and before reinserting a disk module, or after insertion and before removal of a disk module.
  • To prevent data loss, replace only a disk module whose Alarm/Location indicator is steady red.
  • Shorten the duration of replacing a disk module as much as possible.
  • Use SmartKit to replace a failing disk (that is not completely faulty yet).
  • Ensure that the replacement disk is inserted in to the same slot as the replaced disk. Otherwise, the system may work incorrectly.

Tools and Materials

  • ESD wrist strap
  • ESD bag
  • Label


  1. Check system status before replacement.
    1. Perform a system status inspection.

      Start SmartKit. On the homepage, choose MyTools > Storage > Parts Replacement > Inspection. The Inspection Wizard step 5-1:Welcome page is displayed after you go to the Inspection page. On the wizard, select Routine inspection and perform the inspection as instructed by the wizard.

      For details, you can click .


      If some items fail the inspection, rectify the faults by performing the recommended actions in the inspection reports. Ensure that all other parts except the parts to be replaced are working correctly.

    2. Perform a pre-replacement inspection.

      On the homepage, choose MyTools > Storage > Parts Replacement > FRU Replacement. On the FRU Replacement page, select the part that you want to replace and perform the pre-replacement inspection as prompted. For details, see Using SmartKit for Parts Replacement (Recommended).

      You can proceed to next step only when all items pass the pre-replacement check and the replacement page is displayed. If any item fails, rectify the fault by taking recommended actions in the inspection reports.

  2. Wear an ESD wrist strap.
  3. Press the latch on the disk module to release the handle and pull out the disk module, as shown in Figure 5-12.

  4. Put the removed disk module into an ESD bag.
  5. Take the replacement disk module out of its ESD bag.
  6. Open the handle of the replacement disk module, insert the disk module into the empty slot, and close the handle, as shown in Figure 5-13.

  7. Wait about two minutes and check the status of the Running and Alarm/Location indicators on the disk module to determine whether the disk module is successfully installed. Figure 5-14 shows the locations of the Running and Alarm/Location indicators.

    • If the Running indicator is steady on and the Alarm/Location indicator is off, the disk module is successfully installed.
    • If the Running indicator is off or the Alarm/Location indicator is steady on, the newly installed disk module is faulty, the disk module slot is faulty, or the disk module is incorrectly installed.

  8. Confirm the replacement.
    1. Perform a post-replacement inspection.

      After the replacement, on the SmartKit page, click Replaced. Perform the post-replacement inspection as prompted.

    2. Check the system status after the replacement.

      Check the system status again on the Inspection page after the replacement. If any inspection item fails, rectify the fault based on the suggestions.

    3. Check services on a host for any storage-related error.

Follow-up Procedure

After the disk module is replaced, label it to facilitate subsequent operations.
