Replacing a Disk Module

Replacing a Disk Module

This section describes how to replace a disk module, including the replacement of failing disks (disks not yet completely faulty) and faulty disks.

Impact on the System

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

Prerequisites

  • A spare part is on hand.
  • Huawei-certified disk modules that match the product model are used as spare disk modules. These modules are obtained by service engineers based on the part codes of failed disk modules.
  • The disk module that you want to replace has been located.
NOTE:

You can locate a component in either of the following ways:

  • Log in to DeviceManager and go to the System page. On the System page, check the device view and locate the position of the component to be replaced. If the component has a Location indicator, turn on the indicator. (For details about how to turn on a Location indicator, see the online help of DeviceManager.)
  • Use the Alarm indicator of the component to locate its position.

Precautions

  • 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 it partially out of its slot. Wait about 20 seconds until it spins down and then pull it completely out of the slot.
  • After inserting or removing a disk module, wait at least one minute before removing or inserting it to prevent disk module damage.
  • To prevent data loss, replace only a disk module of which Alarm/Location indicator is steady red.
  • Complete the replacement within five minutes after removing the original disk. Otherwise, the system heat dissipation is compromised.
  • Use SmartKit to replace a failing disk.
  • Ensure that the spare part 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
  • Labels

Procedure

  1. Check status before replacement.

    1. Check system status.

      Start SmartKit and choose Home > Storage > Routine Maintenance > Health Check. On the Health Check page, perform inspection as instructed. For details, see Checking System Status.

      NOTE:

      If any 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 properly.

    2. Check the status of the parts to be replaced.

      Start SmartKit and choose Home > Storage > Parts Replacement > More > Parts Replacement (CRU). On the CRU replacement page, complete the check before the replacement as prompted. For details, see Replacing a CRU.

    You can proceed to next steps only when all items pass the pre-replacement check and the replacement page is displayed. If any item fails, rectify the fault as prompted.

  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 5-41.

    Figure 5-41 Removing a disk module

  4. Put the removed disk module into an ESD bag.
  5. Take the spare part out of its ESD bag.
  6. Open the handle of the spare part, insert the spare part into the empty slot, and close the handle, as shown in Figure 5-42.

  7. Wait approximately two minutes and check the status of the Running and Alarm/Location indicators on the disk module to determine whether the disk module has been successfully installed. Figure 5-43 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 has been 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 parts replacement, return to the SmartKit page and click Replaced. Then complete the parts check after the replacement as prompted.

    2. Check system status.

      Choose Home > Storage > Routine Maintenance > Health Check to check the system status again. If any inspection item fails, rectify the fault based on the suggestions in the inspection report.

    3. After the preceding procedure is complete, check services on the host for storage-related errors.

Follow-up Procedure

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