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 interval between removing a disk module and installing the spare part, system performance is compromised. Therefore, replace a disk module during off-peak hours.

Prerequisites

  • A spare part is on hand.
  • 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 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

  • To prevent the disk module from damage, pull out the enclosure of or slide the enclosure into the cabinet slowly.
  • Remove and insert a disk module with even force. Excessive force may damage the appearance or connectors of the disk module.
  • To prevent data loss, replace only a disk module of which status indicator is steady red.
  • The duration of pulling an enclosure completely out of the cabinet must be shorter than five minutes.
  • After sliding an enclosure into a cabinet, wait at least 15 minutes before pulling it out again.
  • Only one enclosure can be pulled out at a time.
  • When the overheating alarm indicator of the high-density disk enclosure is red on, slide the enclosure into the cabinet immediately. Otherwise, system services may be affected.
  • Use SmartKit to replace a failing disk.

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. Loosen the two screws on the panel and pull out the enclosure slowly, as shown in Figure 5-58.

  4. Press the latch of the disk module and pull out the disk module, as shown in Figure 5-59.

    Figure 5-59 Removing a disk module

  5. Put the removed disk module into an ESD bag.
  6. Take the spare part out of its ESD bag.
  7. Open the latch of the spare part, insert the disk module, and close the latch, as shown in Figure 5-60.

  8. Wait approximately two minutes and view the status indicator on the disk module to determine whether the disk module has been successfully installed. Figure 5-61 shows the location of the status indicator on the disk module.

    • If the indicator is steady green, the disk module has been successfully installed.
    • If the indicator is steady red or off, the newly installed disk module is faulty, the slot for the disk module is faulty, or the disk module is incorrectly installed.

  9. After the disk module has been successfully installed, slide the enclosure into the cabinet slowly and fasten the two screws on the panel, as shown in Figure 5-62.

  10. 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.
