Replacing an Interface Module

Replacing an Interface Module

This section describes how to replace an interface module.

Impact on the System

  • During the replacement of a front-end interface module, the system switches services from ports on this module to ports on another module of the local controller or the peer controller. If available links are unable to bear the current service load, host latency increases and the system performance degrades. If there are no other redundant links, services run on a single link and the system reliability degrades.
  • During the replacement of a back-end port module, the system switches services to the peer controller. A back-end port has no other redundant links, and disks in the loop all run with a single path, causing the system reliability to degrade.

Prerequisites

  • The new interface module is of the same type as the one to be replaced. If you want to use a different type of interface module, you must contact Huawei technical support.
  • A spare part is on hand.
  • The interface 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.
  • Services running on the interface module that you want to replace have been stopped.
  • The cable connection positions of the interface module that you want to replace are labeled on the cables.

Precautions

  • Note the following if you want to replace a SmartIO interface module:
    • For the new SmartIO interface module without an optical module

      Remove the optical module from the SmartIO interface module you want to replace and insert the new SmartIO interface module into the controller enclosure. After the Power indicator of the new interface module is steady green, wait at least one minute and insert the removed optical module into the new SmartIO interface module.

    • For the new SmartIO interface module with an optical module

      Insert the new SmartIO interface module into the controller enclosure. If you want to use the optical module on the replaced interface module, wait at least one minute after the Power indicator of the new SmartIO interface module is steady green, and then insert the optical module into the new SmartIO interface module.

  • Remove and insert an interface module with even force. Excessive force may damage the appearance or connectors of the interface module.
  • An interface module must be replaced within five minutes. Otherwise, the system heat dissipation is compromised.
  • After removing an interface module, wait at least fifteen seconds before inserting one. Otherwise, the system cannot identify the status change of the interface module.
  • In the case of a SmartIO interface module, if you replace an interface module that uses Ethernet protocol with one that uses Fibre Channel protocol, the Ethernet port configuration information will be deleted, and bonded ports on the original interface module will become unavailable. If you replace the interface module again with one that uses Ethernet protocol, the Ethernet port configuration information will not be restored, but bonded ports on the Ethernet interface module will.
  • In the case of a SmartIO interface module, if you replace an interface module that uses Fibre Channel protocol with one that uses Ethernet protocol, the Fibre Channel port configuration information will be deleted. If you replace the interface module again with one that uses Fibre Channel protocol, the Fibre Channel port configuration information will not be restored.

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 > Parts Replacement. On the Parts Replacement page, click FRU Replacement. Then complete the check before the replacement as prompted. For details, see Replacing an FRU.

    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. Check the status of the Power indicator/Hot Swap button on the interface module to determine whether the interface module has been successfully powered off, as shown in Figure 6-20.

    • If the indicator is off, the interface module has been successfully powered off, skip to Step 5.
    • If the indicator is on, use a paper clip or a similar object to press the Power indicator/Hot swap button on the interface module to power off the interface module.

  4. Remove the cables from the interface module that you want to replace.
  5. Press the latch on the interface module to release the handle and pull out the interface module, as shown in Figure 6-21.

    Figure 6-21 Removing an interface module

  6. Put the removed interface module into an ESD bag.
  7. Take the spare part out of its ESD bag.
  8. Insert the spare part into the empty slot until it clicks into place, as shown in Figure 6-22.

  9. Connect the cables.

    After the interface module is installed, you are advised to wait four minutes before connecting the cables so that the status of the new interface module can be updated.

    The cable connection positions of the new interface module must be identical to those of the original interface module. Otherwise, service operation will be affected.

  10. Wait about two minutes and check the status of the Power indicator on the interface module to determine whether the interface module has been successfully installed. Figure 6-23 shows the location of the Power indicator.

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

  11. 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.

      On the Parts Replacement page, click Inspection to check the system status again. If any item fails inspection, 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 interface module is replaced, label it to facilitate subsequent operations.
