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 port module, the system switches services from ports on this module to ports on another module of the peer-end 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 from ports on this module to ports on another module of the local controller or the peer-end 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.
  • During the replacement of a PCIe interface module or SmartIO interface module that is used for controller interconnection, the controller on which the interface module resides becomes offline and all services on the controller are automatically switched to the peer controller. Storage I/Os are suspended for 5 to 10 seconds during the service switchover. The service switch over duration increases if the service load is out of the load bearing limit of a single controller. The replacement may fail due to a heavy service load. In addition, the replacement degrades system performance and reliability. You are advised to perform interface module replacement during off-peak hours. After the replacement is complete, the controller on which the interface module resides will restart and services will be automatically switched back to the controller.
    NOTE:

    Use SmartKit to replace a PCIe interface module or SmartIO interface module that is used for controller interconnection.

Prerequisites

  • The spare part is ready based on the BOM code of the interface module you want to replace and the type of the spare part is the same as that of the interface module you want to replace.
  • A label has been attached to the handle of the spare part.
  • 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

  • The type of the spare part must be same as that of the one you want to replace. Otherwise, parts replacement will fail and the configuration of the interface module will be lost. If the configuration of the interface module is lost, collect logs and contact Huawei technical support.

    For V500R007C30, SmartIO interface modules involve earlier versions and the latest version. The specifications of the SmartIO interface modules vary according to different versions. Therefore, SmartIO interface modules of different versions cannot be used as spare parts for each other. You can identify the versions of the SmartIO interface modules by viewing the labels attached to the handles.

    • Earlier versions: "SmartIO" on the labels attached to the handles.
    • Latest version: "SmartIO+rate" such as "SmartIO+8Gb FC" on the labels attached to the handles.

    For details, see the descriptions about interface modules in the Product Description specific to your product model.

  • 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.
  • 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 VLANs, logical ports, 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 the VLANs, logical ports, and bonded ports on the Ethernet interface module will be restored.
  • 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.
  • If you want to use interface modules of different types, contact Huawei technical support.

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 some items fail in 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 is successfully powered off, as shown in Figure 6-108.

    • If the indicator is off, the interface module is successfully powered off. Proceed to 4.
    • 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.

    NOTE:

    A 2 U controller enclosure is illustrated in the figure. The operation procedure also applies to 3 U and 6 U controller enclosures.

  9. Connect the cables.

    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.

    NOTE:

    It is recommended that the cables be connected four minutes after the module installation to prevent any impact on the status update of the interface module.

  10. Wait approximately two minutes and check the status of the Power indicator on the interface module to determine whether the interface module is successfully installed. Figure 6-111 shows the location of the Power indicator.

    • If the indicator is steady green, the interface module is 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.
