Replacing a PCIe Card

Replacing a PCIe Card

You can configure a GE/10 GE/25 GE or IB Peripheral Component Interconnect Express (PCIe) card that provides 2 x GE, 2 x 10 GE optical ports, 2 x 25 GE optical ports, or 2 x InfiniBand ports.

Impact on the System

Before replacing a PCIe card, you must power off the storage node. This will adversely affect the services running on the node.

Prerequisites

  • The replacement PCIe card is ready.
  • You have opened the cover to take out the PCIe card that resides in the storage node.
  • You have obtained the OceanStor 9000 V5 Version Mapping and OceanStor 9000 V5 Node Firmware Upgrade Guide of the corresponding version.
    NOTE:
    You can log in to http://support.huawei.com/enterprise/, choose Support > Cloud Storage, and click the product model to go to the document page of the product. Then, click Downloads tab page. On the Downloads tab page, click the version that you need download, the download page is displayed. And then download the documents.

Precaution

  • Only professional technical support engineers are allowed to replace a PICe card.
  • A storage node has two power modules. Ensure that both are disconnected.
  • If the PCIe card is an IB card or RoCE card, the system automatically checks the firmware version of the new PCIe card after the replacement. If the firmware version does not match the OFED version installed on the device, the system automatically upgrades the firmware of the PCIe card. After the upgrade is complete, the device will restart.

Tools and Materials

  • Flat-head screwdrivers
  • Electrostatic discharge (ESD) gloves
  • ESD wrist straps
  • ESD bags
  • Labels

Procedure

  1. Wear an ESD wrist strap or ESD gloves.
  2. Use the KVM to log in to the operating system of the node, enter user name root and its password (default: Root@storage), and run poweroff command to power off the node.

    Wait until the KVM has no output. The power-off is complete.

  3. Remove all power cables and external signal cables.
  4. Remove the storage node from the enclosure.
    1. Slide the storage node out of the cabinet, as shown in step 1 in Figure 2-188.
    2. Press the baffle plate and slide the storage node out of enclosure, as shown in step 2 in Figure 2-188.

  5. Remove the enclosure cover.
    1. Use a flat-head screwdriver to loosen the latch that secures the ejector lever of the enclosure cover, as shown in step 1 in Figure 2-189.
    2. Open the ejector lever to push the enclosure cover backwards, as shown in step 2 in Figure 2-189.

  6. Remove the PCIe card.
      1. Open the latch on the PCIe card, as shown in Figure 2-190.

        Figure 2-190  Removing a PCIe card

      2. Slowly pull out the PCIe card upwards, as shown in step 2 in Figure 2-190.
    1. Put the removed PCIe card into an ESD bag.
    2. Take the replacement PCIe card out of its ESD bag.
    3. Install the PCIe card.
      1. Insert the PCIe card into the expansion slot (note that the interface model must match), as shown in step 1 in Figure 2-191.

      2. Close the latch on the PCIe card, as shown in step 2 in Figure 2-191.
    4. Install the enclosure cover.
      1. Place the enclosure cover horizontally, align it with the fixing slots on both side panels of the enclosure, and close the ejector lever, as shown in steps 1 and 2 in Figure 2-192.
      2. Use a flat-head screwdriver to tighten the latch in order to secure the ejector lever of the enclosure cover, as shown in step 3 in Figure 2-192.

    5. Put the storage node into the cabinet.
      1. Align the securing holes in the inner rails with the positioning pins on the storage node, and secure the inner rails to the storage node, as shown in step 1 in Figure 2-193.
      2. Align the inner rails with the holding rails, and push the storage node into the holding rails, as shown in step 2 in Figure 2-193.
      3. Ensure that the storage node is horizontally installed and screwed.

    6. Connect the storage node to the power sockets and peripheral devices according to the cable connection labels. Then power on the storage node.
    7. Log in to the storage node using the KVM.
    8. Clear NVDIMM data.
      1. Press Delete repeatedly when the screen shown in the following figure is displayed during server startup.

        Figure 2-194  BIOS startup screen

      2. Enter a BIOS password as prompted. The screen for setting the BIOS is displayed.

        NOTE:

        The default BIOS password is Huawei12#$ for the French or American keyboard and is Huawei12£$ for the English keyboard.

        To ensure system security, you are advised to change the default BIOS password after the first login.

      3. Choose Security > Clear NvDimm Flash.

        Figure 2-195  Choosing Clear NvDimm Flash

      4. In the Clear NvDimm Flash? dialog box, select Yes and press Enter.

        Figure 2-196  Starting to clear NVDIMM data

      5. Wait 20 seconds. Check whether the displayed dialog box states "Clear NvDimm flash success. Please reboot system!"

        • If yes, go to 14.f.
        • If no, contact technical support.

    9. Execute the following script to check the storage node status.

      cd /opt/product/deploy/script

      ./envcheck.py

      The normal self-check result is as follows:

      [2014-11-05 16:45:02,491][INFO    ][module:envcheck, line:0620] 
      ********************************************************************************
      Check Item: SNAS Environment Check Summary
      Check Pass:True
      Check Cmd :
      Check Info:
      kernel version: OK
      nvdimm driver: OK
      TOE driver: OK
      HardRaid status: OK
      Firewall status: OK
      Command Output:

    10. Check whether the network ports on the storage node are named SLOT4-0, SLOT4-1, SLOT5-0, and SLOT5-1.

      NOTE:
      In 100 Gbit/s IB networking, the network ports of storage nodes are named SLOT4-0, SLOT4-1, SLOT7-0, and SLOT7-1.

      1. On the KVM, run ifconfig -a to check whether the network ports on the storage node are named SLOT4-0, SLOT4-1, SLOT5-0, and SLOT5-1.

        • If yes, the PCIe card is successfully replaced
        • If no, go to 16.b.

      2. Run reboot to restart the storage node, so that new PCIe cards can be identified.
    11. On DeviceManager, check the status of the storage node.
      1. Start the browser on the maintenance terminal and log in to DeviceManager.
      2. In the Alarms area on the home page, check whether a new alarm is reported.

        • If yes, clear the alarm according to the alarm help.
        • If no, go to 17.c.

      3. On the right of the home page, click System to go to the System page.
      4. Click Device View tab to go to the Device View page.
      5. In Nodes, check the status of the node that is newly added to the cluster.

        • Health Status: Normal
        • Running Status: Online

    12. Inspect the system using SmartKit. Choose Home > Storage > Routine Maintenance > More > Inspection to check the system status. For details, see the OceanStor 9000 V5 Routine Maintenance.

      • If all inspection items are successful: The inspection is successful.
      • If some inspection items fail the inspection: The inspection is failed. Rectify the faults by taking recommended actions in the inspection reports. You need to reperform inspection after rectifying. If the inspection is still failed, contact Huawei technical support.

    Follow-up Procedure

    After replacing the PCIe card, label the replaced PCIe card to facilitate subsequent operations.
