Replacing a NIC

Replacing a NIC

This section describes how to replace a GE network interface card (NIC) that provides two GE ports.

Impact on the System

Before replacing a NIC, you must power off the P36E or C36E node. This will adversely affect the services running on the node. Exercise caution when performing this operation.

Prerequisites

  • The replacement NIC is ready.
  • You have opened the cover to take out the NIC that resides in the storage node.

Precaution

  • Only professional technical support engineers are allowed to replace a NIC.
  • A P36E or C36E node has two power modules. Ensure that both are disconnected.

Tools and Materials

  • Flat-head screwdrivers
  • Phillips 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 cabinet.
    1. Loosen the captive screws on the panel using a Phillips screwdriver, as shown in step 1 in Figure 3-225.

    2. Slowly pull the storage node out along the guide rails, as shown in step 2 in Figure 3-225.
    3. Press the release buttons on both sides and pull the storage node out of the cabinet along the guide rails, as shown in step 3 in Figure 3-225.
  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 3-226.
    2. Open the ejector lever to push the enclosure cover backward, as shown in step 2 in Figure 3-226.

  6. Remove the system disk module. For details, see 7 in Replacing a System Disk Backplane.
  7. Remove a NIC.
    1. Use a Phillips screwdriver to unscrew the NIC, as shown in step 1 in Figure 3-227.

    2. Slowly pull out the NIC to have the NIC disconnected from the port on the mainboard. Then slowly lift the NIC out of the node, as shown in step 2 in Figure 3-227.
  8. Put the removed NIC into an ESD bag.
  9. Take the replacement NIC out of its ESD bag.
  10. Install the NIC.
    1. Put the NIC down in the enclosure and horizontally push it into the enclosure to have the NIC connected to the port on the mainboard, as shown in step 1 in Figure 3-228.

    2. Use a Phillips screwdriver to loosen two screws on the NIC, as shown in step 2 in Figure 3-228.
  11. Install the system disk module. For details, see 14 in Replacing a System Disk Backplane.
  12. 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 3-229.

    2. Tighten the latch to secure the ejector lever of the enclosure cover using flat-head screwdriver, as shown in step 3 in Figure 3-229.
  13. Put the storage node into the cabinet.
    1. Arrange at least four persons to lift the storage node on both sides, align the inner rails on the storage node with the holding rails, and push the storage node into the cabinet along the holding rails, as shown in Figure 3-230.

    2. Press the release buttons on both sides, and push the storage node into the cabinet until the storage node cannot move forward, as shown in Figure 3-231.

    3. Tighten the two captive screws on the mounting ears to secure the storage node, as shown in Figure 3-232.

  14. Connect the storage node to the power sockets and peripheral devices according to the cable connection labels. Then power on the storage node.
  15. 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:
    ********************************************************************************
    

  16. Check whether the network ports on the storage node are named NIC1.
    1. On the KVM, run ifconfig -a to check whether the network ports on the storage node are named NIC1.

      • 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.
  17. 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

  18. Inspect the system using SmartKit. Choose Home > Storage > Routine Maintenance > More > Inspection to check the system status. For details, see the OceanStor 9000 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 NIC, label the replaced NIC to facilitate subsequent operations.
