About this task

Options for changing the Ethernet link configuration of the E5700SG controller include:

Before changing the link configuration, you must place the E5700SG controller controller into maintenance mode. Putting a StorageGRID appliance into maintenance mode might make the appliance unavailable for remote access.


  1. Follow these steps to place the E5700SG controller into maintenance mode.
    1. From the Grid Manager, select Nodes.
    2. Select the appliance Storage Node.
    3. Select the Tasks tab.

      Maintenance Mode button for appliance
    4. Click Maintenance Mode.
      A confirmation dialog appears.

    5. Enter the provisioning passphrase, and click OK.
      A confirmation message lists the URLs you can use to access the StorageGRID Appliance Installer while the controller is in maintenance mode.

    6. Wait a few minutes for the controller to reboot into maintenance mode. Then, browse to any of the URLs displayed.
      Note: If possible, use the URL containing the IP address of the appliance's Admin Network port.
      Note: Accessing requires a direct connection to the local management port.
    7. Confirm that the appliance is in maintenance mode by noting the maintenance mode message on the StorageGRID Appliance Installer home page.

  3. Make the desired changes to the link configuration.
    For more information on the options, see "Configuring network links."
  4. When you are satisfied with your selections, click Save.
    Note: You might lose your connection if you made changes to the network or link you are connected through. If you are not reconnected within 1 minute, re-enter the URL for the StorageGRID Appliance Installer using one of the other IP addresses assigned to the appliance: https://E5700SG_Controller_IP:8443
  5. From the StorageGRID Appliance Installer, select Configure Networking > Ping Test.
  6. Use the Ping Test tool to check connectivity to IP addresses on any networks that might have been affected by the link configuration changes you made in step 3.
    In addition to any other tests you choose to perform, confirm that you can ping the grid IP address of the primary Admin Node, and the grid IP address of at least one other Storage Node. If necessary, correct any link configuration issues.
  7. Once you are satisfied that your link configuration changes are working, return the appliance to normal operating mode:
    1. From the StorageGRID Appliance Installer, select Advanced > Reboot Controller.

    2. Click Reboot Controller.
      The appliance reboots and rejoins the grid. This process can take up to 20 minutes.
    3. From the Grid Manager, monitor the status of the upgraded appliance Storage Node.
      Verify that the Storage Node returns to the expected status.
