Configuring HA

Note:

To configure HA between two devices, the devices must meet certain minimum requirements. For details, see HA Requirements.

  1. Determine which of the two devices to set up as the active node.
  2. Power on the active and standby node devices.
  3. Connect the active and standby node devices to the same network.
  4. Initialize the active node device.
  5. Optional: Initialize the standby node device.
    Tip:

    You can also let HA Manager initialize the standby node device later.

  6. Prepare the pairing process.
    1. Log on to QNE on the active node.
    2. Install HA Manager.

      For details, see Installing HA Manager.

    3. Open HA Manager.

      The Welcome to High Availability (HA) Manager screen appears.

    4. Click Start.

      The HA Requirements screen appears.

    5. Read the HA requirements.
    6. Click Next.

      The Configure the Standby Node Device screen appears.

    7. Enter the IP address of the standby node device using one of the following methods:

      • Type in the IP address of the standby node device.

      • Click and select the standby node device from the network list.

    8. Answer the following question and follow the relevant steps.

      Is the Standby Node Device Initialized?

      User Action

      Yes

      1. Enter a username and password of the standby node device.

      2. Click Next.

      No

      1. Leave the username and password fields blank.

      2. Click Next.

        A confirmation window for initializing the standby node device appears.

      3. Click Yes.

        The Initialize the Standby Node Device screen appears.

      4. Enter a hostname for the standby node device.

      5. Click Start.

        A confirmation window appears.

      6. Click Confirm.

        The system initializes the standby node device. This process may take some time.

      7. Click Next.

      The system checks whether HA Manager is installed on the standby node device.

      The system installs HA Manager on the standby node device if the application is not yet installed. This process may take some time.

    9. Click Next.

      The HA Device Pairing screen appears.

  7. Pair the active and standby node devices.
    1. Check the specification comparison between the active and standby node devices.
    2. Optional: Click Back and make adjustments and/or replacements to ensure specification consistency between the two devices.
    3. Click Next.

    The HA Link Configuration screen appears.

  8. Set up the network.
    1. Select a minimum 10 Gigabit network port on each device as the HA link port.
      Important:

      Both devices must use the same port number for the HA link.

    2. Connect the HA link port on the active node device to the HA link port on the standby node device with a minimum 10 Gigabit network cable.
    3. Select the connected HA link ports.
    4. Click Next.

      The Management Port Configuration screen appears.

    5. Select a port on each device as the management port.
      Important:

      • The management port on each device must be a native port, and must be configured with a static IP address.

      • Both devices must use the same management port number.

    6. Connect the management port on the active node device to the network (if not already connected).
    7. Connect the management port on the standby node device to the network (if not already connected).
    8. Select the connected management ports.
    9. Click the active node management port to configure a static IP address for the port.
    10. Click the standby node management port to configure a static IP address for the port.
    11. Click Next.

      The Configure Virtual IP Address screen appears.

    12. Optional: Select Enable virtual IP address and enter your virtual IP address and subnet mask.
      Note:

      Setting up a virtual IP address allows you to maintain a constant connection to the active node no matter which device becomes the active node after a failover or switchover.

    13. Click Apply to enable the virtual IP address, or click Cancel to set it up later.

      The HA Settings Summary screen appears.

  9. Create the HA environment.
    1. Optional: Edit the standby node hostname.
    2. Optional: Enter a description for each device.
    3. Optional: Edit the HA group ID.
      Note:

      This field cannot be blank.

    4. Click Create after confirming the HA settings summary.

      A warning message appears.

    5. Select the checkbox to acknowledge all data on the standby node device will be deleted.
    6. Click Yes to start creating the HA environment.
      Important:

      Ensure power stability during the process.

    7. Wait for HA Manager to reinitialize the standby node device, install applications, and sync the system and application configurations between the node devices.

      A confirmation message appears when the configuration is complete.

  10. Click OK.

HA Manager configures HA between the two devices.

You can configure additional settings in HA Settings > Policies.
