When a firmware image upgrade occurs, it may upgrade the configuration. The new configuration is automatically saved on the flash drive. This allows the administrator to roll back the firmware image and reboot using the old configuration.

Upgrade patch set

A patch set upgrade only includes bugfixes and minor improvements. It has no impact on the configuration.

Upgrade Aloha firmware

  1. Get your ALOHA current model.

  2. Download the new firmware image.

  3. Connect to the Master ALOHA and force a configuration synchronization to the Slave.

  4. Save the configuration on both ALOHA Master and Slave.

  5. On the Slave ALOHA:

    • Open the Setup tab.

    • Scroll down the Setup page to the firmware area.

    • Click on Browse and point to the downloaded firmware.

    • Click on Update.

    • Click on Reboot.

  6. After the Slave reboots, check its status.

    If it looks normal, you can increase its VRRP weight as follows:

    • In the Services tab, click on the Edit icon from the Network line.

    • Update the vrrp prio number to be greater than the current Master value.

    The ex-Slave is now Master and handles the traffic.

    Wait a few hours. In case of issues:

    • You can lower the ex-slave VRRP weight to bring back the ex-master to production

    • A rollback is still possible

  7. If everything looks normal, upgrade the Master ALOHA:

    • Open the Setup tab.

    • Scroll down the Setup page to the Firmware area.

    • Click on Browse and point to the downloaded firmware.

    • Click on Update.

    • Click on Reboot.

  8. After the Master reboots, check its status.

    If it looks normal, you can decrease the VRRP weight from the Slave ALOHA to the prior value as follows:

    • In the Services tab, click on the Edit icon from the Network line.

    • Update the vrrp prio number to the value before the upgrade.

  9. Save the configuration on the Slave ALOHA.

  10. Save the configuration on the Master ALOHA.

Upgrade a minor or major branch

Upward compatibility is guaranteed for both major and minor upgrades. But this upgrade may modify your running configuration in the background.

  1. Get your ALOHA current model.

  2. Download the new firmware image.

  3. Connect to the Master ALOHA and force a configuration synchronization to the Slave.

  4. Save the configuration on both ALOHA Master and Slave.

  5. On the Slave ALOHA:

    • Open the Setup tab.

    • Scroll down the Setup page to the Firmware area.

    • Click on Browse and point to the downloaded firmware.

    • Click on Update.

    • Click on Reboot.

  6. After the Slave reboots, check its status.

    If it looks normal, you can increase its VRRP weight as follows:

    • In the Services tab, click on the Edit icon from the Network line.

    • Update the vrrp prio number to be greater than the current Master value.

    The ex-slave is now Master and handles the traffic.

    Wait a few hours. In case of issues:

    • You can lower the ex-Slave VRRP weight to bring back the ex- aster to production.

    • A rollback is still possible.

  7. If everything looks normal, upgrade the Master ALOHA:

    • Open the Setup tab.

    • Scroll down the Setup page to the Firmware area.

    • Click on Browse and point to the downloaded firmware.

    • Click on Update.

    • Click on Reboot.

  8. After the Master reboots, check its status.

    If it looks normal, you can decrease the VRRP weight from the Slave ALOHA to the prior value as follows:

    • In the Services tab, click on the Edit icon from the Network line.

    • Update the vrrp prio number to the value before the upgrade.

  9. Save the configuration on the Slave ALOHA.

  10. Save the configuration on the Master ALOHA.

Roll back an upgrade

By default, the ALOHA embeds two firmware images: the current running and the one which was running before the last upgrade.

Warning

This procedure only applies when you upgraded a firmware but not yet saved the configuration on the flash drive. It allows you to recover the last ALOHA running state before the upgrade.

Roll back to the last running image

  1. Connect to your ALOHA GUI.

  2. Open the Setup tab and scroll down to the firmware area.

  3. Look at the Next boot image form: the box checked indicates the currently running image.

  4. Check the other box pointing to the old image.

  5. Click on the Update button from the Next boot image firmware.

  6. Click on Reboot
