Using the Buddy Update

This method uses the buddy update feature of IGEL Linux. One or more devices that are configured as an update buddy access the main server and download the firmware. The other devices are configured to download their firmware from an update buddy.

Checking the Requirements

Configuring Two Update Buddies

For setting up buddy updates, see the How-To Buddy Update.

  1. Update one device to IGEL Linux v5.11 and configure it as an update buddy.
  2. Upgrade another device to IGEL Linux 10, or take the one from Testing the Upgrade, and configure it as an update buddy. Make sure that the IGEL Linux 10 update buddy has the same User Name and Password in System > Update > Buddy Update as the IGEL Linux v5.11 update buddy.

Creating a Profile for the Upgrade

  1. Create a profile based on IGEL Linux 5.11.200. Find a suitable name for the profile, e.g. "Allow firmware upgrade to IGEL Linux 10".
  2. In the profile's configuration dialog, navigate to System > Update > Firmware Update and change the settings as follows:

    In UMS version 5.05.100, the screen should look as shown below:

  3. If you have UMS version 5.04.100, go to System > Registry > update and activate the force_firmware_migration parameter.

    The screen should look as shown below:

4. Click Save.

Putting It All Together

  1. Assign the profile to all devices that are to be upgraded. This can be done by assigning the profile to the directory that contains these devices.

    Do not assign the profile to the update buddies. In this way, the update buddies remain intact and can be used again if some devices need a second attempt.

  2. In the context menu of the assignment, select Now.

    The directory and its assigned objects should look as shown here:

Executing the Upgrade

  1. In the UMS, select all devices that are to be upgraded and reboot them.

    You can create a scheduled job for the reboot and assign it to the devices or the directory containing these devices. For more information, see Tasks.

    On reboot, the devices choose the IGEL Linux 5.11 buddy; they ignore the IGEL Linux 10 buddy at this stage because this version is not known to them yet. When the devices are powered up, they look for an update buddy again because the parameters Automatic Update Check and Automatic Buddy Detection are still activated. Additionally, the devices now recognize the Allow firmware upgrade to IGEL Linux 10 parameter; this is due to their update to IGEL Linux 5.11. Because this parameter is set, the devices wait for an IGEL Linux 10 update buddy to reply. When an IGEL Linux 10 update buddy is found, the devices download the new firmware and start the upgrade process.

    For a detailed description of the upgrade process from IGEL Linux v5.11 to IGEL Linux 10, see Testing the Upgrade.

  2. When all devices have been upgraded successfully, remove the "Allow firmware upgrade to IGEL Linux 10" profile and the two update buddies from the directory.
