Upload the BIG-IQ software image to the standby BIG-IQ

Upgrade the standby BIG-IQ

Before you can upgrade the standby BIG-IQ system, you must have uploaded the software to it.
The active BIG-IQ is upgraded automatically, directly after the devices in the DCD cluster are finished upgrading, but you have to manually upgrade the standby BIG-IQ system.
Use the following command only in very specific circumstances, such as this one, since it clears the majority of a BIG-IQ system's configuration. Before you run the command, be sure you are on the standby BIG-IQ system. This command removes all stored data. If you run this command from the active BIG-IQ system, you'll permanently lose all of your saved data.
  1. Log in to the standby BIG-IQ system's command line as
    root
     and type the following command:
    /usr/bin/clear-rest-storage
    .
    While this step is not required, it clears the database storage on the system so the upgrade goes more quickly. After you upgrade both peer systems and re-establish the HA pair, the peer BIG-IQ will synchronize its database with this BIG-IQ system and repopulate the database.
  2. Log in to the system that you are going to establish as the standby BIG-IQ system's user interface.
  3. At the top of the screen, click
    System
    .
  4. On the left click
    SOFTWARE MANAGEMENT
    Software Installations
    .
  5. Click
    Upgrade
    .
  6. For the Software Image, select the image you want to install.
  7. From the
    Target Volume
     list, select the volume you want to install the image on.
    You can either choose an existing (inactive) volume, or create a new volume. If the
    Target Volume
     list is empty, the machine you are upgrading does not have a second volume available for you to install the upgrade. You must create one to proceed.
    • To install to an existing volume, select
      Target Volume
       and select the volume for the upgrade.
    • To install to a new volume, select
      New Volume
      , and type the new volume name.
  8. To back up the BIG-IQ device, select
    Backup the BIG-IQ System before upgrade
    .
  9. Click
    Install
     at the bottom of the screen.
Wait while the BIG-IQ standby device upgrade process completes. During this time, it is important that you not interrupt the installation process by restarting services or the server. When the BIG-IQ upgrades, it becomes inaccessible briefly. When you can log in to the BIG-IQ again, the process is complete.
