A key feature of BIG-IQ® is the ability to manage software images for multiple remote devices from one location. You can deploy software without having to log in to each individual BIG-IP® device.
There are three steps to managing software images for devices:
Downloading a software image from F5 Networks is the first step to making it available to install on a managed device.
You upload a software image to make it available to deploy to managed BIG-IP® devices.
Before you can install a software image onto a device, you must download it from the F5 Downloads site, https://downloads.f5.com, and upload it to the BIG-IQ® system. To apply a hotfix, you must have the base software image (as well as the hotfix) uploaded to, and verified by, BIG-IQ.
Install software images to your managed devices so the versions are up to date, and in sync. This helps you manage your network traffic more efficiently. When you install software images from BIG-IQ, you have the option to stage the software installation for deploying later, as well as the option to have the installation paused after the software image is copied to the device and before the device reboots. While the software installs on the BIG-IP devices, you can continue doing other tasks on the BIG-IQ system.
Pause after the software image is copied has been copied to devices.
Pause for reboot confirmation.
If you selected an option save the deployment or to pause the process at certain points, click the name of the software installation on the Software Installation list, and click the Continue button when you're ready to continue the software installation.
To properly communicate, BIG-IQ® and BIG-IP® devices must be running compatible versions of the REST framework. If the REST frameworks are incompatible, BIG-IQ displays a yellow triangle next to the device in the BIG-IP Device inventory.
When you upgrade a BIG-IP® device running version 11.5.x to another 11.5.x version, or to an 11.6.x version (for example, from version 11.5.3 to 11.5.4, or from version 11.5.3 to version 11.6.1), you must upgrade the REST framework so BIG-IQ can manage the device. If you upgraded BIG-IQ from version 4.6.0 to version 5.0, you must also upgrade the REST framework for all BIG-IP devices (not running version 12.0.0) currently in the BIG-IP Device inventory.
A BIG-IP® device running versions 10.2.0 - 11.4.1 is considered a legacy device. You must upgrade a legacy device to version 11.5.0 or later before you can add it to the BIG-IP Device Inventory and start managing it from BIG-IQ.
If you were managing a device running versions 10.2.0 - 11.4.1 from a previous version of BIG-IQ, and upgraded to version 5.0, the device displays as impaired with a yellow triangle next to it in the BIG-IP Devices Inventory. To manage the legacy device, you must upgrade it to 11.5.0 or later.
