Short Description

Perform autonomous F5 LTM upgrades with python

Using a single python script to Automate F5 LTM's deployed as a High Available Pair

Problem solved by this Code Snippet

• the script gathers ucs and qkview from both the device pairs and uploads to an SFTP server defind by environment variables
• it then gathers the state of all the VIPs and Pools from both device pairs and stores the files locally
• It stores the state of the active volumes from both devices
• it identifies the active device and saves the running config and does a verify load to check for config errors
• it then proceeds to find the standby device and install the image on a inactive volume
• once installation of image is complete it proceeds to reboot to volume with new image
• once the device is up and the mcpd is up, it checks the state of vips/pools with the pre-check, if there are differences it stops the upgrade, if no differences are identified it proceeds with the next device
