Affected Product(s):
F5OS F5OS-A, Install/Upgrade
Known Affected Versions:
F5OS-A 1.7.0
Opened: May 03, 2024 Severity: 3-Major
When the OS on a system is downgraded (For example, from F5OS-A 1.7.0 to F5OS-A 1.5.2), the LCD may no longer report the system’s hostname and management IP address. It may also continue to report the OS version prior to the downgrade.
No functional impact. The hostname, management IP address, and OS version are correctly reported by ConfD or through the GUI.
When a rSeries appliance OS has been downgraded (For example, from F5OS-A 1.7.0 to F5OS-A 1.5.2).
When the OS is downgraded on a system, the LCD UI does not automatically revert to the version provided by the downgraded OS. As a result, some LCD UI features may no longer be available after the downgrade. To force the LCD UI to be downgraded, follow these steps: 1) Log in to the system as a root user. 2) At the Linux prompt, issue the following command: `docker exec -it platform-fwu psf call PUT:firmware/lcd/ui updatePolicy=different`. 3) Wait 60-90 seconds for the LCD UI update to complete. 4) At the Linux prompt, issue the following command: `docker exec -it platform-hal psf call POST:lcd/reboot waitForBootup=true`. 5) Wait 60-90 seconds for the LCD to complete a reboot. A clean install in the lower version of F5OS-A, for example, 1.5.2, may also restore the functionality of the new lcd-ui firmware.
