Severity: 3-Major


Following a firmware update, the LCD on iSeries platforms can get stuck continuously displaying the firmware update warning screen.


LCD displays the firmware update screen indefinitely. The LCD cannot be used while it is frozen on the firmware update warning screen.


This occurs following a firmware update, which is typically associated with upgrading to a newer BIG-IP software version.


Important: Before attempting this workaround, check that there are no indications the system is still performing a firmware update (such as a terminal prompt), and that the following messages can be found in /var/log/ltm after the most recent boot: notice chmand[6302]: 012a0005:5: firmware update succeeded. notice chmand[6302]: 012a0005:5: Firmware check finished. These messages indicates that the firmware update has finished, and the LCD is displaying the warning screen in error, so it is safe to perform the workaround. Reboot the BIG-IP system to return the LCD to normal operation.
