You cannot clear alert messages shown on the LCD display from the TMOS console. In addition, the Alarm LED may continue to reflect an elevated alert status (by display a steady or blinking Red or Amber state) after LCD alert messages are cleared.


The alarm state does not clear. The Alarm LED may indicate a previous alert state that has been acknowledged/cleared and is no longer accurate.


-- This may occur when BIG-IP system is running on hardware platforms other than iSeries appliances. -- Specifically, affected platforms include: + VIPRION B4200, B4300-series, B4400-series blades + VIPRION C4400, C4480, C4800 chassis + VIPRION B2100, B2150, B2250 blades + VIPRION C2400, C2200 chassis + BIG-IP 2000-series, 4000-series, 5000-series, 7000-series, 10000-series, 12000-series appliances + BIG-IP 800, 1600, 1600 LC, 3600, 3900, 6900-series, 8900-series, 11000-series appliances + EM 4000 appliances -- Using the following commands to clear alerts from the LCD display or reset the Alarm LED: tmsh reset-stats sys alert lcd lcdwarn -c <level> [<blade>]


It may be possible to work around this issue using either of the following procedures: -- Clear the LCD alert messages by pressing the appropriate buttons on the front panel LCD display itself. -- Restart the fpdd daemon: bigstart restart fpdd Otherwise, rebooting the BIG-IP system restores the correct LED states.
