Unable to Damp Violin Mode 9
   Violin mode-9 (ETM-X)is ringing up, and am unable to damp it. Guardian message is to turn off gain, however the gain on the filter bank is 0.000. When I try to change the gain, Guardian (I assume) is overriding my changes and putting it back to zero. 

   Looking at the Guardian VIOLIN_MODE.STATE screen, there is a state to turn off the DAMPING for a suspension, but not the gain. 

   Could find no information in the WIKIs or in the aLOG that addresses this situation. Leaving the IFO in Observation mode and hoping a commissioner comes in before it breaks lock.
