This is how the SimulationMode property can be changed or listed:
$ TngUtility.py --simList List the SimulationMode property of all devices. $ TngUtility.py --simList dgg mca List the SimulationMode property of selected devices. $ TngUtility.py --simOn Sets the SimulationMode property of all devices to 1. $ TngUtility.py --simOn dgg mca Sets the SimulationMode property of the selected devices to 1. $ TngUtility.py --simOff dgg mca Sets the SimulationMode property of the selected devices to 0.
Notice that the servers have to be restarted in order to let property changes come into effect.
