For maintenance reasons (for example to deploy new versions of DeviceServer) on a Tango Control System , we use the Stop All server feature of ASTOR.
There is no visual feedback that on a host ALL DeviceServers are really stopped .
In fact a host becomes orange in ASTOR as soon as only 1 DeviceServer is stopped .
The feature would be to add a new color to identify such an host where all DeviceServer are stopped
Implemented in Starter and Astor.
Will be available in next distribution.
