# Disable the IDOL Servers

You can use the `EngineManagement` action to dynamically take child servers offline (without restarting the HPE DIH). Send the `EngineManagement` action with the `EngineAction` parameter set to `Edit` and the `Disabled` parameter set to `True` to temporarily disable a child server of the HPE DIH:

    http://DIHhost:ACIPort/action=EngineManagement&EngineAction=Edit&ID=1&Disabled=True

This action disables the server with ID `1`. When a child server is disabled, the HPE DIH continues to assign documents and queue index actions. It does not attempt to send them until you enable the server again, by sending another `EngineManagement` action. For example:

    http://DIHhost:ACIPort/action=EngineManagement&EngineAction=Edit&ID=1&Disabled=False

This behavior is identical to when the HPE DIH has lost contact with one of its child servers. It allows you to manually take a child server offline for maintenance.
