Distributed Index Handler 25.4

# Disabled

Set to `true` to disable the child server specified by the ID parameter.

When a child server is disabled, the Distributed Index Handler continues to assign documents to it, and queue up index actions, but it does not attempt to send them until the child server is enabled again. This behavior is identical to when the Distributed Index Handler has lost contact with one of its child servers.

You can enable a child server by sending another EngineManagement action, with the `Disabled` parameter set to `false`.

Setting `Disabled` to `true` for a child server allows you to take it offline for maintenance.

NOTE: By default, when you add a child server by setting EngineAction to `add`, the DIH pings the specified Host and Port and the add action fails if the child server is not running. You can set `Disabled` to `true` to skip this step and add the child server in the disabled (offline) state.
