<p>Changes the state of a file transfer protocol-enabled server from <code>OFFLINE</code> to <code>ONLINE</code>. It has no impact on a server that is already <code>ONLINE</code>. An <code>ONLINE</code> server can accept and process file transfer jobs.</p> <p>The state of <code>STARTING</code> indicates that the server is in an intermediate state, either not fully able to respond, or not fully online. The values of <code>START_FAILED</code> can indicate an error condition.</p> <p>No response is returned from this call.</p>
