Overview

In order to gracefully shut down a Verba server, the server or selected services can be put into maintenance mode. When maintenance mode is activated for a service or for a server, the system will notify all affected services and will gracefully stop the main functionality of the service(s) to prevent data loss or interruption. Maintenance mode is designed to support gracefully draining the resources on a server to be able to move the load to another server in redundant deployment configurations. Once maintenance mode is activated, the user interface shows the actual status of the service and the number of remaining active sessions. Once all active sessions are terminated gracefully, the service enters maintenance mode and can be shut down. The following table summarizes supported Verba services and the effect of activating maintenance mode:

Service Name	Maintenance Mode Description
Verba SfB/Lync Call Filter Service	Once maintenance mode is activated, the service will no longer attempt to start the recording process on new calls and will gracefully wait until all ongoing calls are ended. The service will maintain all active network connections, including the SfB/Lync Server API connection. The call blocking feature is also disabled in maintenance mode.
Verba SfB/Lync IM Filter Service	Once maintenance mode is activated, the service will no longer attempt to start the recording process on new conversations and will gracefully wait until all ongoing conversations are ended. The service will maintain all active network connections, including the SfB/Lync Server API connection. The conversation blocking feature is also disabled in maintenance mode.
Verba SfB/Lync Communication Policy Service	Once maintenance mode is activated, the service will no longer attempt to start controlling (block, filter) new conversations and will gracefully wait until all ongoing conversations are ended. The service will maintain all active network connections, including the SfB/Lync Server API connection.
Verba SfB/Lync Announcement Service	Once maintenance mode is activated, the service will gracefully wait until all ongoing P2P announcements are ended, then it will disconnect from the SfB/Lync Server API and from all Verba Passive Recorder Service. Once the service disconnects from the SfB/Lync Server API, all active conference call connections are terminated. The Verba Passive Recorder Service is able to detect this event and trigger another available Announcement Service to connect to the ongoing conference calls.
Verba Media Collector and Proxy Service	Once maintenance mode is activated, the service will notify all connected Verba SfB/Lync Call Filter Service to stop assigning new calls. The service will gracefully wait until all ongoing calls are finished.
Verba Passive Recorder Service	Once maintenance mode is activated, the service will no longer attempt to start the recording process on new calls and will gracefully wait until all ongoing calls are ended. If the service is connected to Verba Media Collector and Proxy Services, then it will notify them to stop assigning new calls to the recorder.
Verba Unified Call Recorder	Once maintenance mode is activated, the Media Recorder component in the service will no longer attempt to start the recording process on new calls and will gracefully wait until all ongoing calls are ended. The service will notify all connected Verba Recording Director components to stop assigning new calls to the recorder. The Recording Director component of the service will refuse any new connection or call setup attempt from the recorded platforms (for instance sending SIP BUSY), but will gracefully wait until all ongoing calls are terminated.
Verba Cisco Compliance Service	Once maintenance mode is activated, the service will no longer attempt to start controlling (record, block, filter) new conversations and will immediately stop recording/filtering all ongoing conversations. The service will close all EventBroker API connections with the CUPS servers.

Start maintenance mode

To activate maintenance mode, follow the steps below:

Step 1 - Using the web application, navigate to the Administration / Verba Servers page.

Step 2 - Select the server where maintenance mode needs to be activated.

Step 3 - Click on the Service Control tab.

Step 4 - Click on the button to start the maintenance mode for the service or for all services supporting the feature on the server.

Step 5 - Wait until the service enters maintenance mode after gracefully ending its normal operations. Once the service is in maintenance mode, the service can be stopped and/or disabled.

Stop maintenance mode

To stop maintenance mode, follow the steps below:

Step 1 - Using the web application, navigate to the Administration / Verba Servers page.

Step 2 - Select the server where maintenance mode needs to be stopped.

Step 3 - Click on the Service Control tab.

Step 4 - The service has to be started first if it is not running.

Step 5 - Once the service is running, click on the button to stop the maintenance mode for the service or for all services supporting the feature on the server.

Step 6 - Wait until the service enters normal mode.
