Placing a K2 Media Server in service
This procedure applies to K2 Media Servers that have the role of media file system and metadata
server.
When you put a K2 Media Server in service it is capable of taking the role of media file system and
metadata server.
1. In the K2 System Configuration application tree view, select the K2 SAN.
2. Select Server Control Panel . The Server Control Panel opens.
3. For the K2 Media Server that you want to place in service, click the Start button.
Shutting down or restarting a K2 Media Server
• To shut down or restart a K2 Media server that is in the role of media file system and metadata
server, first put the server out of service, as explained in the procedures earlier in this section.
Then you can shut down or restart the K2 Media Server.
• To shut down or restart a K2 Media server that is not in the role of media file system and metadata
server, consider that the K2 Media Server can host the iSCSI interface adapters (TOEs) by which
clients access the shared storage. You should stop all media access before shutting down or
restarting any K2 Media Server that hosts an iSCSI interface adapter.
