Grass Valley K2 Summit Storage Area Network Installation - Manual (Page 286)

If there are redundant K2 Media Servers currently in service (both primary and backup) in the role
of media file system and metadata server, take only the backup out of service. Do not take the
primary out of service. If you take the primary out of service it will trigger a failover event. If the
K2 Media Server that you want to take out of service is currently the primary, you have the following
options:
• Make the current primary K2 Media Server the backup in an orderly fashion by triggering an
intentional failover. Then, when the K2 Media Server is the backup, you can take it out of service.
• Take the current backup out of service (shutdown) so that the primary K2 Media Server is the
only file system/metadata server currently in service. You can then take the primary K2 Media
Server out of service without triggering a failover event.
1. Stop all media access on the K2 SAN.
2. In the K2Config application tree view, select the K2 SAN.
3. Select Server Control Panel . The Server Control Panel opens.
4. Identify the K2 Media Server you intend to take out of service. If there are redundant K2 Media
Servers, consider that you might trigger a failover event.
Use the Stop button in Server Control Panel as appropriate for the action that you want to take.
5. When you are sure that you understand the implications of taking the K2 Media Server out of
service, click the Stop button for that server.
6. Proceed as follows:
• If the server shuts down automatically, allow the shutdown processes to complete. Then start
the server. When a redundant server restarts, it comes up in an out of service state.
• If the server continues to run, it is in an out of service state.
