Accessing K2 Media Server features in the K2Config application
In the K2 System Configuration (K2Config) application , features for working on a K2 Media Server
are as follows:
Taking a K2 Media Server out of service
This procedure applies to K2 Media Servers that are taking the role of media file system and metadata
server.
When you take a K2 Media Server out of service you stop services such that the K2 Media Server
is prevented from functioning as a media file system and/or metadata server. In this state no media
operations can take place.
If there is just one K2 Media Server in the role of media file system and metadata server, before
you take the K2 Media Server out of service, you should stop all media access on the K2 SAN.
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.
