Chapter 14 Administering and maintaining the K2 Storage System
If there is just one K2 Media Server in the role of media file system and database
server, before you take the K2 Media Server out of service, you should stop all media
access on the K2 Storage system.
If there are redundant K2 Media Servers currently in service (both primary and
backup) in the role of media file system and database 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. Refer
to “Triggering an intentional failover” on page 477 . 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/database server currently in service. You can then
take the primary K2 Media Server out of service without triggering a failover
event.
Also refer to “Using the Stop button in Server Control Panel” on page 481 .
To take a media file system/database K2 Media Server out of service, do the
following:
1. Stop all media access on the K2 Storage System.
2. In the K2 System Configuration application tree view, select the K2 Storage
System.
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.
Refer to the explanation earlier in this section and to
“Triggering an intentional
failover” on page 477 .
Also refer to the next section “Using the Stop button in Server Control Panel” to
consider 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. As specified in the next section “Using the Stop
button in Server Control Panel” , 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.
