Modifying K2 Media Server network settings
Read the following sections for considerations and procedures for modifying network settings on a
K2 Media Server.
Whenever you modify control network settings or FTP/streaming network settings on any device,
you must then redeploy the hosts le if that is your name resolution mechanism.
Modifying K2 Media Server control network settings
If the K2 Media Server takes the role of media le system and metadata server, modifying its control
network settings on an existing K2 SAN is not supported as a customer procedure. This is because
the network identity of the K2 Media Server is embedded throughout the K2 SAN. To recongure
this network identity, you must recongure the entire system from the start. Contact your Grass
Valley representative for assistance.
Modifying K2 Media Server FTP network settings
You can modify the FTP network settings using SiteCong without directly affecting the media le
system or metadata service. However, you must be aware of the requirements of your site’s FTP,
le transfer, and streaming system design, as the FTP network settings will likely need to be changed
elsewhere.
After modifying FTP network settings using SiteCong, open the Network Conguration page in
the K2Cong application. The settings should automatically update. Verify that the settings are
correct.
Modifying K2 Media Server media network settings
Use this procedure if you must change the IP address assigned to an iSCSI interface board on a K2
Media Server. This should not be necessary for a normally operating system and in fact it should
be avoided if possible.
1. Put all the devices of the K2 SAN in an ofine or out of service state. Refer to the appropriate
procedures in this chapter.
2. Open the K2 System Conguration (K2Cong) application on the control point PC.
3. In K2Cong, make sure you know the load balancing bandwidth parameters for each of the
iSCSI clients, as you must re-enter these values later in this procedure.
4. In K2Cong, remove all iSCSI clients from the K2 SAN. To do this, select each iSCSI client
and click Remove.
5. Use SiteCong to change the IP address. Make sure that the IP address is within the range
designated for the network.
6. Restart the K2 Media Server.
7. In the K2Cong tree view, expand the node for the media server that has the iSCSI interface
adapter for which you need to change the IP address and click the iSCSI Bridge node. The iSCSI
Bridge Server conguration page opens.
8. In K2Cong, identify the iSCSI adapter for which you are changing the IP address. Since you
changed it in SiteCong, K2Cong should now display the new IP address.
