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.
Identifying K2 Media Server software versions
Your options for identifying K2 Media Server software versions are as follows:
• In NetCentral, select the Facility button, then in the tree view open the node for the
K2 Media Server. This exposes the subsystems. You can find software version
information on property pages for the
Software subsystem and the Roles
subsystem.
• In the K2 System Configuration application tree view, open the node for the K2
Media Server. This exposes the nodes for individual configuration pages. Select
the
Software configuration page to view software version information. To check for
recent changes in software, click the Check button.
• Use SiteConfig software deployment features.
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 file if that is your name resolution
mechanism.
Modifying K2 Media Server control network settings
If the K2 Media Server takes the role of media file 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 reconfigure this network identity, you must
reconfigure 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 SiteConfig without directly affecting
the media file system or metadata service. However, you must be aware of the
requirements of your site’s FTP, file transfer, and streaming system design, as the FTP
network settings will likely need to be changed elsewhere.
After modifying FTP network settings using SiteConfig, open the Network
Configuration page in the K2 System Configuration application. The settings should
automatically update. Verify that the settings are correct.
