recommended if the system is currently online with media access underway. The additional load
on network and local system resources could cause unpredictable results.

1. If you have not already done so, connect keyboard, monitor, and mouse to the K2 Media Server

and log on to Windows.

2. If Server Control Panel is not already open, on the Windows desktop, click

Start | Grass Valley

| Server Control Panel

.

3. Log on to Server Control panel with administrator-level permissions. The Server Control Panel

opens.

4. Determine if the local machine is currently the primary K2 Media Server or the backup K2 Media

Server.

If the K2 SAN does not have redundant servers, only one server (the left half of the Server Control
Panel) is displayed.

For the K2 Media Servers of a Nearline K2 SAN, Server Control Panel on the local K2 Media
Server reports if the server is the current active media file system (SNFS) server. No metadata
information is displayed, since the Nearline system does not have a media database.

Triggering an intentional failover

WARNING: Do not attempt this procedure except under the supervision of qualified Grass
Valley personnel.

The following procedure renders the primary K2 Media Server unqualified to carry out its role in
managing the K2 SAN. The backup K2 Media Server detects this condition and triggers a failover
in which it takes the primary server out of service and takes control of the K2 SAN. Therefore,
before using these procedures, verify that the backup K2 Media Server is fully operational and
qualified to take control of the K2 SAN. Be aware that the failover capabilities of the -K2 SAN are
degraded until you place the machine back into service as the backup K2 Media Server.

You should stop all media access before attempting this procedure. If media access is underway,
there will be period of time in which media loss will occur.

In the following procedures, K2server1 and K2server2 represent your redundant K2 Media Servers.
The procedure begins with K2server1 acting as the primary K2 Media Server.
