4. Allow the failover process to complete, until K2server2 is operating correctly in its new role as
the primary K2 Media Server for the K2 SAN.
5. Verify K2server2 as primary.
6. Start up K2server1. It is now out of service. If you need to do service work on K2server1, you
can do it now. After your work is complete, proceed with the next step.
7. If there are K2 Media Servers with role of iSCSI bridge or Fibre Channel switches on the same
redundant “side” as K2server1, start or restart them.
8. In Server Control Panel, for K2server1, click Start . This notifies K2server2 (via a heartbeat signal
on the serial cable) that K2server1 is coming online as backup.
9. Verify K2server1 as backup.
10. All failover processes are complete. All media management mechanisms are now running and
K2server1 is now qualified and acting as the backup.
Recovering from a failover
WARNING: Do not attempt this procedure except under the supervision of qualified Grass
Valley personnel.
In the following procedures, K2server1 and K2server2 represent your redundant K2 Media Servers.
The procedure begins with K2server1 being the server on the failed side of the SAN. K2server2 is
acting as the primary K2 Media Server.
1. Verify primary/backup roles and make sure K2server2 is the primary.
2. Start up K2server1. It is now out of service.
3. Determine the cause of the failover and take corrective action as necessary. If you need to do
service work on K2server1 or other devices on the failed side of the SAN, you can do it now.
After your work is complete, proceed with the next step.
4. If there are K2 Media Servers with role of iSCSI bridge, Ethernet switches, or Fibre Channel
switches on the same redundant “side” as K2server1, start or restart them. Make sure they have
been started up at least once before putting K2server1 into service.
5. In Server Control Panel, for K2server1, click Start . This notifies K2server2 (via a heartbeat signal
on the serial cable) that K2server1 is coming online as backup.
6. Verify K2server1 as backup.
7. All failover processes are complete. All media management mechanisms are now running and
K2server1 is now qualified and acting as the backup.
