Monitoring and Controlling the Broadcast
Performing a manual failover to a backup channel
resynchronized with the main channel by using the Resync button on the Channel Control
page. The Resync button triggers the backup device to obtain a fresh copy of the main
channel’s playlist from GV STRATUS Playout. For more information about backup channels,
see
Implementing high availability for channels (channel failover) , on page 39.
To resync the backup channel:
1 In the top menu, click Channel Control.
2 In the Channels list, click the name of the backup channel that you want to resync.
3 Click Resync.
Performing a manual failover to a backup channel
To provide high availability for a channel, you can have two channels set up as a main and
backup pair. Each channel is assigned to a device to support failover between the devices in
case of a card failure or other failover condition on the on air channel. The SSP-3801 cards
associated to the devices may also be connected to an HCO device, which provides an
automatic method for managing the failover between the devices, or other system which
handles the routing of the playout from the main to the backup. For more information
about backup channels, see
Implementing high availability for channels (channel failover) ,
on page 39.
When the SSP-3801 cards associated to the devices are connected to an HCO device, the
HCO device should be in Auto Failover Mode so it can automatically perform the failover
from the main device to the backup when a failure condition occurs. If you choose to
manually perform the failover, it forces the HCO device into Manual Failover Mode. You can
also switch to Manual Failover Mode without performing a failover by just clicking the HCO
button. This might be useful when you are performing maintenance on the backup device
since having it in Manual Failover Mode will prevent the automatic switching from the main
to the backup before the backup is ready. It is important, however, to remember to return
the HCO device to Auto Failover Mode once the maintenance is finished.
If the SSP-3801 cards associated to the devices are not connected to an HCO device, then
the procedure for handling the failover depends on how your system is configured and it
may require that you perform the failover manually.
To perform a manual failover to the backup channel:
1 In the top menu, click Channel Control.
2 Resynchronize the backup channel with the main channel. For more information, see
Resynchronizing a backup channel , on page 97.
3 In the Channels list, click the name of the channel on which you want to perform the
failover.
4 Click Failover.
5 Perform the required maintenance on the device that experienced the failover
condition.
6 When the device is ready, you can perform the manual failover from the backup
channel back to the main channel by selecting the name of the backup channel in the
Channels list and clicking the Failover button.
7 If the SSP-3801 cards associated to the devices are connected to an HCO device, you
must reset the devices to Auto Failover Mode. Click the HCO: Manual button.
