To prevent decoders from losing video after an Archiver failover event, you must
perform some configuration steps after adding the decoders in Config Tool.
What you should know
This procedure is only required if Archiver failover is configured on your
system.
If you have not performed the procedure and the Archiver role fails over,
all monitors connected to decoders turn black when the primary Archiver server comes
back online. If the primary Archiver server is already back online and your
video is black, see [KBA-79028] Decoders stop displaying
videoafter Archiver failover in Security Center.
Procedure
-
On the primary Archiver server, open the Server Admin.
-
Select the primary Archiver server and click .
-
Expand Archiver Role commands and click
ForceExecutionOnPrimary.
-
To enable the ForceExecutionOnPrimary option, type
true and click OK.
-
If the operation is successful, you receive a Succeeded
message.
-
Repeat the steps for each server that hosts an Archiver role that manages a
decoder.
Results
New decoders that you add in Security Center will not lose video after an Archiver
failover event. If you change the primary Archiver server for an Archiver role, you must
perform the procedure again.
