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
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 video after Archiver failover in Security Center.
- On the primary Archiver server, open the Server Admin.
Select the primary Archiver server and click
Expand Archiver Role commands and click
- To enable the ForceExecutionOnPrimary option, type true and click OK.
If the operation is successful, you receive a Succeeded
- Repeat the steps for each server that hosts an Archiver role that manages a decoder.
