Note:
When adding a new Recorder to RM’s database, the Recorder’s database will be reset so that RM
can configure it from an empty database with default values. This process may take a few
minutes.

level
Redundancy
In record-level redundancy, a Primary and Redundant Recorder are configured to provide active-muted
redundant recording from the RM. Both Recorders are concurrently recording content received from
the transcoder, but only one recording at a time is written to the storage server for JITP delivery. If a
Recorder fails to write content to the storage server, then the redundant Recorder will pick up in its
place and continue to write the content to the storage server.
Note:
A Recorder is a Packager that is licensed for recording. When you configure the
Recorders
tab in
the RM, you are in effect configuring a specific type of package on a Packager.
In essence, record-level redundancy from the RM works in the same manner that package-level
redundancy works on a Packager, with one exception: in record-level redundancy, the Recorders are not
writing content to the storage server at the same time; rather, they are recording content at the same
time, but only one Recorder writes the content to disk at a time.
Master/Slave
Behavior
In record-level redundancy, reference timing control is based on a first-come first-serve basis. The
redundant recording that starts first effectively becomes the ‘master’ record, on which the ‘slave’
Primary Status
Indicates the operational status of the Primary Recorder. One of three
status indications will be displayed:
OK - Good connectivity, Recorder is operational
SET FAILURE - No connectivity, Recorder is disabled
DISABLED - There is connectivity, but Recorder is disabled for another
reason.
n/a
Primary IP Address
Specifies the IP address of the Recorder.
Empty
Redundant Status
Indicates the operational status of the redundant Recorder (if it has
been configured). One of three status indications will be displayed:
OK - Good connectivity, Recorder is operational
SET FAILURE - No connectivity, Recorder is disabled
DISABLED - Recorder is disabled due to either no redundant node
being configured or another type of redundancy failure.
n/a
Redundant IP
Address
Specifies the IP address of the redundant Recorder. Recorder
redundancy is enabled as soon as the redundant IP address is
configured and connectivity is established.
