Monitoring connections
When a source is highlighted in the left pane of the Management Console, the connections and their
statistics are displayed in the right pane. Additionally, colors and icons are used for the connections,
and the Storage Mirroring servers, to help you monitor your connections. Review the Connection
Statistics and Connection and Server Display tables for statistics and status descriptions. (Statistics
marked with an asterisk (*) are not displayed, by default.)
Connection Statistics
Statistic Description
Replication Set Replication set indicates the name of the connected replication set.
Connection ID The connection ID is the incremental counter used to number each
connection established. This number is reset to one each time the Storage
Mirroring daemon is restarted.
Target Name The name of the target as it appears in the server tree in the left pane of the
Management Console. If the server’s name is not in the server tree, the IP
address will be displayed.
Target IP The target IP is the IP address on the target machine where the mirroring
and replication data is being transmitted.
Target Data State
 OK—The data on the target is in a good state.
 Mirroring—The target is in the middle of a mirror process. The data will
not be in a good state until the mirror is complete.
 Mirror Required—The data on the target is not in a good state because
a remirror is required. This may be caused by an incomplete or stopped
mirror or an operation may have been dropped on the target.
 Restore required—The data on the source and target do not match
because of a failover condition. Restore the data from the target back to
the source. If you want to discard the changes on the target, you can
remirror to resynchronize the source and target.
Target Status
 OK—The target machine is active and online.
 Not Loaded—The target module is not loaded on the target. (For
example, the activation code is invalid.)
 Paused—The target machine is paused by user intervention.
 Retrying—The target machine is retrying operations for the connection.
This field may not be updated until there is source/target activity.
Commit Mode * The commit mode status indicates the connection status.
 Real-time—Data is being transmitted to the target machine in real-time.
 Scheduled—Data is waiting to be transmitted to the target machine until
one or more transmit options have been met.
Transmit Mode
 Started—Data is being transferred to the target machine.
 Paused—If the transmission is real-time and the transmission has been
paused, the Transmit Mode indicates Paused.
 Scheduled—If the transmission is scheduled, the Transmit Mode
indicates Scheduled.
 Stopped—Data is not being transferred to the target machine.
 Error—There is a transmission error.
