Managing Replication and High Availability Scenarios › How to Run a Scenario or a Group › Run a Group

Run a Group

You can run multiple scenarios in a group using the following procedure.

To run the group

1. From the Scenario pane, select the group you want to run.
2. Click Run on the Standard toolbar.

   Before initiating synchronization and replication, Arcserve RHA verifies your group configuration. When verification completes successfully, the Manager displays the message: Are you sure you want to run group ‘ group_name' ?

   Note: If problems are discovered, the top pane displays any warning and error messages resulting from verification.

   Group Verification checks many different parameters between the Master and Replica servers to ensure a successful switchover. If any errors or warnings are reported you should not continue until they are resolved.

   If scenario verification reports an error that replicas still exist in the farm, this is due to a configuration error. Launch the SharePoint configuration wizard from the Windows Start menu on the Replica server to disconnect it from the Master's farm and then repeat auto-configuration.

3. Correct errors before you continue. Errors are reported on the Event pane.

   Note: Replication of mount points succeeds only if those were added to the Master before the Engine was started. If you included the mount points in the Master root directories when the Engine was already running, no error is reported but the replication does not start. In this case, you need to restart the Engine on the Master before initiating replication.

   When no error is reported, the Run dialog appears and contains synchronization options.

   Note: Do not use Skip Synchronization for any scenarios replicating a database.

4. If you have a large number of small files, select File Synchronization. If you have large files, select Block Synchronization and if you have a different default synchronization method and run a group, then select Use default ‘Synchronization Method’ for each scenario in this group and then perform synchronization from that device. Select the Ignore same size/time files to skip the comparison of files with the same path, name, size and modification time, which are generally identical, to reduce synchronization time. You should enable the Skip Synchronization option only when you are certain the files on both Master and Replica are identical. (The default selections are File Synchronization and Ignore same size/time files option enabled).
5. Click the OK button. Synchronization may take a while, depending on database size and network bandwidth between the Master and Replica. You will receive the following message in the event window when the synchronization is complete: All modifications during synchronization are replicated.

At this point, the group is operational and active. By default, a Synchronization Report is generated when synchronization finishes. To view the report, refer to the topic, View a Report. You can also generate regular Replication Reports to monitor the replication process on each participating server. For more information, see the Arcserve RHA Administration Guide.
