Run a Scenario from Outside the Wizard

After you create a scenario, you need to run it to start the replication process. Normally, before changes to data on the Master can be replicated on the Replica, the Master and the Replica need to be synchronized. Therefore, the first step in initiating a replication is synchronizing the Master and Replica servers. After the servers have been synchronized, online replication starts automatically, continuously updating the Replica with all of the changes that occur on the Master.

Note: In order for the replication process to succeed, verify that the user under which the Engine is running has Read permission on the Master, and Read and Write permissions on each replication root directory and included files, and on all participating Replica hosts.

To start a scenario:

1. From the Scenario pane, select the scenario you want to run.
2. To run the scenario, click the Run button on the Standard toolbar.

   Arcserve RHA verifies the scenario before running it.

   If the scenario was not set up correctly or problems occurred in the participating hosts, errors are reported on the Event pane.

   Notes:

   • If any errors are displayed, you cannot run the scenario. These errors must be corrected before you can start the replication process.
   • Replication of mount points will succeed 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.

3. From the Run screen, select the following and then click OK:
   • Synchronization Method -- For database and virtual machine applications, Block Synchronization is usually best but for File Servers or other applications with large numbers of small files, choose File Synchronization. See the Arcserve RHA Administration Guide for more information.
   • Ignore same size/time files -- Disable this option for database applications. Enable this option for File Server applications to speed up the comparison process and reduce overall synchronization time. See the Arcserve RHA Administration Guide for more information.
   • Skip Synchronization -- Select this option only if you are certain that the data in the Master and Replica root directories is identical.

The Manager indicates that the scenario is running with a green play symbol to the left of the scenario, and with the scenario's state, which turns into Running:

Once a scenario is running, a Statistics tab appears at the bottom of the Framework pane, displaying a graphical view of the replication.

By default, once synchronization occurs, a Synchronization Report is generated. To view the report, refer to the topic, View a Report.

Note: You can also generate a Replication Report on a regular basis to monitor the replication process on each participating server. For more information, see Arcserve RHA Administration Guide.
