Create a High Availability Scenario

Create UNIX HA scenarios as you would any other HA scenario, using the Scenario Creation Wizard.

For information about creating an HA scenario for an Oracle database, see the Arcserve RHA Oracle Server Operation Guide.

To create a new UNIX HA Scenario

1. Start Arcserve RHA Manager. Select File, Create, New Scenario or click the New Scenario button.

   The Welcome dialog opens.

2. Click Create a New Scenario and type a Scenario Group Name, or select one from the list and then click Next.

   The Select Server and Product Type dialog opens.

3. Select File Server and ensure the High Availability Scenario (HA) product type is selected. For Tasks on Replica, select None and then click Next.

   The Master and Replica Hosts dialog opens.

4. Type a Scenario Name, enter the Hostname or IP Address and Port number for both the Master and Replica servers, enable the Verify Arcserve RHA Engine on Hosts option, and then click Next. You may be prompted for user credentials. If so, enter the appropriate credentials and click OK.

   The Engine Verification dialog opens if you enabled engine verification.

5. Wait for verification to complete and click Next to continue when it is complete.

   The Master Root Directories dialog opens, showing the list of directories identified on the Master.

6. Click Next.

   The Replica Root Directories screen opens.

7. Set the Replica's directory and click Next.

   The Scenario Properties screen opens.

8. Configure the properties as needed and click Next. For more information about configuring scenario properties, see the Arcserve RHA Administration Guide.

   The Master and Replica Properties screen opens.

9. Configure the properties as needed and click Next. For more information about configuring Master and Replica properties, see the Arcserve RHA Administration Guide.

   The Switchover Properties screen opens.

10. Configure the switchover properties as needed and click Next.

    Note: Recommended default values are already defined. For more information about configuring switchover properties, see the Arcserve RHA Administration Guide.

    1. The Switchover and Reverse Replication Initiation screen opens.
11. Make your selections for the following options to control automatic switchover and automatic reverse replication and click Next.

    Switchover Initiation

    Specifies whether to initiate a switchover automatically or manually. Automatic switchover is initiated when the Master server is down or a database failure is detected. Manual switchover is initiated by the Administrator. In both cases a notification message is provided when a failure is detected.

    Reverse Replication Initiation

    Specifies whether to initiate reverse replication automatically or manually. After a switchover, the scenario stops and reverse replication is initiated.

    Note: It is recommended that you do not set both of these options to automatic in a production environment.

    The Scenario Verification screen opens.

12. Wait while the Scenario Verification process completes.

    If Scenario Verification lists any errors, you must resolve them to continue. If any warnings are listed, you should also resolve them to successfully continue. After making changes, click Retry to repeat verification.

13. Click Next.

    The Scenario Run dialog opens.

14. Click Run Now to start synchronization and activate the scenario. Click Finish to run the scenario later.

For non-global zones on Solaris

Create multiple scenarios in the global zone and then manage all scenarios from there. Most steps are same except the following steps:

1. Enter the global zone IP address as the master IP address.
2. Use the following commands to get the zone and zone root directory information:

   /usr/sbin/zoneadm list -vi
   

   zonecfg -z <zonename> info
   

3. While setting the root directory, manually add the non-global zone root directory to the path that you want to protect. In this case, you cannot use auto discovery for the applications such as Oracle.
