When creating Control Service scenarios, Assured Recovery is not supported and the option is unavailable.
- Open the Arcserve RHA Manager. Then, select from the Scenario menu the New option, or click the New button on the Standard toolbar.
The Scenario Creation Wizard opens.
- Select the required scenario options, as follows:
- Select the Create a New Scenario option button.
- From the Group drop-down list, select the group to which you want to assign the new scenario, or enter a name for a new scenario group.
- Click Next. The Select Server and Product Type page opens.
A list of available applications and scenario types is presented.
Note: The list of available applications depends on the licenses applied.
Select the required scenario options, as follows:
- From the Select Server Type list, select Control Service.
- From the Select Product Type options, select High Availability Scenario (HA).
- Note that Integrity Testing for Assured Recovery is not supported for Control Service HA scenarios.
- Click Next. The Master and Replica Hosts page opens.
- Enter the following information:
- In the Scenario Name box - accept the default name or enter a new name for the scenario. When entering a name, choose a unique name, since you cannot use the same name for more than one scenario.
- In the Master Hostname/IP box - the system automatically enters the hostname or IP address of the (active) Master Control Service, based on the Control Service details you entered for opening the Overview Page. These details cannot be changed here. To use a different Control Service, you need to connect it to the Overview Page, and then reopen the Manager.
- In the Replica Hostname/IP box - enter the hostname or IP address of the Replica (standby) Control Service, or use the Browse buttons to find it.
- In the Port boxes - accept the default port no. (25000) or enter a new port numbers for the Master and Replica.
Notes:
- The Assessment Mode option is disabled in HA scenario.
- The Verify Arcserve RHA Engine on Hosts check box - select this check box if you want the system to verify whether Engines are installed and running on the Master and Replica hosts you specified in this page. If Engines are not installed on the selected hosts, you can use this option to remotely install the Engines on one or both hosts. For more information about the Host Verification page, see Creating a Scenario.
- After you selected the desired options, click Next. The Master Configuration page opens.
Arcserve RHA auto-discovery component automatically displays the directories and files that are on the active Control Service. These directories and files are the data that will be replicated and protected.
The replicated Control Service items include:
- Product Registration - product registry keys
- Scenarios - xmc files of scenario definitions
- Templates - xmc files of user-defined templates
- Reports - files of scenario reports
- Configuration and Management files
Note: In HA Control Service scenarios, you cannot exclude Control Service items from replication. In Control Service Replication scenarios, you can exclude the items you do not want to replicate, by clearing their check boxes.
- Click Next. The Scenario Properties page opens.
The Scenario Properties page enables you to configure the scenario properties that affect the entire scenario. Typically, the default values are sufficient.
If you want to configure the scenario properties at this stage, refer to Understanding Scenario Properties. To configure the scenario properties at a later stage, refer to Configuring Scenario Properties.
- Click Next. The Master and Replica Properties page opens.
The Master and Replica Properties page enables you to configure the properties that are related to either the Master or Replica host. Typically, the default values are sufficient.
If you want to configure the Master and Replica properties at this stage, refer to Setting Master and Replica Properties. To configure the Master and Replica properties at a later stage, refer to Configuring Master or Replica Server Properties.
Note: You can modify all the settings in this pane after the scenario is created. However, before changing any Spool properties (which can be configured here), review the Spool information for configuration details.
- Once you are satisfied with the Master and Replica properties, click Next.
The Switchover Properties page opens.
The Switchover Properties page allows you to modify switchover parameters. As with the prior steps, no changes are required.
If you want to configure the switchover properties at this stage, refer to Understanding High Availability Properties. To configure the switchover properties at a later stage, refer to Configuring High Availability Properties.
Notes:
- When selecting the Network Traffic Redirection method, there are only two methods you can use for this scenario: Redirect DNS and Switch Computer Name. You cannot use the Move IP redirection method.
- The Is Alive Timeout (sec) property controls how long to wait after a failure is detected before triggering an automatic switchover. The default is 300 seconds. For more details, review the Is Alive information.
- Click Next. A notification message appears informing you that Arcserve HA verifies the validity of the new scenario and checks many different parameters between the Master and Replica servers to ensure a successful switchover.
Note: In HA Control Service scenario, once a Master failure is detected, a switchover and a backward scenario are always initiated automatically. You cannot disable this automatic initiation. However, you can also manually initiate a switchover, by clicking the Perform Switchover button.
- Once the verification is completed the Scenario Verification page opens.
- If the scenario was not set up correctly, or problems occurred in the participating hosts or the connection between the Arcserve RHA components, the errors and warnings detected are displayed, and two additional buttons appear: Retry and More Info.
- To repeat the verification process, click the Retry button.
- To view additional information about the errors and warnings, click the More Info button.
The Verification Results dialog opens, listing all the errors and warnings detected.
The Verification Results dialog provides you with detailed information about the checks performed to help diagnose problems. It is intended to help you resolve any issues encountered in running the software. You can also contact Technical Support for further assistance.
- If any errors are displayed, you cannot run the scenario. These errors must be corrected before you can start the synchronization, replication and HA processes.
- If only warnings are displayed, you can run the scenario. However, it is important that you consider the warning carefully since they indicate conditions that are known to potentially cause problems with replication or switchover. To close the dialog and return to the Scenario Verification page, click the Cancel button.
- When the scenario is verified successfully, on the Scenario Verification page click Next to continue.
The Scenario Run page opens.
- The scenario configuration is now completed and you are prompted to run it. Running the scenario starts the data synchronization process, following by replication and is alive checks.
- To finish the scenario creation and run it later, select Finish.
- To run the scenario, click Run Now.
- The synchronization process starts. Synchronization may take a while depending on data size and network bandwidth between the Master and Replica. You will receive the following message in the Event pane when synchronization is complete: All modifications during synchronization period are replicated.
From this point, real-time replication occurs and the High Availability solution is active.
