Creating and Using Scenarios › Use Scenario Groups › Create a Scenario Group

Create a Scenario Group

There are two ways to create a scenario group:

• During the creation of a new scenario, through the Scenario Creation Wizard.
• Before the scenario creation, through the New Group option, as described below.

Note: We recommend planning and creating the scenario groups you want to use in advance. After you assign a scenario to a certain group, you cannot move it to another group.

To create a new scenario group

1. From the Manager, click Scenario, New Group from the menu, or click the New group button on the Standard toolbar.

   A New group folder is added to the Scenario pane.

2. You can change the group's name by right-clicking it and selecting Rename from the pop-up menu, or by double-clicking the current name and entering a new name.

   The new group name appears on the following places: the Scenario pane, the Group drop-down list in the Scenario Creation Wizard, and the Overview Page.

   Note: When no scenario is defined, empty scenario groups do not appear on the Overview Page.

Set Group Properties

Configure the group properties on the Arcserve RHA Manager Properties tab.

The group properties include:

Scenario Dependencies

Manages the interdependencies between scenarios. Usually a distributed application has multiple components/roles/servers which are interdependent. Any scenario can be configured to depend on one or more scenarios or multiple scenarios can depend on a single scenario. These services can be handled by the Scenario Dependencies property.

Switchover Settings

Manages the switchover setting in a distributed group. Some of the switchover setting options include:

• Switchover as a Group: If this option is set to On, the whole group (all the scenarios) will be automatically switched over together in case one of the scenarios is failed and ready to take switchover.
• Failure Triggers Group Switchover: A single failure can trigger a group switchover. By default, all scenarios can trigger group switchover, and you can configure some light-weight scenarios to be set to Off.
• Execute Scenario Switchover Settings: This option decides whether the scenario should execute its own switchover settings.

Scenario Availability Sets

A distributed application might configure two or more servers to provide same services to improve availability or performance. When one server is down, the other servers are still working and can still provide the services. Scenario Availability Set will be used when Arcserve RHA manages these servers/scenarios of that distributed application.

If two scenarios are configured in the same Scenario Availability Set, the group switchover is initiated only when both scenarios fail. This function is not invoked when one of the options fail.

Note: The same group can have one or more Scenario Availability Sets, but one scenario cannot be configured in two different sets.
