Managing Replication and High Availability Scenarios › Group Properties

Group Properties

You can configure the group properties using the Scenario Creation Wizard, while creating a scenario.

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.

If there are Load-Balancing WFE servers configured in the SharePoint farm, it is recommended that you configure the scenarios protecting WFE servers to be in same scenario availability set.

Event Notification

Lets you configure the policies for the group event. Some of the policies include:

• Notify by email: Send an email to specified recipients.
• Execute script: Execute some pre-defined script.
• Write system event log: Write a log to Windows system events.
