The SiteAware attribute enables you to create sites to use in an initial failover decision in campus clusters. A service group can failover to another site even though a failover target is available within the same site. If the SiteAware attribute is set to 1, you cannot configure SystemZones. You can define site dependencies to restrict dependent applications to fail over within the same site. If the SiteAware attribute is configured and set to 2, then the service group will failover within the same site.

For example, in a campus cluster with two sites, siteA and siteB, you can define a site dependency among service groups in a three-tier application infrastructure. The infrastructure consists of Web, application, and database to restrict the service group failover within same site.
