The SIOS Protection Suite Extend Resource Hierarchy option copies an existing hierarchy from one server and creates a similar hierarchy on another SIOS Protection Suite server. Once a hierarchy is extended to other servers, cascading failover is available for that resource. The server where the existing hierarchy currently resides is referred to as the template server. The server where the new extended hierarchy will be placed is referred to as the target server.

The target server must be capable of supporting the extended hierarchy and it must be able to communicate with equivalent hierarchies on other remote servers (via active SIOS Protection Suite communication paths). This means that all recovery kits associated with resources in the existing hierarchy must already be installed on the target server as well as every other server where the hierarchy currently resides.

  1. To extend an existing resource hierarchy, select that server hierarchy you want to extend and then select Extend Resource Hierarchy from the resource context menu or resource context toolbar.
  1. Select the Backup Server and click Next.
  1. A dialog will then display the results of SIOS Protection Suite’s pre-extend checks. If these tests succeed, SIOS Protection Suite will display a message stating that the pre-extend scripts were successful. Click Next to enter any remaining data needed for the specific type of resource hierarchy that you are extending.
