How the Resource Hosting Subsystem Plug-In Works

The CA ControlMinder installation process runs the Resource Hosting Subsystem plug-in during a CA ControlMinder installation, and the coexistence utility runs the Resource Hosting Subsystem when a customer executes the utility. The Resource Hosting Subsystem plug-in scans the computer for the Cluster Service Element, as follows:

1. Checks if the operating system is Windows Server 2008 or later.

   If the OS is of an earlier Windows version, the plug-in terminates.

2. Checks if the Cluster Service Element is installed on the computer.

   If the Cluster Service Element is not installed, the plug-in terminates.

3. Creates the following SPECIALPGM resource of type PBF:

   system_drive:\Windows\Cluster\rhs.exe
   

Note: The response file determines the default action that the coexistence utility performs at prescribed stages (what to do before CA ControlMinder installation, after CA ControlMinder installation, and so on).
