Node          Monitor                Subsystem         Alert ID
------------- ---------------------- ----------------- -----------------------
node-01       system-connect         SAS-connect       DualControllerNonHa_
                                                       Alert
                  Severity: Major
            Probable Cause: Configuration_error
Probable Cause Description: Disk shelf $(sschm_shelf_info.id) is connected to
                            two controllers
                            ($(sschm_shelf_info.connected-nodes)) that are
                            not an HA pair.
           Possible Effect: Access to disk shelf $(sschm_shelf_info.id) may
                            be lost with a single controller failure.
        Corrective Actions: 1. Halt all controllers that are connected to disk shelf $(sschm_shelf_info.id).
                            2. Connect disk shelf $(sschm_shelf_info.id) to both HA controllers following the rules in the Universal SAS and ACP Cabling Guide.
                            3. Reboot the halted controllers.
