+Description:
+                This file contains the enumerated host ID for the Intel
+                SCU controller. The Intel(R) C600 Series Chipset SATA/SAS
+                Storage Control Unit embeds up to two 4-port controllers in
+                a single PCI device.  The controllers are enumerated in order
+                which usually means the lowest number scsi_host corresponds
+                with the first controller, but this association is not
+                guaranteed.  The 'isci_id' attribute unambiguously identifies
+                the controller index: '0' for the first controller,
+                '1' for the second.

+Description:    Display minimum, maximum and current range of the steering
+                wheel. Writing a value within min and max boundaries sets the
+                range of the wheel.
