+What: /sys/class/scsi_host/hostX/isci_id
+Date: June 2011
+Contact: Dave Jiang <dave.jiang@intel.com>
+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.
