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.
