1What: /sys/class/scsi_host/hostX/isci_id 2Date: June 2011 3Contact: Dave Jiang <dave.jiang@intel.com> 4Description: 5 This file contains the enumerated host ID for the Intel 6 SCU controller. The Intel(R) C600 Series Chipset SATA/SAS 7 Storage Control Unit embeds up to two 4-port controllers in 8 a single PCI device. The controllers are enumerated in order 9 which usually means the lowest number scsi_host corresponds 10 with the first controller, but this association is not 11 guaranteed. The 'isci_id' attribute unambiguously identifies 12 the controller index: '0' for the first controller, 13 '1' for the second. 14
