   4 Description:
   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.
