| 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. |
