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. | ||
