What: /sys/class/scsi_host/hostX/isci_id
Date: June 2011
Contact: Dave Jiang <>
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.
