 enclosure LEDs. The user must have root privileges to use these tools.
 .
 These tools use the SGPIO and SES-2 protocols to monitor and control LEDs.
 They been verified to work with Intel(R) storage controllers (i.e. the
 Intel(R) AHCI controller) and have not been tested with storage controllers of
 other vendors (especially SAS/SCSI controllers).
 .
 For backplane enclosures attached to ISCI controllers, support is limited to
