The function 'scic_sgpio_hardware_initialize' is called in the fi= le 'sys/dev/isci/scil/scic_sds_controller.c'. Although there is no call to = 'scic_sgpio_set_led_state' or 'scic_sgpio_update_led_state' in the whole so= urces (/usr/src). > > Can somebody give me a hint how to manipulate the LED's? There's no way to manipulate the LEDs on the system as you have it. LED support is not in the current isci driver. But can you try this patch? http://people.freebsd.org/~jimharris/isci_led.patch The LEDs will show up as /dev/led/isci.busX.portY. On C60x SKUs with 8 isci ports (which I think yours has), the isci driver will create 2 buses of 4 ports each (to match the underlying silicon implementation), hence the need to use bus and port numbers in the name, rather than just port.
