Or, to load the driver as a module at boot, place the following line in loader.conf(5):
isci_load="YES"
Hardware
The isci driver provides support for Intel C600 SAS controllers.
Configuration
To force legacy interrupts for all isci driver instances, set the following tunable value in loader.conf(5):
hw.isci.force_legacy_interrupts=1
Debugging
To enable debugging prints from the isci driver, set the
hw.isci.debug_level
variable to a value between 1 and 4 in loader.conf(5).
The hardware layer in the isci driver has extensive logging capabilities which are disabled by default for performance reasons. These can be enabled by adding
