It could be the old driver/kernel module interface.
The one I have is /dev/sgx.
I have no /dev/cciss* present.

Besides, for HP Smart Array,
the example found in the documentation[1] uses a /dev/sg* path.

From the man page:


              To look at disks behind HP Smart Array controllers, use syntax such as:
              smartctl -a -d cciss,0 /dev/cciss/c0d0    (cciss driver under Linux)
              smartctl -a -d cciss,0 /dev/sg2    (hpsa or hpahcisr drivers under Linux)
