In JBOD mode controller exporting all devices to FS as normal disk devs, 
so megaraid IOCTL based API is not in use at all. It is great that LSI 
trying to deal with this, my requests were [silently] ignored. I would 
recommend them to look on the code, e.g. @ 
http://sourceforge.net/p/smartmontools/code/HEAD/tree/trunk/smartmontools/os_linux.cpp#l865 
. If they can provide a patch to get the SMART health status (or some 
reference code to do this) i would be happy to add patch to the product. 
But from my personal point of view problem is in the firmware SAT layer.
