Any update on this topic ?
I have the same card LSI 9260-8i and I confirm that the disk only shows in "Storage / ATA page"
In fact, this page seems to show the first disk of the array only
No way to find the disks on the other page, and no way to display the temparature in the OSD for example.
I also confirm that HD SENTINEL is able to report the SMART STATUS of every drive in the Raid arrays
