I don't understand which questions 'yes' and 'yes' are the answers to.
If /dev/sda is a logical disk, rather than a physical disk, then yes, this
is the problem. In order to access SMART data on a disk, you need to be
able to address THAT physical disk. So if /dev/sda is a logical device
made up by both physical disks, addressed by the RAID controller, then
smartmontools won't work.
Howerver, your second 'yes' might be to say that /dev/sda is a single SCSI
disk. In this case, I would expect that you can access the SMART data, in
which case I am still confused about why smartmontools doesn't work
