[smartmontools-support] How do I enable smartctl on 3ware controller - drive?

[a***@gmail.com]

Hi, I'm trying to figure out the syntax to enable smartctl on drives behind
a 3ware raid controller. I've tried many combinations from the man pages
but none seem to work. Here is the hardware and what I have tried. Thanks!
