The backplane may be expecting the host to control the LEDs. You'd have
to check with the manufacturer to be sure. As for how it would do this,
there's such a thing as enclosure management support in SATA, but the
sata_nv driver doesn't support it. If there is a way to use it on that
controller, only NVidia would know, since they've provided no
documentation for their pre-AHCI controllers. Some AHCI controllers do
have support for this..
