kind of smartctl for RAID array?

Does anybody know how I can monitor disk self-test parameters of the
striped discs on a RAID controller?

Hardware: 3ware 7506-4LP (i.e., 4 port RAID controller with 4 ATA IDE
HDDs attached).

I would like to use something like smartctl, which is fine for /dev/hdX,
but apparently cannot cope with the RAID controller.

Anybody?

sorry for bothering the ng, RTFM action on myself reveals:
smartctl -a -d 3ware,DISKNUMBER
is my friend. Just overlooked it.

The problem with using something like smartctl with a RAID controller is
that the controller isolates the drives from the OS--you can only get SMART
out of it if the raid controller either provides that function or has some
way of passing low-level commands from the OS to the individual drives and
passing responses back.

Seems logical.
Anyway, the 3ware controller seems to pass all SMART interactions low
level to the discs, I get a full bunch of information regarding SMART
data for each attached HD. I am quite happy with it.
