If you can see activity lights, you can 'cat /dev/sd? >/dev/null' to make them busy, one at a time (where ? is a, b, c, etc).
hahaha, I've done that, only my version is...
# dd if=/dev/sdX of=/dev/null bs=512
but, same difference
It's unfortunately about the best we've got when device names are assigned more or less randomly. NICs are even worse - we need a command to make the lights blink there too.

Fully second that. The dd read test is the best way to tell which drive is starting to fail. As soon as one does it is not a bad idea to replace it.
Note that sometimes SMART drive and such technologies fail to detect missing sectors even when the dd test stumples upon them.
