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.

AH for the days of HSZ70 boxes... There is a command to make a selected disk in the array blink its light...
