Disk access

[GB Tek]

Is there a command to have a hot swap drive light to know it's path and physical location by disk access lights? We've had situations where we've had 8 drives and one reports bad, and I'm not sure which drive physically it is...

What kind of drives are you using? Is it in an array of some sort?

Maybe you can just run a dd on all the devices and the LED on the drive will light up (usually blinking green light), thus giving you the visual identification of a good drive. On the bad drive you would get IO error when you run dd.
# dd if=/dev/rdsk/cXtYdZ of=/dev/null bs=512k
