If you have direct knowledge, which serial number is where, you could use hdparm -I /dev/sdX or smartctl -a /dev/sdX against the still reachable drives. Possibly the easiest is to *read* data from the still reachable disks and check which LED does not blink anymore - if you have LEDs for each of the drives (dd if=/dev/sdX of=/dev/null). Otherwise someone needs to look at the "open" hardware to find the serial numbers. Does this help? cheers Carsten -- To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
