Most important is the complete "mdadm -E" output for every member device. With that you need a list that correlates the member device names to the underlying drive serial numbers. An *excerpt* from "ls -l /dev/disk/by-id/" would suffice. Or lsdrv output. I wrote lsdrv to generate a functional summary that includes all of the useful serial numbers.
