Script to save array info

[Wakko Warner <wakko@xxxxxxxxxxxx>]

After reading some of the stories about lost metadata, I was wondering if
anyone had a script that would output the member info for each device with
the device's physical serial number.

For a crude one I did this while in /sys/block:
for x in sd*;do
	echo /dev/$x
	/lib/udev/scsi_id --export --page=0x80 --whitelisted /dev/$x
	mdadm -E /dev/$x
done

And saved the output.  It works for me because all but 3 of my raid members
are full disks.
