Hi neil:
In mailist, many people ask the question about disk order.
But because the reboot or anthor probelm, the disk-name maybe change.
So we can't get disk-order.But if we can add WWN(Now,most harddisk has this attribute),
we can find the orders anything.
Thanks!

What exactly do you propose doing with a WWN - how would you use it.
The metadata already contains enough information to determine the correct
disk order.
