CentOS - Nov 2012 - Raid 5 Q

I have a raid 5 built on an opensuse box that I just reinstalled Centos 
6.3 on.  Is it possible to rebuild the raid 5 array non-destructively?

I have googled on this and have found using mdadm --scan --assemble 
<list of fd devices>.  Will this do it?  I sure wouldn't want to lose
my
data on the array if possible.

thank you,

Phil

It could be possible, but I think I would rather try to back it up with some
sort of recovery system first... If the data is VERY critical, I would clone
the drives with DD first just to make sure...
