Use globbing and parameter expansion to get the raid slave devices
Uses bash globbing and parameter expansion to find all of the slaves for
a raid device. This is a much better method then using ls. Also, by
looking at DEVNAME in the uevent file we provide support for block
device that are not in the root of /dev.
