If you want to actually nuke/erase the component labels, then 'dd' does the
job. If what you really want to do is just update the component labels to
reflect the 'raidctl -C' configuration, then a 'raidctl -I 12345' will do
the trick. (I probably should have suggested 'raidctl -I' in addition to
the 'dd' in my previous message... but there are times when you actually
need to completely remove a component label.)
