dsh is a distributed shell that basically runs the same command on
multiple servers. Notice that cass03 sees all 4 servers, yet the other
3 only sees three servers? Storage-conf.xml is the same among all
nodes i.e.
<Seeds>
<Seed>10.129.28.14</Seed>
<Seed>10.129.28.20</Seed>
<Seed>10.129.28.22</Seed>
<Seed>10.129.28.23</Seed>
</Seeds>
