It might be nice for someone to write a fencing agent that would talk to
the iscsi target software.  Until then you can use network power switches
or manual fencing to experiment.

This is because the fence daemon (fenced) is either not running or has not
started up correctly (maybe it can't connect to ccsd).  You can diagnose
fenced problems by using the debug flag: "fenced -D".
