Hi Ian,

I've had this happen again.  When I run the ruby script it shows the 
host which is unavailable and also shows all the unreachable VMs (some 
of the output is below).  How do I get the GUI to recognise the node is 
there so I can manage things again (without restarting)?  I'd rather not 
have to restart everything as then I have to deal with the iSCSI 
wierdness which is going on.

Is there anything else you'd like me to check while it's in this state?

Cheers,
Justin.
