Hi Tim,  If you are referring to the nodes automatically powering themselves up after a loss of power, then I believe the answer is no.  You have to manually power up each node.  But that being said, as the nodes power up, the cluster will start automatically; each node should come back up and rejoin the cluster assuming there are no severe problems.  Cheers, Matt
Does an Isilon Cluster start automatically when recovering of a site power loss or do you have to start the cluster manually?  Regards, Tim
