Re: Isilon - Which node(s) are the master nodes?

There is no such thing as a "master node".  The only master/slave concept that really is applicable is which node is currently answering SmartConnect (DNS) Requests.  That node will always be the node with the lowest NodeID (not the lowest LNN) in a cluster that has an interface assigned in the correct subnet.  To understand the relationship between NodeID and LNN, run an "isi_config" -> "status advanced" -> "exit" the tables outputted will show you the LNN to nodeID relationship.
