     260=== Node discovery === 
     261With xCAT, a node can be powered on and discovered automatically. Unlike the previous cases that nodes have to be known by the head node so that the head node can issue some ipmi commands to boot/install a compute node, in this case, the node can be rather unknown to the head node. However, some configurations are needed to make this work. 
     262 1. give the node an ip address in /etc/hosts, so it can be resolved. 
     263 1. make sure there is an available ip address in dynamic range of networks table for this node. This is going to be offered to the node via dhcpd.  
     264 1. make sure the node exists in nodelist 
     265 1. make sure switch table is correct for this node (i.e., switch.switch, switch.port) 
     266 1. makedhcp -n 
     267 1. power on the node and use tail -f /var/log/messages to monitor the procedure, then you should be able to ssh to the node when it's done.
