Display WWN in SLES 10

A key component of setting up a server to a SAN is knowing what the World Wide Name (WWN) is. I was very accustomed to doing this in SLES 9. With SLES 10, the location of finding the WWN has changed and it is now in the file /sys/class/fc_host/host#/node_name. Where # is the number of the host that you want to find the WWN of. 

An even easier way to find this information is to use the systool command:
systool -c fc_host -A node_name
