How to give a SAN stoarge in shared across the cluster using Fiber channel

In RAC environment storage should be in shared which means that all node in the cluster should be able to access the same storage array.

If we are using fiber channel method to connect from host to SAN storage. For each host there will be one unique WWN (World Wide Number) by giving this WWN to the LUN's which are mapped to the hosts in the cluster, then all the nodes in the cluster will be able to see those LUN's.
