Identify the Hardware Address of the SCSI card

This is the "ioscan -fC ctl" output on the environment show on the attached file

I Know that "0/3/1" refer to controler from the node, but I don`t undestand about 0.133.18.0.0.0.0 H/W path (SAN environment)

Could everyone tell me about it?
Why there are 4 H/W Path by controler?

# ioscan -fC ctl

Re: Identify the Hardware Address of the SCSI card

A FibreChannel hardware path is a complex thing. The meaning of the path components depends on the topology of FC connection (Fabric, Public Loop or Private Loop) and the used LUN addressing method. Depending on the equipment used, there may or may not be a way to easily map HW path numbers to FC switch ports.

Here's a good description of the whole thing:
