I've installed the Intel x520-sr2 Ethernet/Fibre card into a server that has Oracle Linux 6.2 Installed on it. When I boot the server I can go into a QLogic menu (screen has something for Intel on copyrights so I believe this is the correct card but combined with QLogic Technology). In the menu the two ports show up and I can see their MAC addresses.

Using Oracle Linux 6.2 (Basically Redhat 6.2), I need to setup multipath over a fibre network. I'm using a Dell Fibre Switch and can see the connections are plugged in and active from its GUI. I need to find the WWN or IQN number for my storage device to setup the Initiator to grant access. Not sure where to find that info on Oracle Linux?

Can I use SANsurfer or something like that to see the LUNs and connections?

After seeing the connections do I just install the multipath modules and it will find the paths, or is there more to do?

Have you read RedHat's Multipath manual?… If you go step by step there you'll be able to setup a proper, resilient multipath system. – Mxx Jan 24 '13 at 17:31

Installing multipathd, and running multipath -v ; multipath -ll; should be sufficient to see what multipath devices you have. You can then add these to the /etc/multipathd.conf file to give them persistent names where needed.

I mostly use iscsi these days, but from what I can remember from my FC-days... powerpath, or sansurfer should give you your Lun information. – Sig-IO Jan 24 '13 at 16:48
