san

How do I check if a LUN has been presented to my server ? What are the Linux commands for that ? Do the LUNS show up in a fdisk -l command like a normal /dev/sda gets listed ?

What are other commands assosicaed with general SAN related checks in Linux ? What is WWN and how does that have any relevance and Also please explain multipathing why if we have LUN's , what is the use of multipathing then ?

Bit lenghty but I am not able to get a grasp on the topic . Any help would be appreciated .
