If they are unique LUNs being presented to the host through a single HBA and one FC switch or direct attach, then you will see two. If you have zoned the HBAs through two switches then double the count each unique LUN. What is the multipath issue you have?

Hi,
I have two FC switch, but i only see two lun.

In my /dev have two lun: sdc, sdd. After i setup multipath, i see mpath2(sdc), mpath3(sdd). I think it's wrong. But i don't know what i wrong.
I'm beginer.
Thanks.
