Multipathing Configuration.

Hi All,

I have a Dell Server where I did connect a storage back to back. And presented six 597G Luns. and configured Multipathing. Not sure if this set up right. And when I do run this command I do get this output.
fdisk -l| grep Disk\ \/dev

And when I do multipath -ll command I do see this.

multipath -ll

My question is:
Is it ok that I'm seeing /dev/sd* disk when I'm running fdisk command or it mean that I do configure multipathing wrongly?
