Infrastructure Software

Hi all,
I'm new to storage matter, so maybe I'm doing a silly question.
I'm trying to configure multipath on an external storage from OEL 6.

I know that two FC connections have been made between my Server and the external storage.
I expected to see two external drives on my Linux Server, both pointing to a single physical disk.
But if I check with "fdisk -l" I see a single external disk:


[root@host ~]# fdisk -l

La partizione 1 non termina al limite del cilindro.

SDA is my internal disk, SDB is the external disk. I expected to see even something like SDC, pointing to the same external disk as SDB.
Have I done something wrong?

Thank you,
Gianluca
