I have just compiled the QLogic qla2xxx FC driver on a CentOS6.4 host, and done

echo 'alias scsi_hostadapter qla2xxx' >> /etc/modprobe.d/modprobe.conf

cd /boot
cp initramfs-$(uname -r).img initramfs-$(uname -r).img.bak
mkinitrd -f initramfs-$(uname -r).img `uname -r`
reboot

When doing lshw it is shown as

description: Fibre Channel

Question

How can I figure out which device the driver created in dev?

There won't be a device entry until actual disks are connected. After that, you can see those with lsscsi, which you might need to install first.

In my case a NetApp is connected at the other end of the FC cable. Can I somehow force(?) the device to be created, so I can enter the device name into a config file? –  Sandra Oct 3 '13 at 13:32
