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`

When doing lshw it is shown as

description: Fibre Channel
product: QLogic Corp.
vendor: QLogic Corp.
physical id: 0
bus info: pci@0000:04:00.0
version: 02
width: 64 bits
clock: 33MHz
capabilities: pm pciexpress vpd msix bus_master cap_list rom
configuration: driver=qla2xxx latency=0

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
