Install the array configuration utility and verify if you can see the disks using this tool.

Sometimes, a reboot is needed to detect disks if a rescan of the scsi bus does not do the job.

It seems that the system is detecting only the internal controller with 3 disks. And the device that you currently see in the fdisk -l output is an array of the internal controller.

You should check your hardware connections.
