Assuming the "Raid Subsystem controller board" presents a single SCSI
device to the host, you should be able to find it as /dev/sda. The first
partition on the device would be /dev/sda1.

If there is no partition on the device, you will have to use fdisk or
parted and other tools to partition it, format it and edit /etc/fstab to
automatically mount it. This looks to be a good tutorial on how to do all
of that:

YMMV and I have not followed the tutorial cited above, it just looked
reasonable at a quick glance through it.
