Linking Intel RAID 5 partitions to boot disk

I have a 5-disk Intel RAID 5 along with a 6th boot disk with /, /boot, and swap. What I was planning to do was mount the Intel RAID partitions (which I've added with fdisk) so that the 6th disk /home, /var, /srv, etc. link to the RAID on the other 5 disks. So far, my attempts at doing this have failed (editing fstab, trying to mount the /dev/dm-* partitions manually, etc.) have failed. Does anyone have experience in this and can point me in the right direction? Edit: I have the RAID array partitioned so that I can mount each partition as a folder on the boot disk, i.e. RAID /dev/dm-0 -> bootdisk /home.
