An afs-volume lives only in one afs-partition. (Although you can have
copies of that volume on other servers.)
An afs-partition is identical to a filesystem-partition of your OS.
Afs-Partitions cannot span multiple os-partitions or even servers.

With your hardware-configuration, you need to merge all 4 partitions
into one.

On the servers it might be easy (either with your HW-Raids themselves or
with LVM on Server-Side). Be aware that there needs to be a special
compile-time option enabled to support blockdevices larger 2TB.

To merge the partitions accross servers, you could think about
software-iSCSI or the good old network-block-device.

You did not tell us why you need one 4 TB volume. Perhaps you should
think about your volume-policy or consider an other filesystem.
