if you have presented any specific storage disk to only specific nodes, then all nodes will not have storage installed

You need to present new disks to all nodes or need to remove unwanted disks from failover cluster because 2012 and above failover cluster by default try to add all available disks to cluster except system/boot/page dive

[edit: I misread your question. I thought you needed to expand storage. Sounds like you are doing initial installation]
Did you expand the LUN(s) on the MD3800?

Once the LUNs are expanded, use diskpart.exe on the VM that hold the active failover role to expand the partition. syntax goes a bit like this.

diskpart.exe
rescan
list disk
select disk x
list part
select part y (usually 1 for MBR disks and 2 for GPT disks)
extend
list disk (should show no free space on the disk now)
exit
