HP proliant - Zenoss only sees internal disks

I have 4 X ProLiant BL685c G7 blades. Each one has 2 internal 300 GB drives, and then several fiber channel connected LUNS that reside on an EMC VNX 5500. I'm on Zenoss 3.2.1 (haven;t had the free time to check my zenpacks for an upgrade). I'm trying to monitor stats on the disks, and it only sees the 2 internal drives. They both show up individually under hard disks, and then the ingle logical RAID 1 shows up under logical disks. I do see the rest of the drives under File Systems, but that is it. Is there any way I can get graphs and data for the disks that actually reside on my EMC VNX?

Thanks,

Matthew
