Clustering a VPLEX virtual volume in MSCS

I've provisioned a virtual volume in VPlex and zoned it to two servers, one in each of our datacenters.

I'm unable to cluster the storage using Windows 2008 R2 Failover Clustering because the volume is being presented differently on each server.

On server one it is presented as EMC Invista and I can multi-path using Microsoft MPIO.  On server two it is presented as EMC LUNZ and I'm unable to multi-path and add it as clustered storage.

Any ideas why the volume is presented differently on each server?  Is there a different process that I need to follow to cluster the volume?

Thanks.
