Drives in Disk Manager show up as Unknown and Unallocated when connecting to SAN via iSCSI

Here is our setup:

HP BL365 G7 running Windows 2008 R2 SP1 connected to two sans:

1. EMC CX4 via Fiber

2. EMC VNX5300 via iSCSI

We currently have 4 servers in a Hyper-V failover cluster. We are migrating from our older CX4 to a newer VNX5300. The four servers are successfully connected to both and migrations between the two SANs works fine. We need to add a 5th server to the cluster. We did a new installation of 2008 R2 SP1 on our blade and connected it via Fiber to the CX4 and iSCSI to the VNX5300.

All of the drives on the CX4 show up properly: they are "offline" but show they have a simple volume on them (they are blue). This means that it can see the partition on them but they are offline because the drives are part of a failover cluster and this server doesn't own any of the drives.

All of the drives on the VNX5300 show up but not properly: they are all "unknown," "offline," and they show up as "unallocated."  The server doesn't recognize any of the volumes on them and if you were to try to bring them "online," you get an error saying, "The device is not ready." 

All machines have EMC Powerpath installed on them for Multipath management and have the Navisphere agent installed.

We have set these machines up in the same manner and this is the second machine that is giving me this issue (I ruled out hardware issues by getting a second blade and trying it again).  I'm sure there is a configuration setting somewhere that I'm missing, but at this point I'm stuck. 

Any help is greatly appreciated,

Jeff
