Hyper-v connected to CX3-40f LUNs

Hi,

I am trying to use CX3-40f as an external storage connected with two servers PE-2950 with Windows 2008 Hyper-V enable.

I am using Sql on VM running on Hyper-V.

I created Raid, Storage group and presented the LUNs to these two servers.

I am able to see these LUNs  in disk management, buts not all at the same time...i even restarted the the machine but wasn't successfull, it gets sort of hang some time...

If I remove these LUNs ..it works fine,

By the way i didn't initilized those disk on the physical servers.

Model of the storage: CX3-40f

Flare Version: 03.24.040.5.011.

Sorry for sure a lengthy question...would really appreciate for your kind support
