Installing on FC volume

[MasterG]

I would like to install my system (Windows 2008 Server) on a FIbre Channel volume. I have 4 FibreChannel adapters (2x Qlogic 2340, 2x Qlogic 2310) with which I have been doing the tests. Now, there's no problem installing the system on an FC volume with 512 byte blocksize, but when I set up a 4 kB volume, the volume shows up in the installer and it's possible to create a partition, but it's not possible to format the volume with NTFS (the system freezes at that exact moment). The configuration is exactly the same as when trying the 512 byte blocksize. Anybody had the same problem? It doesn't seem to be connected to FC itself.. Any tips? Thanks in advance!
