the fact that you are seeing LUNZ is not normal, do you not have any LUNs at host id 0 ?
We have a windows 2008 sp1 host that is part of an Exchange 2010 DAG.  The Clariion luns are presented to the host and in device manager the local disks show as disk 0 and 1, and you would normally expect to see the clariion luns show up as disks 2 - 12, but in this case it skips 2- 6 and pick up at disk 7-16.  Device managers show the disks 2- 6 as unknown.  They are the DGC LUNZ devices.  What can I do to have the actual luns presented i nthe expected order.  Do I just unpresent the luns run a powermt check and then represent the luns.?  Any help or guidance would be greatly appreciated.

Clariion devices in W2008 skip over disk 2-6 pick up at 7
