Prepearing for testing

The cluster is ready to use.
Now I need to add my "HA-cluster-Storage" as a storage for my virtual machines:

Go to "Datacenter"-"Storage"-""Add" - iSCSITarget

Fill

 ID:NAS01-PVELUNS
 Portal : 172.16.70.2
 Target: iqn.2012-03.nas01:iscsi.PVELUNS
 Uncheck "Use LUNs directly"

And then, "Add" - LVM group

Fill

 ID:NAS01-LUN1

 Base storage: NAS01-PVELUNS 

 Base volume: CH 00 ID 0 LUN 1

 Volume group: NAS01LUN1VG0

 Check "Shared"

Ok, now we can see:

Now lookup to node1:

What does  "Found duplicate PV MiXXJdMcRElPXQPEtzc6pPFAQLhQn0lC: using /dev/sde not /dev/sdd" mean? And why this appear?

I will thinking about it...
