"Found duplicate PV bla-bla-bla" problem

[eugenyh]

Cannot resolve by myself.

Have a PM2.0 cluster (4 nodes).
Added iSCSI storage. All process described on
my blog (http://eugenyho.blogspot.com/2012/04/prepearing-for-testing.html) There is no complication.

But,

pvdisplay ​

show me message:
Found duplicate PV MiXXJdMcRElPXQPEtzc6pPFAQLhQn0lC: using /dev/sde not /dev/sdd

Any Idea?
