CentOS - Mar 2011 - OT LVM question

I've got a situation here where my LVM is showing the following problem:

Found duplicate PV xxxxxxxxxxxxxxxxxxxxxx: using /dev/sdb2 not /dev/sda2

Not sure what causes this and I really don't have a clue as to what the 
consequences are when seeing this  or how to fix it. Google just 
confuses me with any suggestions.

Can anyone offer any help, please?

What is the setup supposed to be? Have you altered lvm.conf in any way?
What does 'pvscan', 'vgscan' and 'lvscan' show? What, if
anything,
happened before this issue arose?

Were these drives once mirrored?
