Oracle VM 3.1.1 Repositories in Dell MD3600f

Question

Hi Everyone,
I installed Oracle VM Server 3.1.1 on local disk on the server. I have external storage (Dell MD3600f) where is connected (Fibre Channel) to this server. In this storage I created 2 logical disk: 10GB to Server Pool and 1,1 TB to repositories.
I created server pool with this 10GB and works fine.
I have a problem with 1,1 TB because I cannot create data repository, I get folowing error:

I don`t know why is failed, what could be wrong??
Maybe it is bug in Oracle. I am a new one and this is my first installation.
Best regards

Answer 1

Why do you have the same UUID for the 10GB and the 1.1TB LUN?
The error is pretty straight forward. You shouldn't have the same UUID for each LUN.
