I agree with Simon, this has nothing to do with Xen or xe.

I am looking around but I can not find any samples to build al lvm stripe with

How to create local storage using a lvm stipe ?
Check LVM documentation. Essentially, that you probably want is to add the new disk, as a "physical volume" the your main "volume group". This will not give you a block level stripe, instead it will concatenate both storage spaces.

In order to get a block level stripe (or any other RAID technology), the common approach is to make LVM to reside over a RAID device instead of a physical disk. It might be hardware RAID, or software md device.
