We want to make a PTV where the physical machine, have a mounted Lun.
The Virtuel machine will then have the same name and IP.
The way to do so, is that to add the storage to the Virtuel machine as Raw device mapping?
Or would that be wrong, if so what would be the rigtht way?

There are a couple of issues that will drive the decision whether to keep it as a raw device mapping, or to convert to a VMDK.

The first is whether your datastore has the capacity and performance to meet the requirements of the application.  If so, there are few reasons to use a raw device mapping, and several reasons to switch to a virtual disk.

The reasons to convert to a virtual disk are a) standardization (all VMs behave the same way), b) reduction of complexity, and c) backup/recovery/replication.  If you're using a product like Veeam or vSphere replication, then using VMDKs is very desirable.
