Convert your physical RDM (rdmp) to a virtual RDM (rdmv)

So you have a raw disk mapping on your virtual machine in esxi  and you wanted to convert it from a rdmp to a rdmv.
Using the VMware client it is no problem.




Go  to edit settings and select the raw disk







Click on Manage Paths
Make sure you get the path name
Important!
Take a not of your pathid: look under the runtime name.









Click Close
Now remove the virtual machine and delete the files from disk
Why? Because you are not deleting the lun, you are actually deleting the pointer to the lun.
Ok then ok







Now add back the hard disk this time as a virtual RDM
Remember the path we jotted down? That is why you neede d to do so.
Back to edit
Add hard disk









Select raw device mapping







Select your lun
Check the PathID, that will help you if you having issues.
Compare it to your notes from before







Store with the vm





Choose virtual














Click Finish
Then ok











You just changed your RDM from a physical RDM (rdmp) to a virtual rdm (rdmv)
