Convert pRDM to vRDM to vMDK
- First, make sure no one is accessing the pRDM. (pretty important, we are going to remove it from the VM)
- In the vSphere client, right click the virtual machine and select edit settings.
- Find the RDM you wish to remove, highlight it and select remove., then check “remove from virtual machine” and click OK.
- Allow the reconfiguration of the VM to complete.
- Then right click the VM and select edit settings. Click Add. Select hard disk and click next. Select Raw Device Mappings and click next
- Select the correct LUN and click Next. Click Next again. Select Virtual and click Next. Click Next again. Click Finish. Click OK.
- Allow the reconfiguration of the VM to complete.
- Now that the pRDM is a vRDM, you can svMotion it to a VMDK.
- Right click the VM and select Migrate. Select Change Datastore and click Next. Click Advanced.
- Find the RDM and click where it says browse. Select a Datastore and click OK. Now click where it says disk format and select Thick provision and click Next.
- Click Finish.
- The disk will now clone to a thick provisioned VMDK.
