• 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.
