Virtual mode RDM data can be migrated to a VMDK disk with Storage vMotion by selecting the Disk Format from Advance View. The same host retains ownership or registration of the virtual machine after Storage vMotion completes. When you perform Storage vMotion, the virtual machine files are physically relocated to a destination datastore. We can convert virtual compatibility RDM disks to VMDK disks during Storage vMotion to different datatsore. Virtual compatibility RDM disks allow RDM to act exactly like a virtual disk file, including the use of snapshots. How to Convert RDM to VMDK Convert Virtual RDM to VMDK using Storage vMotion We need to understand how to convert RDM to VMDK and this article will explain you the detailed procedure to convert both virtual and physical RDM disks to VMDK. Instances such as migrating VM across datacenter without having the option to move with RDM disks, Decommission of storage array where RDM LUN is allocated, etc. There could be various instances that we may need to convert RDM to VMDK. Take a look at the 11 differences between RDM physical vs virtual Compatibility Mode. There are two types of RDM Disks ( Virtual Compatibility RDM and Physical Compatibility RDM). Diff VCenter 5.5 appliance and vCenter on WIndowsĪs we already discussed many times, VMware RDM (Raw device mapping) is a mapping file that provides direct access to a LUN on the fiber channel storage system for a virtual machine.
