Raw Device Mapping (RDM) Disks

To create an RDM disk using CreateVM_Task, use a LUN that is not occupied and thus is still available. Developers sometimes use the same LUN uuid that is available in the configInfo object, which can cause errors because the LUN uuid is datastore specific.

Call QueryConfigTarget to fetch the ConfigTarget.ScsiDisk.Disk.CanonicalName property, set in VirtualDiskRawDiskMappingVer1BackInfo.deviceName. Also call QueryConfigTarget to fetch ConfigTarget.ScsiDisk.Disk.uuid, set in VirtualDiskRawDiskMappingVer1BackInfo.lunUuid. When creating the virtual machine, avoid host-specific properties of configInfo, which should be set according to host configuration where the virtual machine is restored.
