But if there are several VMDK (or RDM) disks of the same size or several virtual SCSI controllers are there in a VM we will need to match the Windows disk to avoid errors. I will upgrade the imaging system to the latest version running 64bit.
RDM gives you the advantages of direct access to disks while keeping some advantages of a virtual disk in the VMFS file system. The VMDK file format competes with the Microsoft Virtual Hard Disk (VHD) format used with Virtual Server and Hyper-V hypervisors. The second option is the use of Raw Disk Mappings (RDM) to directly present physical volumes or disks to the VSA VM.
5 update 2 and for vStorage, the RDM is ignored (not backed up) and any independent disk is recreated but empty. Tick "Force BIOS Setup" (This will boot into the BIOS screen when the VM is powered on - This is so that you can mount and ISO image before the OS boots. This script will connect to the vCenter (or ESXi) server and get the list of disks for the specified VM.20GB virtual disk (vmdk) for VMFS and VMFS MP tests 20GB LUN for MS iSCSI, MS iSCSI MP, RDM physical and RDM virtual tests MS iSCSI initiator used virtual machine’s VNXNET 3 adapter (one or two depending on the configuration) that was connected to the dedicated iSCSI network through ESXi’s 10GB nic.RDM is a mapping file and is used to map a LUN directly to VM bypassing VMFS layer.
