Issue



Backup of a Virtual Machine fails with - Unable to open a disk of the virtual machine - The virtual machine has physical disk(s). The disk marked physical RDM will not be backed up.

Unable to backup a VMDK (Virtual Machine Disk Format ) that exists on a RDM (Raw Device Mapping) in physical compatibility mode.


Error



Completed status: Failed
Final error: 0xe0009585 - Unable to open a disk of the virtual machine.
Final error category: Resource Errors

The virtual machine has physical disk(s). The disk marked physical RDM will not be backed up.
 


Solution



To protect Virtual Compatibility-mode or Physical independent-mode RDM disks, Symantec recommends to install a Backup Exec Agent for Windows Systems or Agent for Linux inside of the Guest virtual machine and protect them as if they were physical systems. 
 
Virtual compatibility mode RDM disks can be backed up but cannot be directly restored by Backup Exec to an ESX server or existing Guest virtual machine.
Virtual compatibility mode RDM disks are included in the backup of the selected virtual machine automatically and will include ALL data located on the mapped LUN.
 
Neither physical nor virtual compatibility mode disks can be used with the Incremental or Differential backup capabilities. A Guest virtual machine configured with RDM disks will result in the entire virtual machine being unable to use Incremental or Differential backup settings
