Use Dynamic Multi-Pathing (DMP) to provide storage visibility in RHEV guest virtualized machines. DMP in the RHEV guest virtualized machine provides:
Multi-pathing functionality for the operating system devices configured in the guest
DMP metadevices (also known as DMP nodes) to represent all the device paths to the same physical LUN
Support for enclosure-based naming
Support for standard array types
For more information on DMP features, see the Dynamic Multi-Pathing Administrator's Guide.
