Method and apparatus for managing access to one of a plurality of raw storage devices in a computer system including a host computer and a storage system. The computer system includes a plurality of logical volumes of data that are visible to the host computer and the storage system and are perceived by the host computer as comprising a plurality of raw storage devices. The host computer includes a file system/LVM mapping layer. In accordance with one aspect of the invention, a request, from a requester having less than system administrator access privileges, to perform an action directly on the one of the plurality of raw storage devices is granted, so that a logical channel is provided to directly access the one of the plurality of raw storage devices without the logical channel being mapped by the file system/LVM mapping layer. Another aspect is directed to a computer system including a host computer comprising an application layer including at least one application program. A plurality of volumes of storage are visible to the application layer, and access privileges less than the root access privileges are assigned to the at least one application program to access the plurality of volumes of storage. |

DETAILED DESCRIPTION One illustrative embodiment of the invention is directed to a method of managing access to one of a plurality of raw storage devices in a computer system including a host computer and a storage system that is coupled to the host computer and that stores data accessed by the host computer, the computer system including a plurality of logical volumes of data that are visible to the host computer and the storage system and are perceived by the host computer as comprising the plurality of raw storage devices.
The method comprises a step of: (A) granting a request, from a requester having less than system administrator access privileges, to perform an action on the one of the plurality of raw storage devices.
Another illustrative embodiment of the invention is directed to a computer readable medium encoded with a program for execution on a host computer in a computer system including the host computer and a storage system that is coupled to the host computer and that stores data accessed by the host computer.
The computer system further includes a plurality of logical volumes of data that are visible to the host computer and the storage system and are perceived by the host computer as comprising a plurality of raw storage devices.
The program, when executed on the host computer, performs a method of managing access to one of the plurality of raw storage devices, the method comprising a step of: (A) granting a request, from a requester having less than system administrator access privileges, to perform an action on the one of the plurality of raw storage devices.
A further illustrative embodiment of the invention is directed to a host computer for use in a computer system including the host computer and a storage system that is coupled to the host computer and that stores data accessed by the host computer.
The computer system further includes a plurality of logical volumes of data that are visible to the host computer and the storage system and are perceived by the host computer as comprising a plurality of raw storage devices
