A file translation system and a physical information and extensions file for an intermediary controller is disclosed. The file translation system that allow a host computer to directly access data from a different host type without moving the actual data. The physical information and extension file provides information concerning the location of data and the file system the host is viewing. The intermediary controller is disposed between a legacy disk controller for an originating host of a first type and an open system host. The intermediary controller emulates a virtual storage device using a virtual device file system, wherein the virtual device file system mapping data stored in a storage device by the originating host to objects in a root directory in the virtual device file system. The physical information and extension file comprising controller information for identifying the intermediary controller and logical device information, as well as any other information needed by an administrator or service technician.
An intermediary controller disposed between a legacy disk controller for an originating host of a first type and an open system host, the intermediary controller emulating a virtual storage device using a virtual device file system, the virtual device file system performing file system translation by mapping data stored in a storage device by the originating host to objects in a root directory in the virtual device file system to allow the open system host to locate and view the data of the storage device.
A physical information and extension file disposed in an intermediary controller located between a legacy disk controller and an open system host, the physical information and extension file translating data locations in a plurality of storage devices to a format readable by the open system host and indicating configuration data for the intermediary controller, the physical information and extension file comprising controller information for identifying the intermediary controller and logical device information.
A method of emulating a virtual disk by an intermediary disk controller disposed between an open system host and a legacy disk controller accessed by an originating host for storing data on legacy storage devices, comprising:
An article of manufacture for a intermediary controller, the article of manufacture comprising a computer readable medium having instructions for causing the intermediary controller disposed between an open system host and a legacy disk controller to emulate a virtual disk, the legacy disk controller being accessed by an originating host to store data on legacy storage devices, comprising:
