1. A method for providing multiple media agents with shared access over a fibre channel small computer system interface (SCSI) interface to a storage device in a computer network, comprising:

  • in response to inquiry messages on SCSI interfaces to the storage device in the computer network, providing a shared operational mode on the SCSI interfaces for a first media agent configured to perform a first data storage operation with the storage device and a second media agent configured to perform a second data storage operation with the storage device,wherein the storage device appears as a SCSI target device to the first media agent and the second media agent via an access media agent, located at a storage area network (SAN) server, that is configured to arbitrate access to the storage device by the first media agent and the second media agent configured to control the SAN sever to appear as a SCSI target to both the first media agent and the second media agent, andwherein the first media agent and the second media agent are configured to perform data storage operations associated with the storage device for one or more client devices; and

    mapping, via the access media agent, data storage operations between the first media agent and the storage device and data storage operations between the second media agent and the storage device, via the controlled SAN server, to logically unique channel numbers for the first media agent and the second media agent, to perform data storage operations over their respective SCSI interfaces by concurrently sharing the storage device.
