Abstract
Method and apparatus for accessing a block data storage device through a computer network to carry out remote diagnostic operations. The data storage device includes a data storage medium, a host interface port, a serial communication (COM) port and a programmable controller with associated platform firmware and associated diagnostic firmware. A client computer and a server computer are connected to a computer network, and the data storage device is connected to the server computer via the host interface port. The server computer is used to transmit a first command to cause the controller to execute the platform firmware, while the client computer is used to transmit a second command to the COM port of the data storage device to cause the controller to concurrently execute the diagnostic firmware to monitor operation of the platform firmware.
