Abstract
A method and apparatus for reinitializing firmware in the event of a fault in a storage area network comprising at least one storage controller having programmable memory and RAM, said at least one storage controller for controlling data access between at least one host server and a storage device. The method is provided during background operations, and includes detecting a fault and suspending data access commands from the at least one host server. The firmware stored in programmable memory is reinstalled, and the at least one storage controller is reinitialized. The reinstallation of the firmware and reinitializing of the controller is quickly completed such that data access commands from the at least one host server to the at least one storage device are satisfied prior to the host server timing out and initiation a data access error message.
