Embodiments of the present invention provide a system and method of command tracking that eliminates, or at least substantially reduces, the shortcomings of prior art systems and methods for command tracking. More particularly, embodiments of the present invention provide a system and method in which a command is assigned a unique identification. State information for the command (e.g., has the command been completed, has all the data associated with the command been received and other state information) can be associated with the unique identification and recorded. According to one embodiment, the state information can be stored in various tables that correspond to particular data transport protocols and/or devices. Because the state information for the command is associated with the unique identification in the tables, state information for the same command can be identified, even if the command changes data transport protocols.
