System and method for processing commands

Embodiments of the present invention provide for conversion between command protocols. A routing device, or other device in the command path, can receive a command from an initiator, determine if the initiator and target for the command support the same command protocol and, if not, convert the command and/or response between the command protocols used by the initiator and the target. For commands not supported by the target or for particular predetermined commands, the device can generate a response to the command rather than passing the command to the target. Additionally, the device can modify responses from the target to include additional data and indications of errors according to the command protocol supported by the initiator.
