Stop any robot test utilities, since they have the lock on the robotic device when they are active, and can block other requests.

Check whether excessive hardware retries have delayed the completion of a robotic command.

Check to see whether the robotic device still functions. Use a robot test utility to send commands to the device to see whether it is responsive. Execute vmps to verify that no unexpected Media Manager processes are running. Some processes should remain running, but some processes that do not go away can indicate a more serious problem, such as a hung system call.
