Abstract:
1. A method of managing retry commands communicated between a host computer and an automated data storage library, said host computer communicating with said automated data storage library using one or more control paths, and said automated data storage library including a library controller for controlling said automated data storage library, and wherein said automated data storage library includes data storage media and a means for transporting said data storage media, where said method comprises the steps of: said host computer sending a command to said automated data storage library using one of said one or more control paths; in response to said host not receiving a command completed successfully response, said host computer sending a retry of said command to said automated data storage library using any of said one or more control paths; said automated data storage library receiving and decoding said command, wherein said step of automated data storage library receiving and decoding said command further comprises said automated data storage library executing said retry of said command if said command is not a command to transport said data storage media; and said automated data storage library sending said command completed successfully response to said host computer without executing said retry of said command if said command was already executed in response to said command sent to said automated data storage library using said one of said one or more control paths.
