Abstract

In a method for displaying menus on a storage automation library, a user'"'"'s input to the library is processed and, in response thereto, either 1) a menu derived from a local menu structure is displayed, or 2) a remote menu mode is activated. Between activation and deactivation of the remote menu mode, the library waits for a remote host to return remote menu data. A method by which a remote host retrieves the status of such an indicator, and apparatus for implementing these and other related methods, are also disclosed.

Claims

1. Remote host apparatus for providing menu data to a storage automation library, comprising:

computer readable storage media; and

program code stored on the computer readable storage media, comprising;

code to periodically poll a command I/O interface of the storage automation library to extract therefrom a remote menu mode status and stored user input; and

code to provide menu data to the command I/O interface, in response to a determination that an extracted remote menu mode status is “

active”

, wherein the remote menu mode is activated when a local menu structure in the storage automation library does not provide access to updated features for the storage automation library.

2. The apparatus of claim 1, wherein the program code further comprises code, responsive to the extracted user input, to cause the storage automation library to reset the remote menu mode status to “

inactive”

.

3. The apparatus of claim 1, wherein the code to poll the command I/O interface issues SCSI Read_Buffer commands, and wherein the code to provide menu data to the command I/O interface issues SCSI Write_Buffer commands.

4. The apparatus of claim 1, wherein said code undertakes communications with the command I/O interface via TCP/IP over a packetized SCSI protocol.

5. The apparatus of claim 1, wherein the extracted user input comprises stored keystrokes.

6. The apparatus of claim 1, wherein the menu data comprises extended help information.

7. The apparatus of claim 1, wherein the program code further comprises code, responsive to the extracted user input, to execute diagnostic tests for the storage automation library.

8. The apparatus of claim 1, wherein the program code further comprises code, responsive to the extracted user input, to provide configuration commands to the storage automation library.

9. The apparatus of claim 1, wherein the program code further comprises code, responsive to the extracted user input, to provide firmware updates to the storage automation library.

10. A method for providing menu data to a storage automation library, comprising:

via a remote host, periodically polling the storage automation library to extract therefrom a remote menu mode status and stored user input, if any; and

via the remote host, providing menu data to the storage automation library, in response to a determination by the remote host that an extracted remote menu mode status is “

active”

, and in response to the remote host'"'"'s processing of the extracted user input, if any, wherein the remote menu mode is activated when a local menu structure in the storage automation library does not provide access to updated features for the storage automation library.

11. The method of claim 10, wherein at least some of the menu data provided to the storage automation library defines a user-selectable remote menu exit function for display by the storage automation library.

12. The method of claim 11, wherein the menu data comprises code that links selection of the remote menu exit function to deactivation of the remote menu mode by the storage automation library, without further action from the remote host apparatus.
