Unsuccessful storage media movement handling in automated removable storage media environments
Embodiments disclosed herein provide systems, methods, and computer readable media to handle unsuccessful movements of removable storage media in an automated removable media system. In a particular embodiment, a method provides receiving one or more user provided parameters that indicate one or more types of unsuccessful media move operations that should be reported as successful. The method further provides receiving a first request to move a first item of removable storage media from a first position in the automated removable media system to a second position in the automated removable media system and initiating a first move operation of the first item from the first position to the second position by at least one changer device. The method then provides determining that the first move operation resulted in one of the one or more types of unsuccessful media move operations and indicating that the first move operation was successful in response to the first request.
1. A method of operating a system for moving items of removable storage media in an automated removable media system, the method comprising:
in a processing system:
receiving one or more user provided parameters that indicate one or more types of unsuccessful media move operations that should be reported as successful;
receiving a first request to move a first item of removable storage media from a first position in the automated removable media system to a second position in the automated removable media system;
initiating a first move operation of the first item from the first position to the second position by at least one changer device;
determining that the first move operation resulted in one of the one or more types of unsuccessful media move operations; and
indicating that the first move operation was successful in response to the first request.
2. The method of claim 1 , further comprising:
determining an alternative position in the automated removable media system to which the first item was moved.
3. The method of claim 2 , further comprising:
receiving a second request; and
before handling the second request, indicating that the first item is located in the alternative position.
4. The method of claim 3 , wherein indicating that the first item is located in the alternative position comprises:
reporting a Small Computer System Interface (SCSI) Unit Attention (UA) code indicating that a status of at least one item of removable storage media has changed; and
providing the alternative position as a status of the first item.
5. The method of claim 1 , wherein the first position and the second position each comprise one of a media storage position type, a media import/export position type, and a data transfer position type.
6. The method of claim 1 , wherein at least one of the one or more types of unsuccessful media move operations that should be reported as successful comprises an unsuccessful media move operation wherein the second position comprises the media storage position type or the import/export position type but not the data transfer position type.
7. The method of claim 1 , wherein the one or more user provided parameters indicate that unsuccessful media move operations that require a specific position for the second position should be reported as unsuccessful.
8. The method of claim 1 , wherein the one or more user provided parameters indicate that unsuccessful media move operations associated with a certain application should be reported as unsuccessful.
9. The method of claim 1 , wherein the first request comprises a Small Computer System Interface (SCSI) move command.
10. The method of claim 1 , wherein the first item comprises a magnetic tape cartridge, the automated removable media system comprises a robotic tape library, and the at least one changer device comprises a robotic arm.
11. A system for moving items of removable storage media in an automated removable media system, the system comprising:
one or more computer readable storage media;
a processing system operatively coupled with the one or more computer readable storage media; and
program instructions stored on the one or more computer readable storage media that, when read and executed by the processing system, direct the processing system to:
receive one or more user provided parameters that indicate one or more types unsuccessful media move operations that should be reported as successful;
receive a first request to move a first item of removable storage media from a first position in the automated removable media system to a second position in the automated removable media system;
initiate a first move operation of the first item from the first position to the second position by at least one changer device;
determine that the first move operation resulted in one of the one or more types of unsuccessful media move operations; and
indicate that the first move operation was successful in response to the first request.
12. The system of claim 11 , further comprising:
determining an alternative position in the automated removable media system to which the first item was moved.
13. The system of claim 12 , further comprising:
receiving a second request;
before handling the second request, indicating that the first item is located in the alternative position.
14. The system of claim 13 , wherein indicating that the first item is located in the alternative position comprises:
reporting a Small Computer System Interface (SCSI) Unit Attention (UA) code indicating that a status of at least one item of removable storage media has changed; and
providing the alternative position as a status of the first item.
15. The system of claim 11 , wherein the first position and the second position each comprise one of a media storage position type, a media import/export position type, and a data transfer position type.
16. The system of claim 11 , wherein at least one of the one or more types of unsuccessful media move operations that should be reported as successful comprises an unsuccessful media move operation wherein the second position comprises the media storage position type or the import/export position type but not the data transfer position type.
17. The system of claim 11 , wherein the one or more user provided parameters indicate that unsuccessful media move operations that require a specific position for the second position should be reported as unsuccessful.
18. The system of claim 11 , wherein the one or more user provided parameters indicate that unsuccessful media move operations associated with a certain application should be reported as unsuccessful.
19. The system of claim 11 , wherein the first request comprises a Small Computer System Interface (SCSI) move command.
20. The system of claim 11 , wherein the first item comprises a magnetic tape cartridge, the automated removable media system comprises a robotic tape library, and the at least one changer device comprises a robotic arm.
