Tape library initiated actions
View Patent ↗Example apparatus and methods concern a tape library that can initiate an action. One example method may include controlling a tape library to perform a media scanning operation associated with an extended data life management policy. The extended data life management operation may be associated with an application representation of tape drives, slots, and tapes on the tape library. The method may include determining a result of the media scanning operation and selectively controlling the tape library to either provide status or to issue a command based on the result. In one example, conventional status may be returned when a media scan operation result (e.g., tape scan) indicates the tape is fine while a command may be issued when the result indicates the tape may need to be fixed, copied, or replaced.
1. A method, comprising:
controlling a tape library to perform a media scanning operation associated with an extended data life management policy, where the media scanning operation is performed on a tape that is not currently in use by an application and where the media scanning operation is performed using a tape drive that is not a member of an application representation available to the application, where the application is a data management application that provides content sharing, data archiving, and data de-duplication for a shared file system configured to operate in a storage area network;
determining a result of the media scanning operation; and
selectively controlling the tape library to perform one of:
providing status concerning the result to an application external to the tape library; and
issuing a command to the application external to the tape library, where the command is a copy media command that is available for invocation by the tape library through an application programming interface provided by the application external to the tape library, and where the copy media command is issued upon determining that the result indicated a failure of the media scanning operation.
2. The method of claim 1 , where the extended data life management policy controls one or more of, selecting a tape to be scanned, when the tape is to be scanned, and how the tape is to be scanned.
3. The method of claim 2 , where the extended data life management policy also controls one or more of, whether status concerning the result will be provided to the application, and whether the command will be issued to the application.
4. The method of claim 3 , where the extended data life management policy is associated with an application representation associated with the tape library, where the application representation presents to the application a logical set of tape drives, slots, and tapes, the logical set of tape drives, slots, and tapes comprising less than the total set of tape drives, slots, and tapes in the tape library.
