Abstract
Embodiments of the present invention provide a method for monitoring components in a library by tracking the movement of library components. By tracking the movement of library components, the degradation of library components can be monitored and the reliability of library components determined, allowing unreliable components to be bypassed or replaced, enhancing the reliability of the library and preventing data loss.
Claims21
A method of monitoring library components implemented using non-transitory machine-readable media comprising:
- sending a plurality of Read Element Status commands to a media library over a period of time, the media library comprising library components, the library components comprising a plurality of drives and a plurality of tape cartridges;
- tracking movement of tape cartridges in the media library based on differences between library states returned in response to Read Element Status commands, wherein each of the returned library states comprises a current location of tape cartridges in the media library;
- correlating errors appearing at library components with the tape cartridges based on the movement of the tape cartridges;
- and
- identifying a component of the media library as an error source based on the correlation.
A system for monitoring library components, comprising a processor and a computer readable medium storing computer instructions executable to:
- send a plurality of Read Element Status commands to a media library over a period of time, the media library comprising library components, the library components comprising a plurality of drives and a plurality of tape cartridges;
- track movement of tape cartridges in the media library based on differences between library states returned in response to Read Element Status commands, wherein each of the returned library states comprises a current location of tape cartridges in the media library;
- correlating errors appearing at library components with the tape cartridges based on the movement of the tape cartridges;
- and
- identify a component of the media library as an error source based on the correlation.
A computer program product comprising a non-transitory computer readable medium storing a set of computer instructions, the set of computer instructions comprising computer instructions executable by a computer processor to:
- send a plurality of Read Element Status commands to a media library over a period of time, the media library comprising library components, the library components comprising a plurality of drives and a plurality of tape cartridges;
- track movement of tape cartridges in the media library based on differences between library states returned in response to Read Element Status commands, wherein each of the returned library states comprises a current location of tape cartridges in the library;
- correlating errors appearing at library components with the tape cartridges based on the movement of the tape cartridges;
- and
- identify a component of the media library as an error source based on the correlation.
