System and Method for Identifying Failing Drives or Media in Media Library

摘要

Embodiments of methods and systems comprise identifying failing media and/or drives for a media library. Error data can be collected from media libraries. For each tape exhibiting an error rate of interest, a determination can be made whether the tape would still have been of interest had it not been loaded in certain drives. This information can be analyzed to identify failing drives or tapes.

主权项

1. A method of identifying failing media library components, comprising:
issuing SCSI commands to query one or more library components of a media library at intervals and receiving returned data; determining media and drive combinations, and error rates for the media and drive combinations, from the returned data; identifying a media in the media and drive combinations that experienced an error rate greater than a first threshold error rate; determining drive impact data for the media that indicates whether the media would still have experienced greater than the first threshold error rate had that media not been loaded in one or more drives in which the media was loaded; and for a drive in the media and drive combinations in which the media was loaded, identifying whether the drive is suspected of causing the media to have experienced greater than the first threshold error rate based on the drive impact data.
