Patent attributes
A method for monitoring and predicting health of tape drives and media in a tape library. The method includes receiving exchange data associated with an exchange in the tape library. Then the method includes, with an analytics module, processing the exchange data to determine gain types for the exchange. Based on the gain type, a health gain value is assigned to a tape drive and media and current suspicion level values are independently assigned to the tape drive and the media. The method includes assigning a first health indicator to the media and a second health indicator to the tape drive based on these two suspicion level values. In some embodiments of the method, the current suspicion level value calculating step includes summing the health gain value with a number of health gain values assigned to the tape drive and the media for up to a predefined number of monitored exchanges.
