Techniques for generating action recommendations for a data tape system are disclosed. A data tape system generates action recommendations for a data tape based on library-based metadata messages as well as a measured data quality value of the data tape. The system initiates an operation resulting in the data tape interacting with a media drive. A data tape library controller generates one or more metadata messages based on a result of a requested operation. The metadata message may include information regarding the type of error and a default recommended course of action. The system generates the recommended action for the data tape using a trained machine learning model.

Data tape media quality validation and action recommendation

Techniques for generating action recommendations for a data tape system based on a media drive calibration are disclosed. A system receives a request to perform an operation including an exchange between a data tape and a media drive. If the system determines that the operation is a data tape validation operation, the system determines whether the media drive is calibrated. If the calibration value of the media drive does not meet a threshold, the system performs a calibration procedure. The system may calibrate the media drive or replace the media drive with a calibrated media drive. The system performs the validation operation. Based on a validation result, a data tape quality value, and the media drive calibration value, the system generates a recommended action for a data tape.

Data which is transmitted over the internet or other transmission networks is first divided up into individual information packets, transmitted and then reassembled into useful data after reception. Parity packets are included in with the information packets in the transmission of data in order to enable the regeneration of any information packets which were lost or damaged during transmission. The grouping of information packets and parity packets derived therefrom is termed a chunk. Chunk arrangements to recover from all cases of single and double lost packets are disclosed. Bursts of lost packets are recovered by interleaving the transmission of packets from different chunks. If the recovery is not successful then retransmission occurs in a manner similar to TCP.
