Extended diagnostic overlay control for tape storage devices

摘要

According to one embodiment, a system includes a tape drive for reading from and/or writing to magnetic tape media, the tape drive having a memory and logic adapted for: monitoring parameters relating to operation of the tape drive to collect data from the operation of the tape drive, receiving a specification of an owner interface comprising a source of specifiable parameters, receiving one or more user-specified parameters from the owner interface to log during a collection window, logging at least some of the data collected from the operation of the tape drive to the memory during the collection window, wherein the at least some of the data collected is stored in a tape map including a plurality of fields, and dynamically overlaying one or more fields from the plurality of fields with data collected from the one or more user-specified parameters. The plurality of fields includes at least one histogram field, at least one per-channel field, and at least one per-channel indicator field.
