Method for extended diagnostic overlay control for tape storage devices

摘要

According to one embodiment, a method includes monitoring a plurality of parameters relating to operation of a tape drive to collect data from the operation of the tape drive, receiving a specification of one or more user-specified parameters to log during one or more collection windows, wherein the one or more user-specified parameters are specified from the plurality of parameters, logging at least some of the data collected from the operation of the tape drive to a memory during the one or more collection windows, wherein the at least some of the data collected is stored in a tape map comprising a plurality of fields, the plurality of fields including at least one histogram field, at least one per-channel field, and at least one per-channel indicator field, and dynamically overlaying one or more fields from the plurality of fields with data collected from the one or more user-specified parameters.
