ABSTRACT:
A method and system for performing reliability analysis of disk drive failure mechanisms is provided. The information for performing the analysis is obtained in accordance with the invention from a database generated from identification information stored about individual drives, and drive families, that are deployed in the field. An error database stores error codes that are issued by a disk drive upon a particular event. These error codes are reported to a storage system administrator and recorded in the error database. The disk drive information and the error codes are mapped, and error codes are translated into failure mechanisms for a particular drive family. An analysis is performed whereby a hazard rate plot is provided for either all failure indicators or selected failure indicators or subpopulations for a particular drive family over a given time.
