Error information record storage for persistence across power loss when operating system files are inaccessible

摘要

Records such as error information records are stored across a power loss in a data storage system so that the records can be retrieved following a power loss without the use of a file management system of an operating system of the data storage system. Records are generated for system events such as errors, buffered, and stored in a raw data storage device such as a disk device without the use of a file management system. Following a power loss and subsequent restoring of power, the records are read again without the benefit of the file management system, and processed.
