DSA Error Log Manual

This manual provides a comprehensive guide for users with DSA level II and product training to understand and decode error log messages generated by Digital Storage Architecture (DSA) hardware products. It covers MSCP/TMSCP error logs for various operating systems, including VMS, RSTS (versions 8 & 9), RSX-11, TOPS (10 & 20), DSM-11, UNIX (Berkeley & System V), RT-11, and ULTRIX 32. Additionally, it explains miscellaneous error types like Last Fail, BIIC, Remanufactured MSCP Control, Unexpected End, and SA Register Reported errors. The document details common error log message fields crucial for accurate interpretation and provides specific decoding information for individual DSA hardware products such as RA60, RA80, RA81, RA82 disk drives, TA81, TA78, TK50 tape drives, and UDA50, KDA50-Q, KDB50, HSC50, HSC70, RC25, and RQDX3 controllers. The primary purpose of these error log reports is to offer essential error and status information for diagnosing hardware issues without requiring further diagnostics or interrupting operations.
