Decoding Intel® RAID Sense Code Messages Intel® RAID Controllers: SAS Software Stack 1. Decoding Intel® RAID Sense Code Messages 1.1 Purpose This document reviews unexpected sense codes returned by SAS/SATA RAID devices attached to an Intel® RAID Controller using the SAS software stack. This document does not describe all error types or messages generated by these RAID Controllers. 1.2 RAID Logs The RAID controller error events are logged as they occur.
Intel® RAID Controllers: SAS Software Stack Appendix A Sense Code Qualifier. These bytes can be decoded into an error message for more information. 5. The logged entry also includes the following: - Date and time of the event - Channel and target - SAS/SATA CDB - Returned Sense Code 6. Returned Sense Data includes: - Sense Key = byte 2 - Additional Sense code = byte 12 - Additional Sense Code Qualifier = byte 13 1.
