You will observe that many references are made to SCSI throughout this publication. This is because Fibre Channel transports the SCSI command set.

12.1 Self-Monitoring Analysis and Reporting Technology

Self-Monitoring Analysis and Reporting Technology (S.M.A.R.T.) is designed to recognize conditions that indi-cate imminent drive failure and provide sufficient warning to the host system of impending failure. The host system may use the information provided to trigger it to perform diagnostic, preventative, and/or protective functions (e.g., data backup).

The initiator sets up the parameters for S.M.A.R.T. operation using Mode Select Informational Exceptions Con-trol page 1Ch. The drive reports information about S.M.A.R.T. operation using Request Sense Additional Sense Code 5D 00 and Mode Sense data page 1Ch. Refer to SCSI Command Reference Manual, 100293068, sections 1.11, 1.12, 1.13, and 1.14 for descriptions of the Mode Select and Mode Sense commands. Refer to SCSI Command Reference Manual, 100293068, Section 1.16 for details on the Informational Exceptions Control page. Refer to the individual drive’s product manual to determine if your particular drive supports S.M.A.R.T. and the extent of its implementation of the S.M.A.R.T. system.
