Self-Monitoring, Analysis, and Reporting Technology (S.M.A.R.T.) is available on many new SCSI disks. S.M.A.R.T. provides a way for disks to self-check certain physical conditions that are useful predictors of disk failure and send an alert to the SFW Event Log when conditions indicate that a failure may occur soon. This allows the system administrator to take preventive action to protect the data on the disk.

To receive alerts in the SFW Event Log, S.M.A.R.T. monitoring must be enabled for the global configuration and also on each disk you want checked. The default is to have S.M.A.R.T. monitoring disabled.
