Self-Monitoring Analysis and Reporting
Technology (SMART)
Self-Monitoring Analysis and Reporting Technology (SMART) monitors the
internal performance of all physical disk components to detect faults
indicating the potential for physical disk failure. SMART uses this
information to report whether failure is imminent so that a physical disk can
be replaced before failure occurs. The RAID controller monitors all attached
drives and notifies users when a predicted failure is reported by a physical
disk.
Media Errors and Unreadable Sectors
If the RAID controller detects a media error while accessing data from a
physical disk that is a member of a disk group with a redundant RAID level

peer disks in the disk group and uses recovered data to correct the error. If the
