ABSTRACT:
The present invention provides a method, apparatus and program product for improving reliability in RAID/Server systems by monitoring the RAID/Server system at the system level for predictive failure analysis (PFA) triggering events. Examples of PFA triggering events include: rebuild operations, addition of new disk drives, a change in usage patterns, and suspected handling damage. Once a triggering event is detected, the RAID/Server system issues a command to the disk drives in the system to begin performing PFA. If a PFA error is detected on any of the drives, the error is reported to the RAID/Server system.
