Predictive Failure is Seen in the Intel® RAID Controller Event Logs

Environment

Intel® RAID Controllers

BUILT IN - ARTICLE INTRO SECOND COMPONENT
Summary

When predictive failure happens, it is recommended to replace the corresponding disk/drive in the RAID array.

Description

RAID Event logs show Controller ID: 0 PD Predictive Failure: Port X – X:X:X warnings although the disks and virtual drives are online/optimal.

Note

Predictive Failure (ID 96) might be seen in the RAID logs.

Resolution

It is recommended that you back up your RAID array and replace the drive as early as possible.

Predictive failure happens when specific Self-Monitoring Analysis and Reporting Technology (SMART) attributes of a drive reached a predefined threshold (varies by drive/disk manufacturer). This is typically an indication or warning that the corresponding drive may fail in the near future even though it is still functional at the moment.

Note
  • Port X – X:X:X: The X shows information that can be used to identify the drive, such as the ID of the controller, enclosure, and slot that the drive is connected to.
  • One of the Fault Tolerant Features of the Intel® RAID Controller is the SMART technology. This provides a higher level of predictive failure analysis. For more information, refer to the Intel® RAID Software User Guide.
Additional information

It is possible that there are internal errors on a disk, which could eventually worsen its state and that of the virtual drive it belongs to.
