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. |
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.

|
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.
