The 3ware RAID controller supports SMART monitoring for SATA and SAS drives, whereby the individual drives automatically monitor certain parametric information such as error rates and retry counts. This type of monitoring may be able to predict a drive failure before it happens, allowing you to schedule service of the unit before it becomes degraded. The SMART status of each drive attached to the 3ware RAID controller is monitored daily.

LSI recommends that you replace any drive that has exceeded the SMART threshold.

If the drive is part of a redundant unit, remove the drive through 3DM2 or CLI. Replace the drive and start a rebuild.

If the drive is not part of a redundant unit, then you will need to backup your data before replacing the drive.
