Avago Technologies 3ware SAS 9750-16i4e - Manual (Page 259)

Error and Notification Messages
www.lsi.com/channel/products 247
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.
Action
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.

Warning
Cause
A drive was physically removed from the controller while the controller was
powered on.
Action
If the drive is not part of a redundant unit, return the drive as soon as possible.
You may need to rescan the controller to have the drive recognized. If at all
possible, do not remove a drive from a non-redundant unit as this may cause
data loss or a system hang.
