Replace Member on predictive failure can help ensure your virtual drive health stays optimal.

A Replace Member operation can occur when there is a SMART predictive failure reporting on a drive in a virtual disk.
How the option works
The automatic Replace Member is initiated when the first SMART error occurs on a physical disk that is part of a virtual disk. The target drive needs to be a hot spare that qualifies as a rebuild drive. The physical disk with the SMART error is marked as failed only after the successful completion of the Replace Member. This avoids putting the array in degraded status.
If an automatic Replace Member occurs using a source drive that was originally a hot spare (that was used in a rebuild), and a new drive added for the Replace Member operation as the target drive, the hot spare reverts to the hot spare state after a successful Replace Member operation.
