Automatic Replace Member with predicted failure
An Automatic Replace Member feature is triggered when there is a SMART predictive failure reported on the VD of a PD. The Automatic Replace Member featuerd is initiated when the first SMART error occurs on a physical disk that is part of a virtual disk. The target disk needs to be a hot-spare that qualifies as a rebuild disk. The physical disk with the SMART error is marked as failed only after the successful completion of the replacement task. This prevents the array from reaching degraded state.
If an Automatic Replace Member operation occurs using a source disk that was originally a hot-spare (that was used in a rebuild), and a new disk is added and set as a target disk for the replace member operation, the hot-spare drive will revert to the hot-spare state after the operation completes.
NOTE:To enable the Automatic Replace Member feature, use the Dell OpenManage Storage Management application.
