Enabling Pre-read Redundancy Check

Use the Pre-read Redundancy Check option to define the capability of a to pre-read logical drive information and determine if the data of that logical drive is consistent. A logical drive that has this feature enabled returns read errors if the data is determined inconsistent by the controller firmware.

If a logical drive that is configured with pre-read is migrated to a that does not maintain redundancy information, the metadata of the logical drive continues to reflect the feature property. Reads to that logical drive will ignore redundancy pre-read. If the logical drive is subsequently migrated back to a RAID type that supports redundancy, the feature will become available again.
