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.
You cannot enable this feature for logical drives that do not contain redundancy information.
You can enable redundancy pre-read on a per-logical drive basis.
You can enable this check only for non-high-level logical drives.
You can enable this check for normal logical drives, , and .
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.
