Fast initialization for quick array setup Consistency check for background data integrity Consistency Check verifies that all stripes in a virtual disk with a redundant RAID level are consistent.
Typically a RAID 5 array rebuilds when there is another drive that the degraded array can use to rebuild.
The consistency check will mirror data when an inconsistent stripe is detected for a RAID 1 and recreating the parity from the peer disks when in the case of a RAID 5. On controllers with many disks you typically can set global spares or spares dedicated to certain arrays letting you fine tune which drives can be used by which arrays to rebuild.
