4.9. Resolving Conflict
When a RAID set is created, the metadata written to the disk includes drive connection
information (Primary and Secondary). If, after a disk failure, the replacement disk was previously
part of a RAID set (or used in another system), it may have conflicting metadata, specifically in
reference to the drive connection information. If so, this will prohibit the RAID set from being
either created or rebuilt, In order for the RAID set to function properly, this old metadata must be
first overwritten with the new metadata. To resolve this, select Resolve Conflicts, and the correct
metadata, including the correct drive connection information, will be written to the replacement
disk.
