MS-7125 ATX Mainboard Rebuild RAID 1 Set This menu selection is used to initiate the copying of data from an existing drive to a replacement drive that has been installed in a RAID 1 set after the failure of one of the members. 1. Select "Rebuild RAID 1 set" 2. Select the desired set and press Enter. 3. Press "Y" when asked, "Are You Sure?" 4. The set will be rebuilt. The status of the rebuild is displayed in the MAIN MENU window. Resolving Conflicts When a RAID set is created, the metadata written to the disk includes drive connection information including the channel on the host adapter to which it is connected. 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 correct this, select "Resolve Conflict" and the correct metadata, including the correct drive connection information; will automatically be written to the replacement disk. 1. Select "Resolve Conflicts" and press Enter. 6-10

Resolving Conflicts
When a RAID set is created, the metadata written to the disk includes drive
connection information including the channel on the host adapter to which it is
connected. 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 correct this,
select “Resolve Conflict” and the correct metadata, including the correct drive
connection information; will automatically be written to the replacement disk.
1. Select “Resolve Conflicts” and press Enter.
