Resolving Conflicts
When a RAID set is created, then metadata written to the disk includes drive connection
information. 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. 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, from the main BIOS window
select
Resolve Conflicts, then press Enter, the correct metadata, including the correct drive
connection information, will be written to the replacement disk.
Low Level Format
Low Level Format is build into the RAID BIOS to make it more convenient to erase the entire
contents of a hard disk drive, including data, drive and partition information. The Low Level
Format utility works on single hard drive only, before the RAID set is configured.
