Creating Raid Sets; Resolving Conflicts - Asus P4G8X User Manual

Creating RAID Sets

1. Select the option Create RAID Set.
2. Choose either a Striped or Mirrored RAID Set.
3. You may choose to auto-configure or manually configure the RAID Set.
For Striped Sets, you can change the chunk size. For Mirrored Sets,
you can specify the Source and Target drives, and create a Disk Copy.
What is a chunk? The chunk size is the "stripe" on each disk. It is the
unit of storage equivalent to one stripe on a RAID 0 set. Available
chunk sizes: [2] [4] [8] [16] [32] [64] [128]
When manually setting the chunk size for your RAID set, it is
recommended to use the smaller chunk size for server applications
and the larger chunk size for AV applications.
What is Disk Copy? If the disk assigned as the Source drive has been
previously partitioned and has data stored in it, and a second drive is
added, the data on the source drive can be copied to the Target drive.
This makes the Source and the Target drives identical. All subsequent
data will be written to both drives as a Mirrored set. However, if the
Source drive does not have data stored in it, there is no need for Disk
Copy.
4. When the utility prompts you with "Are You Sure? (Y/N)" before
completing the configuration, press "Y" to confirm or "N" to return to the
configuration options.
Deleting RAID Sets
1. To remove one or more RAID sets, select the option Delete RAID Set.
2. Select the RAID set to delete, and press "Y" when asked "Are You
Sure? (Y/N)."

Resolving Conflicts

When a RAID set is created, the metadata written to the disk includes
drive connection information (Primary Chanel, Secondary Chanel). 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
the drive connection information. If so, this will a RAID set can neither be
created nor 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 the option Resolve Conflict so that the correct metadata (including
the correct drive connection information) may be written to the
replacement disk.
