53 Intel® RAID Software User Guide
Note: Intel strongly recommends that you create global hot spare disks for all mirrored volumes
to increase the level of data protection. If a disk in a mirrored volume fails, the Integrated
RAID firmware rebuilds it using one of the global hot spares, and the data is safe. If you
create two mirrored volumes on an Intel SAS-3 controller, either of the volumes can use
the global hot spares if a disk fails.
6.2.2.1 Creating an Integrated Mirroring Volume
Follow these steps to create a two-disk Integrated Mirroring (RAID 1) volume with the
SAS3 BIOS CU. The steps begin with the Adapter List window that appears when the
SAS3 BIOS CU starts.
1. On the Adapter List window, use the arrow keys to se
lect an Intel SAS-3 adapter,
and then press Enter.
The Adapter Properties window appears
, as the following figure shows.

2. Use the arrow keys to select R
AID Properties, and then press Enter.
The Select New Volume Type window appears.
3. Select Cr
eate RAID 1 Volume.
The Create New Volume window appears.
4. Move the cursor to the RAID Disk column and
select a line that has a No entry in
this column, indicating that the disk is not already part of the volume you are
creating. To add the disk to the new volume, change the No to Yes by pressing the
space bar.
This disk is the Primary disk in
the volume.
Caution: The SAS3
BIOS CU deletes all existing data from the disks drives when you
select them to use in a mirrored volume.
5. Move the cursor to another line and press the
space bar to add the second disk to the
volume.
