3.2.2 Creating an Integrated Mirroring
Enhanced or Integrated Mir
Striping Volume
Integrated Mirroring Enhanced volumes can have from three-to-ten physical disks.
Data is written to a disk and mirrored on an adjacent disk. Integrated Mir
Striping volumes can have a minimum of four and a maximum of 10 physical disks, in
even numbers. In an Integrated Mirroring Enhanced or Integrated Mir Striping
volume, the data is both mirrored and striped.
Follow these steps to create an Integrated Mirroring Enhanced (RAID 1E) or Integrated
Mir Striping (RAID 10) volume with the SAS2 BIOS CU. The steps begin with the
Adapter List window that appears when the configuration utility starts:
1. On the Adapter List window, use the arrow keys to select an LSI SAS adapter, and
then press
Enter
.
The Adapter Properties window appears, as shown in
Figure 5
.
2. Use the arrow keys to select
RAID Properties
, and then press
Enter
.
The Create Array window appears.
3. Select
Create RAID 1E Volume
.
The Create New Array window appears.
