If partitions are defined on this disk, a message warns you that data on the disk
will be lost when the mirrored volume is created. Press
Delete
to confirm erasing
data from the disk, or press any other key to deselect the disk. Continue with Step 5 .
5
(Optional) Use the arrow keys to select a hot spare disk for the IM volume. Select
Yes
as the value for the
Hot Spare
column.
6
When you have selected all disks for the IM volume, press E
SC
and select
Save changes,
then exit this menu.
(If you do not want to create the IM volume, select

The IM volume exists as soon as you save the changes. The RAID Properties screen
now displays the IM volume properties and status.
Integrated Striping configuration
The following must be considered when configuring the onboard SCSI RAID solution for
Integrated Striping:
■ The BIOS-based CU lets you create one Integrated Striped volume per controller.
■ An IS volume can have two or three disks.
■ Disks in an IS volume must be non-removable, single-LUN disks that support 512-byte
sectors, wide synchronous transfers, Qtag’d I/Os, and a unit serial number. The disks
must support SMART, and they must be minimally compliant with the SCSI-2
standard.
■ Disks of different size are allowed in IS volumes, but the smallest disk determines the
“logical” size of each disk in the volume. The excess space of larger member disks is
not used.
■ Usable disk space for each IS member disk is adjusted down to leave room for Meta
data. Usable disk space may be further reduced to maximize the ability to interchange
disks in the same size classification.
■ The supported stripe size is 64 Kb.
To configure the onboard SCSI RAID solution for Integrated Striping:
1
Open the BIOS Setup utility as described in the previous procedure.
2
On the Main menu screen, use the arrow keys to select an adapter, then press E
NTER
.
The Adapter Properties screen opens.
3
Use the arrow keys to select
RAID Properties
, then press E
NTER
. The RAID Properties
screen opens.
