Chapter 6: Configuring your RAID solutions
f
Press D
ELETE
to confirm erasing data from the disk or press any other key to deselect
the disk.
g
Repeat the Step 5 to select as many as four more disks for the IM volume. (Or select
as many as three more disks if you want to configure a hot spare disk for the
volume.)
6
(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.
7
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
Discard changes,
then exit this menu
.)
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 configuration utility lets you create one Integrated Striped volume
per controller.
■
An IS volume can have from two to six 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 in an IS volume must be connected to the same channel of the same
controller, and the controller must be in the BIOS boot order.
■
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 Kbytes.
