Creating Integrated Striping Volumes
1.1,Integrated Striping
Configuration Overview
The LSI SAS2 BIOS CU is a menu-driven utility program that enables you
to easily configure and manage Integrated RAID volumes. You can use the
SAS2 BIOS CU to create one or two Integrated Striping volumes on each
LSI SAS2 controller. Each volume can have from two-to-ten drives. All
disks in an Integrated Striping volume must be connected to the same LSI
SAS2 controller.
Although you can use disks of different size in Integrated Striping volumes,
the smallest disk in the volume determines the logical size of all disks in the
volume. In other words, the firmware does not use the excess space of the
larger member disk(s). For example, if you create an Integrated Striping
volume with two 100-GB disks and two 120-GB disks, the firmware uses
only 100 GB on each of the larger disks for the volume. The supported
stripe size is 64 kilobytes.
1.2 , Creating Integrated
Striping Volumes
The SAS2 BIOS CU is part of the Fusion-MPT BIOS. When the BIOS loads
during the startup sequence and you see the message about the LSI
Configuration Utility, press Ctrl-C to start the SAS2 BIOS CU. After you
do this, the message changes to:
Please wait, invoking SAS Configuration Utility...
After a brief pause, the main menu (Adapter List window) of the SAS2 BIOS
CU appears. On some systems, however, the following message appears
next:
Configuration Utility will load following
You can configure any combination of up to two Integrated Striping (RAID 0)
volumes and mirrored volumes on each LSI SAS2 controller, up to a
maximum of 14 physical disk drives for the two volumes. (This includes one
or two hot spare disks for mirrored arrays.)
The following guidelines apply when creating an Integrated Striping
volume:
※ All physical disks in an Integrated Striping volume must be either
SATA (with extended command set support) or SAS (with SMART
support). You cannot combine SAS and SATA disks in the same volume.
However, you can create one volume with SAS disks and a second volume
with SATA disks on the same controller.
※ Disks must have 512-byte blocks and must not have removable media.
※ Integrated Striping volumes must have at least two disks and no more
than 10 disks. Integrated Striping volumes do not support hot spare
disks.
Follow these steps to create a eght-disk Integrated Mirroring (RAID 0)
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 MultiCore
and then press Enter.
The Adapter Properties window appears, as the following figure shows.
2. Use the arrow keys to select RAID Properties, and then press Enter.
The Create Array window appears. 3. Select Create RAID 0 Volume. The Create New Array 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 being created. to add the disk to the new array, change the No to
Yes by pressing the space bar.
5. Press C to create the array. A menu screen appears.
6. From the menu options, select Save changes then exit this menu.
Deleting an Array
Follow these steps to delete a selected volume (array):
1. In the Adapter List window, use the arrow keys to select an LSI SAS adapter.
The Adapter Properties window appears.
2. Use the arrow keys to select RAID Properties, and then press Enter.
3. Select Manage Volume. and then press Enter.
5. Select Delete Volume. and then press Enter.
6. Press Y to delete the array, or press N to cancel the deletion process.
