6 BIOS Configuration Utility
The BIOS Configuration Utility configures disk arrays and logical drives. Because the
utility resides in the BIOS, its operation is independent of the operating systems on your
computer.
The BIOS Configuration Utility is a character-based utility than you can run by pressing
<Ctrl><M> when the system boots. Use this utility to perform the following:
•
Create hot spare drives.
• Configure physical arrays and logical drives.
•
Initialize one or more logical drives.
•
Access controllers, logical drives, and, physical drives individually.
•
Rebuild failed hard drives.
•
Verify that the redundancy data in logical drives using RAID level 1 or 5 is correct.
•
Select a host adapter to work on.
Starting the BIOS Configuration Utility
When the host system boots, hold the <Ctrl> key and press the <M> key when the
following appears:
HA -0 (Bus 1 Dev 6) Type: Standard FW x.xx SDRAM=128MB
0 Logical Drives found on the Host Adapter
Adapter BIOS Disabled, No Logical Drives handled by BIOS
0 Logical Drive(s) handled by BIOS
Press <Ctrl><M> to Enable BIOS Configuration Utility
Press <Ctrl><H> to Enable WebBIOS
For each controller in the host system, the firmware version, dynamic random access
memory (DRAM) size, and the status of logical drives on that adapter display. If you do
not press <Ctrl><M> within a few seconds of the prompt, the system continues the boot
procedure.
After you press a key to continue, the Management Menu screen displays.
Configuring Arrays and Logical Drives
Perform the following steps to configure arrays and logical drives:
1. Designate hot spares (optional).
2. See "Designating Drives as Hot Spares" for more information.
3. Select a configuration method and create arrays using the available physical drives.
See "Selecting the Configuration Method" for more information.
4. Define logical drives using the space in the arrays.
5. Save the configuration information.
6. Initialize the new logical drives.
