Chapter 7: Integrated Mirroring and Integrated Mirroring Enhanced

Locating Drives in a Volume

You can use the SAS BIOS CU to locate and identify a specific physical disk drive

by flashing the drive’s LED. You can also use the SAS BIOS CU to flash the LEDs of

all the disk drives in a RAID volume. There are several ways to do this:

• When you are creating an IM or IME volume, and a disk drive is set to Yes as part of

the volume, the LED on the disk drive is flashing. The LED is turned off when you

have finished creating the volume.

• You can locate individual disk drives from the SAS Topology screen. To do this,

move the cursor to the name of the disk in the Device Identifier column and press

Enter. The LED on the disk flashes until the next key is pressed.

• You can locate all the disk drives in a volume by selecting the volume on the SAS

Topology screen. The LEDs flash on all disk drives in the volume.

Selecting a Boot Disk

You can select a boot disk in the SAS Topology screen. This disk is then moved to scan

ID 0 on the next boot, and remains at this position. This makes it easier to set BIOS boot

device options and to keep the boot device constant during device additions and

removals. There can be only one boot disk.

Follow these steps to select a boot disk:

1. In the SAS BIOS CU, select an adapter from the A

DAPTER LIST.

2. Select the SAS TOPOLOGY option.

The current topology is displayed. If the selection of a boot device is supported, the

bottom of the screen lists the A

LT+B option. This is the key for toggling the boot

device. If a device is currently configured as the boot device, the D

EVICE INFO

column on the SAS T

OPOLOGY screen will show the word Boot.

3. To select a boot disk, move the cursor to the disk and press ALT+B.

4. To remove the boot designator, move the cursor down to the current boot disk and

press A

LT+B. This controller will no longer have a disk designated as boot.

5. To change the boot disk, move the cursor to the new boot disk and press ALT+B.

The boot designator will move to this disk.

NOTE: The LEDs on the disk drives will flash as described above if the

firmware is correctly configured and the drives or the disk enclosure supports

disk location.

NOTE: The firmware must be configured correctly in order for the ALT+B

feature to work.
