Locating Disk Drives in a Volume Use the SAS3 BIOS CU to locate and identify a specific physical disk drive in a disk enclosure by flashing the drive's LED. Alternatively, use the SAS3 BIOS CU to flash the LEDs of all the disk drives in a RAID volume if they are in a disk enclosure. When you add a disk drive to a new mirrored volume, the LED on the disk drive starts flashing. The LED stops flashing when you finish creating the volume. To locate disk drives by flashing their LEDs, follow these steps: 1. Select the desired SAS-3 controller on the Adapter List window and press Enter. The Adapter Properties window appears. 2. Highlight SAS Topology, and press Enter. The SAS Topology window appears. 3. Select the disk in the Device Identifier column, and press Enter. The LED on the disk flashes until you press a key to stop it. 4. To identify all the disk drives in a volume, select the volume in the left column of the SAS Topology window, and press Enter. The LEDs flash on all disk drives in the volume until you press a key to stop them. Note: The LEDs on the disk drives flash, as previously described, if the firmware configuration is correct and the drives are in a disk enclosure. Selecting a Boot Disk You select a boot disk in the SAS Topology window. The next time you boot the computer, the firmware moves this disk to scan ID 0, making it the new boot disk. This feature makes it easier to set BIOS boot device options and to keep the boot device constant during device additions and removals. Optionally, you can select an alternative boot device. If the BIOS cannot find the preferred boot device when it loads, it attempts to boot from the alternative device. Follow these steps to select a boot disk: 1. In the SAS3 BIOS CU, select an adapter from the Adapter List. 2. Select the SAS Topology option. If a device is currently designated as the boot device, the Device Info column on the SAS Topology window lists the word Boot, as the following figure shows.
