5.2.5.4.3 Deleting an Array

CAUTION

Before deleting an array, be sure to back up all data on the array that you want to keep.

Follow these steps to delete a selected array:

① Select Delete Array on the Manage Array screen.

② Press Y to delete the array, or press N to abandon the deletion. After a pause, the firmware deletes

the array.

Note

Once a volume has been deleted, it cannot be recovered. The master boot records of all disks are

deleted.

5.2.5.4.4 Locating a Disk Drive, or Multiple Disk 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:

z When you are creating an IS 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.

z 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.

z You can locate all the disk drives in a volume by selecting the volume on the RAID Properties

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

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.

5.2.5.4.5 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 Adapter 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 Alt+B option. This is the key for toggling the boot device. If a device is currently

configured as the boot device, the Device Info column on the SAS Topology screen will show the word

“Boot.”

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