Follow these steps to activate a selected array.

1.Select ACTIVATE ARRAY on the MANAGE ARRAY screen.

2.Press Y to proceed with the activation, or press N to abandon it. After a pause, the array will become active.

WARNING: 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.

Locating a Disk 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 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.

•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.

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.
