B. Creating Arrays
Before creating arrays, make sure the disks for the array are connected and
installed in your system. Note that disks with no usable space, or disks that are
not initialized are shown in gray and cannot be used. See Initializing Disk
Drives.
To create an array
1. Turn on your computer and press Ctrl+A when prompted to access the ARC
utility.
2. From the ARC menu, select Array Configuration Utility (ACU).
3. From the ACU menu, select Create Array.
4. Select the disks for the new array and press Insert. To deselect any disk,
highlight the disk and press Delete.
5. Press Enter when both disks for the new array are selected. The Array
Properties menu displays.
Assigning Array Properties
(*Note: Once the array is created and its properties are assigned, you cannot
change the array properties using the ACU. Instead, use Adaptec Storage
Manager - Browser Edition.)
To assign properties to the new array:
1. In the Array Properties menu, select an array type and press Enter. Note that
only the available array types, RAID 0 and RAID 1 are displayed. Each of these
types requires two drives.
2. Type in an optional label for the array and press Enter.
3. For RAID 0, select the desired stripe size. Available stripe sizes are 16, 32,
and 64 KB (default).
(*Note: Adaptec recommends that you do not change the default.)
4. Create RAID via allows you to select between the different creation methods
for RAID 0 and RAID 1. The following table gives examples of when each is
appropriate.
Raid Level Create Via
RAID 0
No Init
RAID 0
Migrate

RAID 1

Note 1. If you select Migrate for RAID 0, or Build for RAID 1, you will be asked
to select the source drive. The contents of the source drive will be preserved.
However, the data on the new drive will be lost.
