14.The window shown in Figure 4-98 is used to create spanned arrays. Select
the base arrays which will be used to build a spanned array. Select Array-2
and Array-3 and assign them to the New spanned array. The New spanned
array tab will be renamed to S-array-1 and a new New spanned array tab is
created. Create another spanned array with Array-4 and Array-5. See
Figure 4-98. Click Next.

15.The window shown in Figure 4-99 on page 139 allows you to create logical
drives in all defined arrays. The first logical drive in each array is already
defined with the maximum logical drive size. Enter a meaningful device name.
Select the RAID level. This RAID level is determined by the number of drives
in the array. For a spanned array, the number of drives in the base array
determines if a RAID 10 or 50 will be defined. Specify how large the logical
drive will be. Choose the preferred controller.
For our example, use a logical drive name VOLGA-BOOT. Specify RAID level 1
and a size of 10GB for this logical drive. The logical drive and this array will be
owned by controller A.
