Selecting Segments for New Arrays
To select one or more segments to assign as members of the new
array:
1 Use the arrow keys to select a channel.
2 Use the arrow
keys to select the drives to assign to the new
array and press Insert.
The ACU displays the largest usable space available for each
drive. You can use some or all of the available space from
multiple drives to create the new array.
To deselect a drive, highlight the drive and press Delete.
Note: Drives containing MS-DOS partitions, drives with no
available space, or uninitialized drives appear dimmed and
cannot be selected when creating a new array.
3 Press Enter when you have selected all segments for the new
array. The ACU displays the Array Properties menu.
Assigning Array Properties
To assign properties to the new array:
1 From the Array Properties menu, select an array type and press
Enter. The display shows only the array types available for the
number of drives selected.
The controller supports four drives. The maximum number of
drives allowed and minimum number of drives required
depends on the RAID level, as described in the table below.
