Selecting an Array
The first step in creating an individual logical drive from unconfigured
capacity is to define an array. To define the array, you specify two parameters: RAID level and
capacity.
Important: This dialog is available only when you are creating logical drives from
the Unconfigured Capacity node. If you are creating a logical drive on an existing array using a Free Capacity
node, this dialog is by-passed because the array (and its associated drives and RAID level) have already
been specified. For a Free Capacity node, the only dialog that is displayed is the Specify Logical Drive Parameters
dialog.

Specify the RAID level that will meet your data storage and protection requirements.
RAID level choices include RAID 0, RAID 1,
RAID 3, and RAID 5. |
2 |
Select a method for defining the available drives to be used in the array.
Note: By default, the automatic method is selected.

Description and Action |
Automatic |
Description |
Allows you to select from a list of array capacity choices as selected by the controller firmware.
A table displays array capacities, the number of drives that comprise the array, and whether or not
the array has channel protection.
Note: Your choice of RAID level affects the capacities of the listed arrays. |

Description |
Important: This option should only be used by experts who understand the concepts
of drive redundancy and optimal drive configurations.
Allows you to select which specific drives comprise the array. A table displays drive location information
and individual drive capacities.
Note: Your choice of RAID level affects the resulting capacity of the array. |
Action |
1 |
Select the number of drives you want to include in the array and then select Apply.
Result: The area next to the Apply button displays the corresponding array capacity and whether
the array has channel protection.
Important: If you do not select the appropriate number of drives for the chosen
RAID level, an error message is displayed. Change your drive selections and select Apply again. |
