Create Logical Drive Wizard: Specify Array Parameters

Related Topics

Use this screen to specify the RAID level and overall capacity of the new array.

Procedure

1

Specify the RAID level that meets your logical drive data storage and protection requirements.

RAID level choices include RAID 0 , RAID 1 , RAID 3 , and RAID 5 .

2

Select a method for defining which available drives to use in the array and perform the appropriate action as described in the following table.

The Automatic method is selected by default. If an unassigned drive was selected in the Physical View when the Create Logical Drive Wizard was started, the Manual method is selected by default.

Important: You cannot create arrays with certain RAID levels when the following are true:

  • You do not have enough unassigned drives with EQUAL capacities.
  • You are using the Automatic capacity selection method.

Use the Manual capacity selection method to configure an array using unassigned drives that do NOT have equal capacities.

Method

Description and Action

Automatic

Lets you select from a list of array capacity choices selected by the controller firmware. A table displays array capacities, and how many drives comprise the array.

Note: Your choice of RAID level affects the capacities of the listed arrays.

Action

Select one array and then select Next to continue the logical drive creation process.

Manual

Lets you 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.

Important:

  • This option should only be used by experts who understand drive redundancy and optimal drive configurations.
  • There are limits to how much drive space capacity you can have in a single array. These limits vary according to your host operating system. Consult the Product Release Notes for specific limits.

Action

a

Select the number of drives to include in the array and then select Apply.

Result: The area next to the Apply button displays the corresponding array capacity and the number of drives that will comprise the array.

Important: RAID level 1 requires an even number of drives, and RAID level 3 and level 5 require at least three drives. 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.

b

Select Next to continue the logical drive creation process.
