Creating Logical Drive Freely

The Universal RAID Utility supports "Create Logical Drive - Custom Mode" in which a Logical Drive can be created as

required by specifying the setting items of the Logical Drive closely.

"Create Logical Drive - Custom Mode" allows you to create a Logical Drive by specifying the setting items of the Logical

Drive closely. It can also be used to create Logical Drives of several RAID Levels or create a Logical Drive by using

unused area of Disk Array. In addition, "Create Logical Drive - Custom Mode" enables more than one Logical Drive to be

created at a time.

The benefits of creating Logical Drives by "Create Logical Drive - Custom Mode" are as follows:

Allows to specify Logical Drives of various RAID Levels (RAID 0, RAID 1, RAID 5, RAID 6, RAID 10, RAID 50 and RAID 60) to

be created.

Allows to specify selection items (including Capacity, Stripe Size, Cache Mode and Initialize Mode) to be specified closely.

Allows to specify not only unused Physical Devices but also unused area of Disk Array to be used to create a Logical Drive

of RAID 0, RAID 1, RAID 5, or RAID 6.

Allows to specify more than one Logical Drive to be created by a set of operations (only RAID Viewer).

Ex. Create a Logical Drive of RAID 10, RAID 50 or RAID 60.

- Allows only unused Physical Devices (only RAID Viewer).

- Allows not only unused Physical Devices but also unused area of Disk Array (only raidcmd).

Ex. Create a Logical Drive of RAID 10.

- Allows four Physical Drives (only RAID Viewer).

- Allows even-numbered Physical Devices equal to or greater than three (e.g.: 4, 6, 8, …) (only raidcmd).

Operation Procedure of "Create Logical Drive - Custom

Mode"

This section describes the procedure of creating a Logical Drive by "Create Logical Drive - Custom Mode".

"Create Logical Drive - Custom Mode" is available only in the Advanced Mode.

RAID Viewer

Step 1 Connect Physical Devices used for a Logical Drive to the RAID Controller before starting the RAID Viewer if

required. If the Physical Devices are connected completely, start the RAID Viewer.

Step 2 Change the RAID System Management

Mode to the Advanced Mode if it is set to the Standard

Mode. To do this, click [Advanced Mode] on the [Tool]

menu.

Click a RAID Controller on the Tree View, select [Create

Logical Drive] on the [Control] menu, and click [Custom...].

Step 3 The [Create Logical Drive (Custom)]

dialog box is started. In the Custom Mode, register a

Logical Drive to be created to the list of the dialog

box. If the Logical Drive may be registered, click [Add].

To delete a registered Logical Drive, click the Logical

Drive to be deleted and click [Delete].
