Extend logical drive

The logical drive extension feature allows the capacity of a logical drive to be expanded by using unused

space on existing disks, without requiring a reboot.

Increase the capacity of an existing logical drive by specifying a new size. Once the task is performed,

use operating system partitioning software to take advantage of the extended space available.

Enable this feature in the HPE MR Storage Administrator user interface using the Expand option within

the Logical Drive Actions menu.

Migrate RAID level

RAID level transformation is the process of converting one RAID configuration to another. You can

perform RAID level transformation at the array level.

The RAID level transformation feature allows you to change the current level of fault tolerance (RAID

type) for your logical drive. When the fault tolerance changes, you may have more or less unused space,

depending on the fault tolerance with which you started.

The following table describes the valid RAID level transformation matrix.

Initial RAID level

RAID 0

RAID 1

RAID 5

RAID 6

Transformation priority

As the transformation priority level increases, the rate at which requests from the operating system are

processed decreases. Transformation refers to array expansions, logical drive extensions, logical drive

migrations, and array shrink and move operations.

Access the transformation priority rate by selecting Set Adjustable Task Rate under the More Actions

menu then locating it under the Priority Percentage column. The default value is 30%. Enter a number

from 0 to 100 to control the rate at which transformation of a logical drive occurs. The higher the number,

the faster the transformation occurs (and the system I/O rate might be slower as a result).
