Does my controller support this feature? See Supported Features.
You can reconfigure or migrate a virtual disk in order to increase the disks capacity or change its RAID level.
To reconfigure a virtual disk:

1. Review the information in Starting and Target RAID Levels for Virtual Disk Reconfiguration and Capacity Expansion.

2. Locate the controller on which the virtual disk resides in the tree view. Expand the controller object until the Virtual Disks object is displayed.

3. Select the Reconfigure task from the virtual disk's drop-down menu and click Execute.

4. Complete the Reconfigure task using the Reconfigure wizard. For more information, see Virtual Disk Task: Reconfigure (Step 2 of 3).
Starting and Target RAID Levels for Virtual Disk Reconfiguration and Capacity
Expansion
After you have created a virtual disk, the possibilities for reconfiguring the virtual disk depend on the controller, RAID level, and available physical disks. The
following table describes the possible scenarios for reconfiguring a virtual disk. For more information on the RAID levels, see Choosing RAID Levels and
Concatenation.
