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. See "Virtual Disk Task: Reconfigure (Step 2 of 3)" for more information.

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."
