In order to implement RAID functions, you must create a virtual disk. A virtual disk refers to storage
created by a RAID controller from one or more physical disks. Although a virtual disk may be created
from several physical disks, it is seen by the operating system as a single disk.
Before creating a virtual disk, you should be familiar with the information in Considerations Before
Creating Virtual Disks.
Storage Management provides wizards to help you create a virtual disk:
• The Create Virtual Disk Express Wizard calculates an appropriate virtual disk layout based on the
available space and controller considerations. Using this wizard, you can quickly create a virtual disk
using recommended selections.
• The Create Virtual Disk Advanced Wizard allows you to specify the read, write, and cache policy for
the virtual disk. You can also select the physical disks and the controller connector to be used. You
need a good knowledge of RAID levels and hardware to use the advanced wizard.

Reconfiguring or migrating a virtual disk enables you to increase the capacity or change the RAID level of
the virtual disk.
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 Tasks drop-down list box and click Execute.
