l Assign a hot spare to the virtual disk—When a virtual disk uses a redundant RAID level, then you can assign a hot spare (backup physical disk) to
rebuild data if a physical disk in the virtual disk fails. For more information, see:
¡ Protecting Your Virtual Disk with a Hot Spare—This section describes hot spares and includes controller-specific information.
l Perform a Check Consistency—The Maintain Integrity of Redundant Virtual Disks task verifies the accuracy of a virtual disk's redundant data.
l Reconfigure a Virtual Disk—You can add physical disks to a virtual disk to expand the virtual disk's capacity. You can also change RAID levels. For more
information, see Virtual Disk Task: Reconfigure (Step 1 of 3).
