1. Review the information in "Starting and Target RAID Levels for Virtual Disk Reconfiguration."
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.
Starting and Target RAID Levels for Virtual Disk Reconfiguration
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."
Table 13-1.VirtualDiskReconfiguration
Maintain Integrity of Redundant Virtual Disks
Does my controller support this feature? See "Supported Features."
The virtual disk Check Consistency task verifies the accuracy of the redundant (parity) information. This task only applies to redundant virtual disks. When
necessary, the Check Consistency task rebuilds the redundant data.
To verify a virtual disk's redundant information:
1. Locate the controller on which the virtual disk resides in the tree view. Expand the controller object until the Virtual Disks object is displayed.
2. Select the Check Consistency task from the virtual disk's drop-down menu and click Execute.
