Virtual Disks 223

Exceptions for Reconfiguring a Concatenated Virtual Disk on CERC SATA1.5/6ch

and CERC SATA1.5/2s Controllers

You can create a concatenated virtual disk by performing a Split Mirror or an

Unmirror on a RAID 1-concatenated virtual disk. After you have done so,

however, the resulting concatenated virtual disks cannot be subjected to any

further modification. You cannot reconfigure or add disks to the resulting

concatenated virtual disks.

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:

Locate the controller on which the virtual disk resides in the tree view.

Expand the controller object until the

Virtual Disks

object is displayed.

Select the

Check Consistency

task from the virtual disk’s drop-down

menu and click
