
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.

Rebuilding Redundant Information

Does my controller support this feature? See "Supported Features."

If you have a redundant virtual disk, you can reconstruct the contents of a failed physical disk onto a new disk or a hot spare. A rebuild can take place during
normal operation, but it will degrade performance. The following sections provide additional information on rebuilding disks.
l "Replacing a Failed Disk" describes how to replace a failed physical disk and initiate a rebuild.
l "Set Rebuild Rate" describes how to set the rebuild rate on selected controllers.
l "A Rebuild Does Not Work" describes situations in which a rebuild will not work.

Virtual Disk Properties

The virtual disk properties can vary depending on the model of the controller. Virtual disk properties may include:

Property
Definition
Status
These icons represent the severity or health of the storage component.




Normal/OK

Warning/Non-critical

Critical/Fatal
See "Storage Component Severity" for more information.
Name
This property displays the virtual disk name.
State
This property displays the current status of the virtual disk. Possible values are:
Ready — The virtual disk is functioning normally.
Degraded — A physical disk in a redundant virtual disk is not online.
Resynching — A consistency check is being performed on the virtual disk.
On the PERC 3/Si, 3/Di, and CERC SATA1.5/6ch controllers, reconfiguring a concatenated virtual disk to a RAID 1 may cause the virtual disk to be
in Resynching state. Performing a "Cancel Check Consistency" on a virtual disk while it is in Resynching state will cause the virtual disk to be in a
Failed Redundancy state. See "Considerations for Concatenated to RAID 1 Reconfiguration on PERC 3/Si, 3/Di, and CERC SATA1.5/6ch
Controllers" for more information.
