Exceptions for Reconfiguring a Concatenated Virtual Disk on PERC 3/Si, 3/Di, 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:

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.
