NOTE: For a controller that has more than one channel, it may be possible to configure a virtual disk that is channel-
redundant.

the spun down state, the system displays a message that indicates the IDs of the spun down drives and the delay in
executing tasks on them.

the virtual disk capacity. To expand virtual disk capacity, click Expand Capacity.
2. Click Continue to go to the next page or Exit Wizard if you want to cancel.
To locate Reconfigure In Storage Management
1. In the Server Administrator window, under the system tree, expand Storage to display the controller objects.
2. Expand a controller object.
3. Select the Virtual Disks object.
4. Select Reconfigure from the Available Tasks drop-down box.
5. Click Execute.
Virtual Disk Task - Reconfigure Step 2 of 3
Does my controller support this feature? See Supported Features.
The virtual disk reconfigure Step 2 page enables you to select the RAID level and size for the reconfigured virtual disk. The
Expand Capacity option appears only for PERC H730P MX and PERC H745P MX controllers with firmware version 7.1 or later.
If you selected Expand Capacity in Step 1, this page allows you to expand the capacity of the virtual disk.
To Reconfigure a Virtual Disk (Changing the RAID Level and Size): Step 2 of 3
1. Select the new RAID level for the virtual disk The available RAID levels depend on the number or physical disks selected
and the controller. The following describes the possible RAID levels:
Depending on the controller, Concatenated enables you to combine the storage capacity of several disks or to create a
virtual disk using only a single physical disk. For information on whether the controller supports a single physical disk or
two or more when using Concatenated, see Number Of Physical Disks Per Virtual Disk. Using Concatenated does not
provide data redundancy nor does it affect the read and write performance.
Select RAID 0 for striping This selection groups n disks together as one large virtual disk with a total capacity of n
disks. Data is stored to the disks alternately so that they are evenly distributed. Data redundancy is not available in this
mode. Read and write performance is enhanced.
Select RAID 1 for mirroring disks This selection groups two disks together as one virtual disk with a capacity of one
single disk. The data is replicated on both disks. When a disk fails, the virtual disk continues to function. This feature
provides data redundancy and good read performance, but slightly slower write performance. The system must have at
least two physical disks to use RAID 1.
Select RAID 5 for striping with distributed parity This selection groups n disks together as one large virtual disk with
a total capacity of (n-1) disks. When a disk fails, the virtual disk continues to function. This feature provides better data
