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

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

To locate Recongure 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 Recongure from the Available Tasks drop-down box.
5. Click Execute.
Virtual Disk Task: Recongure (Step 2 of 3)
Does my controller support this feature? See Supported Features.
The virtual disk recongure Step 2 page enables you to select the RAID level and size for the recongured virtual disk.
If you selected Expand Capacity in Step 1, this page allows you to expand the capacity of the virtual disk. The Expand Capacity
option appears only for PERC H310, H330, H700, H710, H710P, PERC H800, H810, H730, H730P, H830, FD33xD/FD33xS controllers
with rmware version 7.1 or later.
To Recongure 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 aect 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.
